When Moz undertook this year’s Ranking Correlation Study (Ranking Factors), there was a desire to include data points never before studied. Fortunately, SimilarWeb had exactly what was needed. For the first time, Moz was able to measure ranking correlations with both traffic and engagement metrics. Using Moz’s ranking data on over 200,000 domains, combined with multiple SimilarWeb data points—including traffic, page views, bounce rate, time on site, and rank—the Search Ranking Factors study was able to measure how these metrics corresponded to higher rankings. These metrics differ from the traditional SEO parameters Moz has measured in the past in that they are primarily user-based metrics. This means that they vary based on how users interact with the individual websites, as opposed to static features such as title tag length.
