Moz.com released their latest survey results for search engine ranking factors. The 2015 edition is their largest ranking influence estimation project to date. There are two general data sets available. The Correlations data set shows the approximate influence of certain factors in a page’s ranking, as measured across 16,521 Adwords-suggested queries from early May 2015. The Survey Results data is a collection of the perceived influence and trajectory of certain ranking factors by 150 SEO professionals. Of particular note is the fact that mobile-friendliness of a website is the factor that more SEO pros think will increase in influence going forward.
