Every hour spent on self-promotion is an hour not spent sharpening skills or helping clients.<\/p>\n<p><em>To stay ahead of the\u00a0masses, seek out and learn from SEOs who make their living doing, not teaching.<\/em><\/p>\n<h2>Can You Trust SEO Correlation Studies?<\/h2>\n<p>Much to the chagrin of <a href=\"https:\/\/artios.io\/making-google-seo-predictable-with-data-science\/\" target=\"_blank\" rel=\"noopener noreferrer\">people who understand statistics<\/a>, the SEO industry has popularized the idea that correlation with Google rankings can be used to measure the relative importance of different ranking factors.<\/p>\n<p>For example, a study may report that the <em>number of Linking C-Blocks to a domain<\/em> has a 0.26 correlation with Google rankings while <em>Exact Keyword Density<\/em> has a 0.14 correlation. Therefore, the authors claim, the number of Linking C-Blocks is a more significant ranking factor than Exact Keyword Density.<\/p>\n<p>Unfortunately, there are some flaws in this approach. Let\u2019s examine each in turn.<\/p>\n<h3>Even the Best SEO Correlations Are Not That Good<\/h3>\n<p>We often see SEO correlations presented on a graph that looks something like this one from the\u00a0<a href=\"https:\/\/moz.com\/search-ranking-factors\/correlations\">Moz study<\/a>.

Even the best SEO correlations are significantly weaker.<\/p>\n<p>This is partly due to the high degree of noise in web-scale data. Another factor is that all SEO studies use third-party data. Like <a href=\"https:\/\/en.wikipedia.org\/wiki\/Allegory_of_the_Cave\" target=\"_blank\" rel=\"noopener noreferrer\">Plato\u2019s famous allegory<\/a>, the data we look at is a mere shadow on the cave wall next to the real data locked away inside the walls of the Googleplex.<\/p>\n<p>With such messy data and weak correlations, there&#8217;s really only one responsible interpretation:\u00a0<span style=\"font-style: italic;\">&#8220;Factor X and Factor Y are both poorly correlated with Google results, but Factor Y slightly less so.&#8221;<\/span><\/p>\n<p>In that context, you can see how crazy it would be to conclude <span style=\"font-style: italic;\">&#8220;so definitely make sure you focus on optimizing Factor Y!\u201d<\/span><\/p>\n<h2>Correlation Does Not Equal Causation<\/h2>\n<p>It may be the biggest cliche in statistics, but it\u2019s a lesson many\u00a0are quick to forget in pursuit of a hot story.<\/p>\n<p>No matter how seductive it may be, correlation does not equal causation. Here are a couple of examples to illustrate this.<\/p>\n<p>Sales of organic produce and\u00a0autism rates have a very strong\u00a0<strong>0.99<\/strong> correlation, suggesting that the former can be used to explain nearly all the variation in the latter. Yet few (hopefully nobody!)\u00a0would conclude that organic produce causes autism.<\/p>\n<p>How about this one?<\/p>\n<p>Lemons imported from Mexico to US vs. US Highway fatalities have an equally impressive correlation of <strong>0.97<\/strong>. Who would conclude that importing lemons from Mexico leads to traffic accidents?<\/p>\n<p>So there is good reason to be wary of SEO studies drawing similar conclusions based on much weaker correlations.<\/p>\n<p>Finally, know that if you look at enough metrics, <em>even if they&#8217;re all completely unrelated<\/em>, you will find ones with strong correlations.<\/p>\n<p>The most famous example of this phenomenon was illustrated by Caltech\u2019s <span style=\"text-decoration: underline;\"><a href=\"http:\/\/www.forbes.com\/sites\/davidleinweber\/2012\/07\/24\/stupid-data-miner-tricks-quants-fooling-themselves-the-economic-indicator-in-your-pants\/#4cd991406509\" target=\"_blank\" rel=\"noopener noreferrer\">David Leinweber<\/a><\/span>. Mining a database of agricultural statistics, he found that butter production in Bangladesh had a 75% correlation with the movements of the S&amp;P 500.

The keyword phrase \u201c<a href=\"https:\/\/www.canirank.com\/reports\/public\/t9CNK1m-NMor6MSA9G32sxdNmfCRl3jHIzG0-t0aoXU\">lambs for sale<\/a>\u201d has little competition compared to SEO industry terms.<\/p>\n<p><em><span style=\"font-weight: 400;\">Only the top ranking page is well-optimized <\/span><span style=\"font-weight: 400;\">for their target keyword searches.<\/span><\/em><\/p>\n<p>For this keyword, the #1 ranking result is probably weaker than the 586th highest ranked result for the keyword \u201cSEO.\u201d<\/p>\n<p>Bottom line, <strong>not all results are playing by the same rules<\/strong>.<\/p>\n<p>Measuring correlations over a population of result sets this diverse is tough. Theoretically, we can \u201csmooth over\u201d these differences with sheer volume of data collected. But these are not small bumps you can simply iron out. These are Everest-sized mountains \u2014\u00a0fundamental differences you can&#8217;t smooth over even with a massive data set.<\/p>\n<p>There&#8217;s a reason search result sets tend to look so different. It&#8217;s inherent in\u00a0the nature of search engine algorithms, so\u00a0we&#8217;ll explore that next.<\/p>\n<h3>Algorithms for Search Ranking Factors Are Nonlinear<\/h3>\n<p>SEOs tend to oversimplify search engine algorithms. Search engines aren\u2019t a simple linear point-based system like you might use to rank football teams. It\u2019s not like you have 10 of those, 6 of these, and 4\u00a0of that, and therefore will outrank\u00a0another site that only has 9 of those, 5 of these, and 3\u00a0of that.<\/p>\n<p>In modern search engines, it&#8217;s more accurate to envision\u00a0many interconnected algorithms at work. Some of these algorithms may be rule or point-based, while others act\u00a0more like classifiers.<\/p>\n<p>For example, a classification algorithm may be used to determine whether a certain page is a &#8220;store&#8221; or a &#8220;review blog&#8221;. For a given product search, Google rankings factors may decide to return a 80% commercial stores\u00a0where the user can buy that product\u00a0and 20% informational reviews of that product.<\/p>\n<p>If your page\u00a0looks like a store, you&#8217;re competing against Amazon, Walmart, Ebay, and other massive etailers. But if you look like a review, your competition is limited to a\u00a0handful of other review bloggers \u2014 and sometimes no one at all. (We explain this strategy in more detail in our post on <a href=\"http:\/\/www.canirank.com\/blog\/outrank-amazon-5-expert-seo-secrets\/\">how to outrank Amazon<\/a>.)<\/p>\n<p>Weaker can outrank stronger. Sometimes it&#8217;s not\u00a0\u201c<em>Do you have more links than the other guy?<\/em>\u201d but rather &#8220;W<em>hat kind of site do you look like?<\/em>&#8221;<\/p>\n<p>At other times, scoring too high in one metric (such as exact match anchor text) can get you labeled a spammer. Too low and you&#8217;re irrelevant.\u00a0The best score is actually one somewhere in the middle, and that sweet spot may vary by keyword.<\/p>\n<p>Correlations\u00a0aren&#8217;t able to reflect that kind of non-linearity.<\/p>\n<p>It&#8217;s rare that\u00a0you can make a determination based on just one factor in isolation. To be prescriptive in figuring out how to improve a\u00a0site based on data you need to understand:<\/p>\n<ol>\n<li>What kind of sites Google favors for that keyword<\/li>\n<li>Why the current top-ranking sites rank where they do<\/li>\n<li>Given the characteristics of your site, what might be your best opportunity for breaking into the top ranks<\/li>\n<\/ol>\n<p>Search ranking algorithms are more layered and complex than many SEOs imagine. Simplistic correlation studies reinforce this misperception by implying that more is always better.<\/p>\n<h3>A More Nuanced Way to Look at SEO Data<\/h3>\n<p>While other people look at correlations, we try to understand <em>why<\/em> sites rank. Correlations and other descriptive statistics are merely a symptom of some\u00a0underlying mechanism. If you understand the mechanism at work, you can turn correlations and other data into actionable insights.<\/p>\n<p>CanIRank aggregates\u00a0over 200 individual SEO metrics into\u00a0six major Ranking Factor areas to make it easier for humans to understand and visualize\u00a0the interactions at work. This helps smooth over some of the noise of the messy underlying data, and see what factors the algorithm emphasizes for any keyword.<\/p>\n<p><a href=\"http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9.jpg\"><img decoding=\"async\" class=\"aligncenter wp-image-2329 size-large\" src=\"http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-1024x703.jpg\" alt=\"SEO median google search ranking factors scores by rank\" width=\"1024\" height=\"703\" srcset=\"http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-200x137.jpg 200w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-300x206.jpg 300w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-400x275.jpg 400w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-600x412.jpg 600w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-768x527.jpg 768w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-800x549.jpg 800w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-1024x703.jpg 1024w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/slide9-1200x824.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/p>\n<h3>What are\u00a0correlation studies really showing us?<\/h3>\n<p>What happens when you take the average of a diverse population? Characteristics of the largest sub-group within that population will dominate the averages. You&#8217;ll end up with a messy, watered-down description of that dominant sub-group, rather than a description of the population overall.<\/p>\n<p>In the case of SEO\u00a0correlation studies, that dominant sub-population is Big Brand websites.<\/p>\n<p>If you do the kind of naive analysis that most studies perform, you end up concluding that top-ranking pages:<\/p>\n<ul>\n<li>have more links<\/li>\n<li>use https<\/li>\n<li>have shorter domain names<\/li>\n<li>are older<\/li>\n<li>have lots of pages, etc.<\/li>\n<\/ul>\n<p>That more or less describes the characteristics\u00a0of a Big Brand site.<\/p>\n<p>But these posts go on to conclude that &#8220;therefore you should use https, use shorter URLs, get more links, etc&#8230;&#8221;<\/p>\n<p>But being\u00a0a Big Brand isn&#8217;t the only path to top rankings,\u00a0and it&#8217;s much more actionable for us to know how <em>sites like ours<\/em> manage to rank well. We&#8217;re interested in the exceptions, not the rule.<\/p>\n<p>Understanding the characteristics of small and medium-sized sites who make it on to page 1 is often much more actionable than taking an average across\u00a0all top-ranking sites.<\/p>\n<h2>How Robust Are SEO Studies?<\/h2>\n<p>Not all data is created equally. Analyzing\u00a0sample size, error rate,\u00a0distribution, and other characteristics allow\u00a0us to determine whether or not we can rely upon the conclusions of a given study.<\/p>\n<p>Unfortunately, SEO studies rarely\u00a0include that level of detail.<\/p>\n<p>If people are betting their livelihood on the conclusions presented in a study, it seems reasonable to\u00a0have some indication whether the data is reliable.<\/p>\n<p>One possible solution would be to introduce a standard indicating the robustness of any conclusion presented. Conclusions could be graded on a scale from \u201cUnclear conjecture\u201d to \u201cExtremely reliable\u201d. Below is a simple\u00a0Data Robustness scale I included in my presentations at this year&#8217;s <a href=\"http:\/\/www.ungagged.com\/speaker\/matt-bentley\/\">Ungagged Conference<\/a>.<\/p>\n<p>Without having to get into any statistical nitty gritty, attendees could distinguish between conclusions that were strongly supported by clear data\u00a0and those that were more speculative.<\/p>\n<p><a href=\"http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1.jpg\"><img decoding=\"async\" class=\"aligncenter wp-image-2331 size-large\" src=\"http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-1024x599.jpg\" alt=\"SEO data robustness on search ranking factors\" width=\"1024\" height=\"599\" srcset=\"http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-200x117.jpg 200w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-300x176.jpg 300w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-400x234.jpg 400w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-600x351.jpg 600w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-768x449.jpg 768w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-800x468.jpg 800w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-1024x599.jpg 1024w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1-1200x702.jpg 1200w, http:\/\/blog.canirank.com\/wp-content\/uploads\/2016\/12\/Copy-of-Data-Driven-SEO-1.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/p>\n<p>A robust conclusion means a large sample size, clear patterns relative to the noise or variance, and metrics not prone to error.
