Topic Modeling for Marketers: The Future
In this series, we’ve explored what a topic model is, why topic models are important, how to build one, and how to choose when topic modeling is the appropriate methodology.

As with all forms of machine learning and software, topic modeling software continues to evolve and improve. What was possible a few months ago is substantially better today. What was impossible or very impractical previously is now within our reach.

With that, let’s turn our eyes forward.

The Future of Topic Modeling

Today, topic modeling is still largely based on two algorithms, LSA and LDA. These models are mathematically sound and very efficient for topic modeling purposes. However, they have one glaring flaw: they are context-free. The frequencies of words and phrases distributed throughout a corpus is how these algorithms work, but frequencies do not impart meaning.

For example, because topic modeling is categorical unsupervised learning, we cannot infer sentiment from a topic model. We would need to run that analysis separately, using categorical supervised learning methods. Today, this level of analysis is technically possible but out of reach for the average business user; only purchasers and users of high-end language modeling software have access to it.

Topic modeling will evolve in the coming months and years as deep learning technologies continue to be more broadly available and accessible. How will this impact topic modeling? In the example above, we would need to process sentiment as a separate, discrete process from the topic model itself. This is inefficient and scales poorly. Deep learning ties together different kinds of machine learning so that the output from one technique is the input to another technique, like assembling children’s building blocks.

Topic modeling will evolve to a deep learning model that recognizes patterns of context and sentiment, as well as incorporating the current mathematical techniques. It may, depending on the evolution of deep learning technologies, even incorporate computer vision, to recognize the spatial nature of text and its role in sentiment and tone.

In time, topic modeling will be a part of artificial intelligence’s understanding of human language – a powerful tool that will only improve our ability to understand our audiences at massive scale.

These are exciting times for marketers. We are on the cusp of truly understanding our audiences at every level, in every way, as our artificial intelligence capabilities grow. If you haven’t already begun experimenting with AI and machine learning in your marketing practice, topic modeling is a great place to start.

Topic Modeling for Marketers: Choosing
Topic modeling is one antidote to the overwhelming volume of content created every day that marketers must understand. In this series, we’ll explore what topic modeling is, why it’s important, how it works, and some practical applications for marketing.

Part 4: When To Choose Topic Modeling

Now that we’ve built a topic model and learned how to interpret it, we should spend some time understanding when topic modeling is and is not appropriate.

Topic modeling is a part of machine learning; machine learning is broadly divided into two categories and two kinds of data.

First, our two kinds of data are continuous and categorical. Continuous data is typically numerical data; in marketing analytics, we call these metrics. A general rule of thumb is that if we can perform mathematical operations on data, it’s continuous/a metric.

Categorical data is typically descriptive data; in marketing analytics, we call these dimensions. These are typically non-numerical things we have to count; for example, someone’s allergies would be wheat gluten or shellfish. In a database, these would be listed as words; to make use of them, we have to count them up first and then perform math on the counting, but never on the actual data itself.

The categories of machine learning are supervised and unsupervised; in supervised learning, we are analyzing data to understand a known outcome. For example, if we want to know what influences purchasing decisions, we would use a technique like a random forest to process our numerical data and tell us what makes up a purchasing decision.

In unsupervised learning, we don’t know what the outcome is. We use machine learning to help us understand the data by classifying it, simplifying it, and bringing order to it.

Here’s a chart that helps simplify the above:

What kinds of questions might each category answer?
- Supervised learning of continuous data: What drives X/causes X?
- Supervised learning of categorical data: How many of X occurred?
- Unsupervised learning of continuous data: What relationships are in our metrics that we can’t see?
- Unsupervised learning of categorical data: What’s in the box?
Let’s look at four brief examples:
- Supervised learning of continuous data: predict when search interest in our top SEO keyword will be highest
- Supervised learning of categorical data: classify which pictures we post most on social media
- Unsupervised learning of continuous data: how do we understand the relationship between page traffic and social sharing metrics?
- Unsupervised learning of categorical data: what words, phrases, and topics do our favorite influencers use in our field?
Why does this all matter? Topic modeling fits squarely in the unsupervised learning of categorical data. We have a collection of something unknown – a large body of text – and we want to understand it. To do so, we have to associate and reduce the complexity – all the words – to something manageable and understandable by the human mind.

When Not To Choose Topic Modeling

Based on the above, we should choose topic modeling as a method any time we need to understand what’s in the box, what’s in a large bag of words.

When is topic modeling the wrong choice? When we have a problem that is:
- Mathematical in nature (continuous data)
- Categorizational in nature (supervised learning)
For example, if we wanted to know which social media updates were the most popular, that’s not a question topic modeling will answer. That’s just straight statistics.

If we wanted to know which word or phrase was the most frequently used in our social media updates, that’s not a question topic modeling will answer, either. That’s a form of text mining called term frequency analysis – and it presumes we know what words to count.

Only when we have a large body of text that we need to reduce to human scale is topic modeling the best choice.

Next: Wrapping Up

We’ll look back over the series in the next post and give some tips as to where to go next in our machine learning journey. Stay tuned!

Topic Modeling for Marketers: Understanding
Topic modeling is one antidote to the overwhelming volume of content created every day that marketers must understand. In this series, we’ll explore what topic modeling is, why it’s important, how it works, and some practical applications for marketing.

Part 3: How to Interpret Topic Models

One of the key flaws of topic models and their visualizations is that, to the uninitiated, they are difficult to glean insight from. Their raw outputs are complex, and the accompanying visualizations often confuse more than explain. Today, we’ll examine ways to interpret and understand topic model outputs, to better glean insights from them.

Let’s begin by examining some of the most common topic model outputs.

Topic Model Top 10 Chart

One of the most common visualizations of a topic model is a simple bar graph chart of the different topics and the associated strengths of keywords within each topic:

This graph visualizes our topics – usually an arbitrary number such as 10, 20, or 25 – and the importance of words within each topic. It lacks, however, a sense of relevance of the topic overall to the entirety of the text we’re measuring, but it’s not a bad start.

Here’s another basic visualization of topics and the relevance of each topic to the overall corpus:

This graph has the opposite problem; we have no way of understanding the weight of individual words, but we understand the relevance of each topic to the corpus overall.

Topic Models Require Domain Knowledge

Recall that topic models are nothing more than statistical analyses of large bodies of text. They are mathematical summaries of the most prominent words. Thus, interpreting topic models means we need to have domain knowledge of the overall topic.

For example, in the above topic model of tweets about me, I understand each topic well because I am a domain expert on me, as anyone would be about themselves. I’m able to understand the relevance of each topic without needing the language context itself. I can tell you which topics are from which conferences and events, or what themes people associate with me most.

If this were, say, an analysis of the tweets of someone expert in financial engineering, I would have little to offer in the way of understanding. I wouldn’t know the person, and I don’t have domain expertise in financial engineering.

Thus, developing at least cursory domain knowledge of what we’re modeling is a pre-requisite to extracting the most value out of topic models. Alternately, if we have access to a domain expert, we will be able to create value.

Three Ways to Read Topic Models

Once we’ve established that we’re able to read and provide our own context to a topic model output, we begin divining meaning and insight from it. To make the most use of topic models, we should ask ourselves three key questions when looking at a model.

What’s Expected?

In examining a topic model, or several side-by-side, we ask what’s expected? What should be there? What’s the common ground?

This is especially important if we are using topic modeling to provide competitive marketing insights. What are the common ground topics among two different companies? Understanding common ground helps us to understand what won’t be a competitive advantage.

Likewise, if we were performing topic modeling to understand influencers, what topics do they share? If we’re not also sharing those topics, we might be missing a key part of the conversation.

What’s Anomalous?

When we look at topic models, we look for anomalies, for unexpected things, for topics and words that don’t make sense.

For example, if I was analyzing tweets about me and saw a prominent topic or keyword that had nothing to do with me, that would be a great starting point for more investigation. Do I have a data problem? Or is there a topic that others think I’m knowledgeable about that I’m not – but represents an opportunity?

When we use topic modeling to understand conversations in our market, anomalies represent opportunities. Is there a new angle we’re not participating in? Is there a new competitor we were unaware of?

What’s Missing?

The third and most difficult analysis in topic modeling is what’s missing. What’s not there that should be there? Understanding what’s missing requires deep domain knowledge, to know what else exists in the domain.

Business folks love to call this the green field, the white space, the blue ocean, and these empty spaces are valuable for their lack of competitive pressure. However, in topic modeling, we must be equally careful that we didn’t inadvertently exclude data, creating an artificial space that doesn’t really exist.

Once we do find something missing, we have a great starting point for building marketing campaigns and content to fill that space.

For example, I was recently looking at conversation at a conference, and the Internet of Things (IoT) was a prominent topic. However, completely absent from that conference’s conversations were security of IoT and machine learning of IoT data. These two secondary topics should have been there, and so that audience, that conference had a glaring omission. A savvy marketer would then approach that conference and its attendees with IoT security and data analysis offerings to fill that awareness gap.

What’s Next?

In the next post in this series, we’ll examine when to use and not use topic models. As useful as they are, when are they most applicable? When should we choose a different tool? For the answers, stay tuned!

Topic Modeling for Marketers: Building
Topic modeling is one antidote to the overwhelming volume of content created every day that marketers must understand. In this series, we’ll explore what topic modeling is, why it’s important, how it works, and some practical applications for marketing.

Part 3: The Topic Modeling Process

Now that we have a base understanding of what a topic model is, let’s look at the process of building one. Building a topic model resembles many other statistical and data engineering processes, with four discrete stages:
- Extract
- Transform
- Load
- Process
Let’s dig into each stage.

Extract

As with any form of data analysis, we need to first extract our data. Data for topic modeling comes from any body, any corpus of text. Topic models are limited only by our access to computational power; thus, we could conceivably build a model spanning the entirety of the written human language. However, for more practical purposes, chances are we’ll only be working with a maximum of a gigabyte of text or so.

How much text is a gigabyte? It’s about a million social media posts, about a half million news articles, or about ten thousand books.

Topic modeling also requires text at volume. A handful of social media posts will generate a poor quality model. My general rule of thumb is that if it takes you less than an hour to read the entirety of what you’re trying to analyze, it’s not worth building a topic model. For example, fifty tweets isn’t worth building a model. Five articles aren’t worth building a model.

When extracting text, we need to store it in a machine-friendly format. For the English language, ASCII text is the preferred format. For non-English languages, UTF-8 is the preferred format.

Once extracted, text data is stored typically either in a flat file or in a text-friendly database.

As an example file, let’s use a corpus of tweets mentioning me.

Transform

The transformation of text is one of the most important parts of topic modeling. Text must be well-formed, free of junk that will cause software to reject it. If our text didn’t come out clean in extraction, we must force it to either ASCII or UTF-8 formats. Popular text editors such as BBEdit for the Mac, UltraEdit for Windows, or Atom for cross-platform use, help to reformat text correctly.

One type of text that’s prevalent in digital works is HTML-encoded entities. These are special codes used in HTML – web pages – that will show up in topic models with weird looking phrases like emsp and nbsp. I maintain a running list of these entities and use find/replace scripts to clean them up.

In our example dataset, here’s what it looks like once I clean up a lot of the obvious junk:

Once our corpus is clean of the most obvious garbage, we must undertake the next stage of transformation using our software.

A Word on Topic Modeling Software

For topic modeling, we have a number of software choices. Some software, such as IBM Watson Natural Language Understanding or Google Cloud NL, does much of the transformation, loading, and processing automatically, in exchange for a per-use fee. For beginners dealing with relatively small quantities of text, I recommend starting here.

For more technical users who have large quantities of text that would either be cost-prohibitive or technically challenging for on-demand services, the software of choice are libraries for topic modeling in R or Python. I’m fond of packages such as topicmodels and quanteda in R.

For users with very high volume or specialized customization, dedicated academic software packages such as MALLET from the University of Massachusetts are the way to go.

For the remainder of this post, we’ll look at a topic model built using R.

Transforming Text

After we’ve obtained a clean corpus, we need to load it for further processing. Our software conducts a process known as tokenization, where we break up our text into individual words and assign the numerical values as we explored in the previous post.

Once our document has been digested into tokens, we need to normalize the words using a process called stemming. Stemming reduces words down to their root forms, for more straightforward understanding. For example, read the following paragraph:

The taste of a red wine shines best in tastings paired with aged hard cheeses. A Merlot’s tastiness comes across boldly in a pairing with a smoked gouda.

Stemming would reduce taste, tastings, and tastiness to the root word taste. Paired and pairing would be reduced to pair. By reducing these words to their root forms, we obtain a more clear understanding of the paragraph at a summary level and elevate the prominence of these key words.

When we do tokenization and stemming, we visualize our corpus of tokens using simple tools like word clouds, just to quality check:

Above, this is what the word cloud of tweets about me looks like.

Loading and Processing Text

Once we’ve completed tokenization and stemming, we’re ready to generate the actual model. The gold standard algorithm used in topic modeling today is called Latent Dirichlet Allocation, or LDA. Virtually every major topic modeling software package uses LDA to build its models.

LDA looks at the mathematical relationships described in the previous post – what words are near other words frequently, how words interact, etc. to build our actual topic models.

The output of LDA processing varies based on what we ask of our software. Sometimes we’ll want a visualization of the different topics, such as this chart of graphs:

Other times, we’ll want a straight-up spreadsheet:

Still other times, we might rely on advanced visualizations or interactive displays.

The important takeaway is that we must be able to interpret and glean insight from our LDA outputs. Does looking at the above outputs confuse, rather than clarify? It should – for now. In the next post in this series, we’ll explore how to interpret topic models and transform these raw outputs into important insights we can act on. Stay tuned!

Topic Modeling for Marketers: Definition
Topic modeling is one antidote to the overwhelming volume of content created every day that marketers must understand. In this series, we’ll explore what topic modeling is, why it’s important, how it works, and some practical applications for marketing.

Part 2: What Is Topic Modeling

Let’s begin by answering the question: what is topic modeling?

Here’s a great definition from KDNuggets:

Topic modeling can be described as a method for finding a group of words (i.e topic) from a collection of documents that best represents the information in the collection. It can also be thought of as a form of text mining – a way to obtain recurring patterns of words in textual material.

The easiest way to think of a topic model is a word-based summary of a body of text. Think of how a table of contents outlines a book, or how a menu outlines the food at a restaurant. That’s what a topic model essentially does.

Topic models first came into use in the late 1990s, with Thomas Hoffman’s probabilistic latent semantic analysis. They’ve become more popular over the years as computing power has increased.

How Do Topic Models Work?

Topic models are a product of mathematical and statistical analysis. In essence, they assign numerical values to words, then look at the mathematical probabilities of those numerical values.

For example, consider this sentence:

I ate breakfast.

We could assign arbitrary numerical values to this sentence, such as I = 1, ate = 2, and breakfast = 3.

Now, consider this sentence:

I ate eggs for breakfast.

We would have a sequence like 1, 2, 4, 5, 3 using the previous numbers.

Next, consider this sentence:

Mary ate breakfast with me.

This would have a sequence like 6, 2, 3, 7, 8.

Put these sequences together:

1, 2, 3

1, 2, 4, 5, 3

6, 2, 3, 7, 8

We begin to see increased frequencies in this table. The number 2 appears 3 times. The number 3 appears 3 times. The number 1 appears twice, and always next to the number 2. The number 3 moves around a bit.

This mathematical understanding of our text is how topic models work; statistical software predicts features such as:
- How often does a number (word) appear?
- How often does a number (word) appear only within one document, but not in others?
- How often do certain numbers (words) appear next to each other?
While this seems like a lot of work to analyze three sentences, the value of topic modeling is performing this kind of analysis on thousands or millions of sentences – especially when time is important.

For example, suppose we’re attending a major conference like Dreamforce or CES. If we want to participate in relevant conversations, we should know what the most important topics are on the minds of attendees. However, mega-events often generate hundreds or thousands of social media posts per hour. No human or even group of humans could reasonably keep up with the raw feed from such an event. A machine will.

Walking Through a Topic Model

In the next post in this series, we’ll explore the process of creating a topic model. Stay tuned!

Topic Modeling for Marketers: Introduction
Human marketers fall farther behind every day.

In 2017, marketing analytics firm Domo released its fifth edition of Data Never Sleeps: The Internet Minute.

In Data Never Sleeps 5.0, they revealed the following statistics which occur every 60 seconds on the Internet:
- Twitter users send 456,000 tweets
- Instagram users post 46,740 photos
- Google users conduct 3,607,080 searches
- SMS users send 15,220,700 texts
Consider these statistics for a moment. This is what Mark W. Schaefer called Content Shock in 2014: massively overwhelming amounts of data. In my own analysis of just the news, nearly 200,000 news stories are published per day (according to the Google News database).

How long would it take to read 200,000 news stories? If every story were a mere 300 words, and every reader read at 150 words per minute, it would take 400,000 minutes to read a day’s worth of news.

Recall that there are only 525,600 minutes in a year. It would take nearly a year to read a day’s worth of news.

How long would it take to read 456,000 tweets? Assuming it takes us 5 seconds to read all 280 characters, it would take us 633 hours to read just 60 seconds’ worth of the world’s tweets.

We marketers are faced with overwhelming amounts of data and no practical way to read through it all, or even a significant fraction of it.

The Consequences of Content Shock

What happens when we simply can’t read it all?

For those of us analytically-minded marketers, missing content means missing data. We miss mentions of our brands, our companies, ourselves. Our analysis of what people are saying is incomplete; our insights are based on partial, potentially flawed data.

For those of us charged with creating content, we try to raise our voices. We make more content without necessarily making better content. Without complete or representative insights, we make content that’s tone-deaf or irrelevant to what our audiences want to hear about.

In both cases, we are positioned for failure. We will make irrelevant content and fail to understand what our audiences care about, what our customers want to buy, what our employees need.

Avoiding Failure

How do we avoid these twin failures of broken insights and broken outputs? The solution is straightforward: learn how to read all the relevant news. Learn how to digest all the relevant data, sort through it, and build our insights.

The reality is that we mere humans will never accomplish this unassisted. With the avalanche of data, we have no way to humanly read that much information unless we hired everyone creating content – all 3 billion of us.

Fortunately, we no longer must rely on ourselves. We now have extremely powerful tools at our disposal to read for us, digest, and build models of understanding with machine learning technology. This technology is known as topic modeling, and in this series, we’ll explore what topic modeling is, how it solves our content shock problem, and practical ways to apply it to our marketing.

Stay tuned!

AI Promises Automatic Minimum Competence
One of the promises of artificial intelligence is taking tasks that humans do and scaling them massively, while adhering to defined best practices. This promise will help companies and brands achieve automatic minimum competence, with gigantic implications. Let’s dig into what these are.

The Human Experience

Consider the average human experience – that is, the experience an average human creates for a customer in a business setting. An average human begins a new job or a new task with near-complete incompetence. Whether it’s cooking a souffle or programming a machine, the average human tends to do exceptionally poorly the first time they perform a task.

Over time, what happens? The human achieves mediocrity, then competence, and finally – after thousands of hours – excellence. Thousands of hours translates into years, if not decades, of work in order to reach excellence.

For the majority of human workers, their tenancy in any given job is fewer than 5 years. Thus, their level of excellence at a job-specific task is likely to never exceed competence; only a select few workers will dwell long enough in a job to achieve excellence and mastery.

Thus, the average human experience delivered to customers is likely to be mediocre at best, incompetent at worst, and only rarely excellent. Let’s compare artificial intelligence.

AI Skips The Wait Time

The time to competency for an artificial intelligence system, a machine learning system, is significantly shorter than for humans. This time to competency is shorter for three reasons.

First, AI systems typically will begin with a set of rules that humans must necessarily understand and adhere to. Just learning the rules can take 4-8 weeks on the job for humans, much less excelling under those rules. Machines will start with rules as boundaries at the outset.

Second, AI systems begin with a training data set of competence-based outcomes. No one would dare train a commercial production chatbot with the most surly interactions from the least-engaged employees. Instead, they’d train the chatbot only on interactions with customers which resulted in high customer satisfaction scores. Likewise, no one would build a machine learning system designed to forecast unsuccessful business outcomes as a desired goal; we would train the system to forecast using successful business outcomes.

Third, AI systems learn in a networked way. When a single human employee learns a new task, that knowledge tends to remain confined within that human mind. When an AI system learns a new task, or learns from an error, the entire system learns. Every instance of that AI system learns from the past and all systems immediately upgrade to the latest knowledge.

As a result, instead of beginning at zero and taking years to learn, make mistakes, and eventually adjust, our AI systems will begin at minimum levels of competence. Just as fast food chains and industrial food production systems ensure uniform, acceptable food outcomes like hamburgers and french fries, so too will our AI systems transform our information and knowledge-based outputs into uniform, acceptable business outcomes.

Automatic Minimum Competence Consequences

We will see two consequences from automatic minimum competence. First, overall customer satisfaction (and thus repeat business/referrals) will increase. Customers will have more satisfying interactions with AI than with humans on average. Companies, as a result, will see higher purchases, more repeat business, and greater satisfaction scores.

Second, new entrants to the workforce or those changing jobs will face a much higher barrier to entry. Only those career positions which require the unique skills of humans will be open to the entry-level workforce, because no rational business will choose an incompetent human over an automatically-competent machine whenever the choice is possible.

Prepare yourself and your career by achieving excellence today in what you do; for those technically-inclined, developing new ways for machines to model competence and excellence will be highly-lucrative opportunities in the months and years to come.

The AI-Powered SEO Process: Conclusion
We’ve reached the end of our AI-powered SEO series. We’ve now explored the use of machine learning technologies to significantly improve our SEO efforts, understanding what content will work best and who to reach out to for link creation.

What’s next depends on who we are as marketers.

The Marketer With Some SEO Responsibilities

For the average marketer whose responsibilities include SEO, but SEO is not your primary job responsibility, the techniques in this series should serve you well. You’ll need to be the “glue” that joins each step to the next step, applying human judgement along the way.

By and large, most marketers will fall in this category, and that’s appropriate. You also have the freedom to pick and choose among the techniques we’ve reviewed. Not every technique is applicable to every business. For example, the influencer/key opinion leader mapping step applies to companies with a social graph. Some industries simply have little to no social media presence, and so we’d need to use either a different form of influence mapping or skip that step entirely.

That said, for the average marketer, using these AI-powered SEO techniques will give you a significant advantage over all but the most well-funded competitors, until SEO vendors catch up. Be an early adopter and start creating your SEO advantage today.

The Full-Time SEO Professional

For the marketer whose responsibilities are primarily SEO, we should consider another kind of AI-powered SEO: deep learning-powered SEO. Deep learning takes machine learning techniques and chains them together, each step using data from the previous step. Much of the data manipulation and feature engineering in each of the steps in our process is something that could be automated, given enough time and budget.

I would expect the leading SEO vendors, if they have any sense at all, to be applying deep learning to their existing SEO techniques and tools. A sufficiently skilled and motivated developer and data scientist could transform our entire AI-powered SEO process into a single massive piece of code, powered by deep learning. This software would execute the process in full, from beginning to end, ingesting data sources and propagating results forward and backwards along the chain.

Creating a system like this, with deep learning technologies, will be an expensive and intensive endeavor. However, the first companies which manage to do it well will create a nearly insurmountable first-mover advantage. Their ability to attract organic search traffic will leave rivals at a severe disadvantage, with shrinking traffic and lower growth.

The Future of SEO is AI

Whichever path we find ourselves on, the future of SEO is AI, because the present-day search engines are powered by AI. We are not smart enough as mere humans to outsmart the machines of massive companies like Microsoft and Google. Only by applying the same technologies and powers do we stand a chance of creating search advantage in our marketing.

Finally, don’t forget the most basic fundamental: search algorithms will continue to evolve to surface what consumers want. At the end of the day, there’s still a human on the other end of the search query, so if you have no capabilities in AI, all is not lost. You simply must create amazingly great content.

I wish you the best in your own AI-powered SEO endeavors!

The AI-Powered SEO Process: Distill and Reach Out
Search engine optimization, or SEO, has changed significantly in the past few years. Thanks to the power of machine learning and artificial intelligence, the only way to build a sustainable, long-term SEO strategy is to create content people want to share. To combat these new trends, we need to employ our own machine learning technology to find what works and perform modern SEO at scale.

In this post, we’ll examine steps 9 and 10 – distillation and outreach.

Distilling Influencer Shares

What influencers share is just as important as who the influencer is. If we know who’s relevant to an influencer, we better determine whether that influencer’s sharing will have an overall impact on our SEO.

Let’s take, for example, our attribution analysis example from the last post. Of the influencers we identified, what have they shared? Using straightforward URL extraction code found in any modern programming language like PHP, Python, Ruby, etc., we find the individual articles shared:

We also summarize by domain name:

What do we do with this information?

SEO Outreach To Shared Sources

As we determined previously, sharing and inbound links have a strong positive relationship. The most logical next step is to determine how causative content is to sharing. To do so, examine the lists of pages and domains above.

Again, using any modern SEO tool such as the Moz toolbar or API, determine the SEO value of the shared content. Which publications, blogs, and sites have the highest authority that, if linked to us, would confer significant search benefit?

Once we’ve identified which publications confer greatest potential benefit, then we pursue the very human-powered process of outreach and relationship building. This is the one part of the SEO process that machines cannot effectively automate currently; while plenty of marketing automation tools can programmatically mass mail people, results are typically very poor. Take the time instead to build relationships with the most valuable targets.

The goal of outreach is to secure links in upcoming or current content that links back to the contextually appropriate content we created in step 7 of the process, informed by the timing predicted in step 6.

Reach Back to Influencers

Once we’ve secured links in high-ranking sources, we further amplify the impact of those sources by ensuring our key opinion leaders have seen and potentially shared our high-value content, both from the linked sites and our original source content.

Next: Wrapping Up

In the final post in this series, we’ll wrap up and review.

The AI-Powered SEO Process: Associate
Search engine optimization, or SEO, has changed significantly in the past few years. Thanks to the power of machine learning and artificial intelligence, the only way to build a sustainable, long-term SEO strategy is to create content people want to share. To combat these new trends, we need to employ our own machine learning technology to find what works and perform modern SEO at scale.

In this post, we’ll look at step 8: associate.

Influencers and SEO

Before we delve into the how, let’s address influencers, social media, and SEO. First, I took a look at more than 150,000 URLs of every kind, from mass media to corporate pages to individual blog posts. What’s the relationship between social media sharing and equity-passing inbound links?

We see a strong correlation between total social shares on any social network and equity-passing inbound links. This passes the common-sense test as well – someone who finds a link that’s worth sharing will also probably find that link worthwhile to include in content they publish.

What the above doesn’t prove, however, is which comes first – causality. Does a link worth sharing find its way into a piece of content, or does a link in a piece of content find its way into social media?

While it’s something of a generalization, sharing a piece of content is significantly less work than embedding a link to content in media. A cat could accidentally tap the share button on a smartphone. Encoding a link into content requires a very lucky cat. Thus, it’s likely that if we generate mindshare among influential social media audiences, we’ll see links to our content also appear in other online content.

With this understanding, how do we determine who could share our content?

Enter Influencer Identification

Social media monitoring tools of all stripes are capable of identifying links to existing content. Logically, if we know who our audience is and the terms/phrases/topics they search for, we should be able to identify to shares and links to similar content.

Let’s say I want to dig into attribution analysis as a term to rank for, based on steps 1-7 of our process. Who talks about attribution analysis? Who shares content about it? What do they share? Using influencer identification tools such as network graphs and centrality indexing (previously written about here), we identify who these people are.

First, we extract our data from social media monitoring software. I’ve been testing out Brand24 and have found it capable. Other services like Sysomos or Zignal Labs are also quite good.

Next, we map who talks to whom. I wrote custom software to extract this sort of thing, but it’s quite straightforward – make a network graph of your social media mentions. For network graphing, I recommend Gephi as it’s both free and relatively easy to learn.

Finally, we validate that indeed, this is the right crowd by running a topic model on the content they share.

This looks good – it’s on target with what I’d expect people talking about attribution analysis to be talking about, and marketing (my specialty) is prominent across the topics. We’ve got the right crowd.

Next: Who Shares Ranking Stuff

Now that we know who’s got the juice, we need to know whether they share links that eventually benefit from high rank. In the next post, we’ll mine that data. Stay tuned!
