SEO Ranking Factors

You can find the most important factors in our overview of all rank correlation coefficients. These are all the factors we have analyzed and consider relevant. We have presented the relationship between Google search results and the various factors influencing it using the Spearman correlation - a high positive correlation coefficient occurs for a factor if higher ranking pages have that feature / or more of that feature, while lower ranking pages do not / or have less of that feature. In addition to providing an overview of the changes in correlation since last year, we have extended our analysis in 2013 to include many relevant new factors.
