Over the years, Google spokespeople have repeatedly denied that user clicks factor into ranking websites, for example — but the leaked documents make note of several types of clicks users make and indicate they feed into ranking pages in search.
Another major point highlighted by Fishkin and King relates to how Google may use Chrome data in its search rankings. Google Search representatives have said that they don’t use anything from Chrome for ranking, but the leaked documents suggest that may not be true. One section, for example, lists “chrome_trans_clicks” as informing which links from a domain appear below the main webpage in search results. Fishkin interprets it as meaning Google “uses the number of clicks on pages in Chrome browsers and uses that to determine the most popular/important URLs on a site, which go into the calculation of which to include in the sitelinks feature.”
