For the SEO World Rankings study, Searchmetrics analyzed the search results data from ten national Google indexes: (Austria), (Brazil), (Germany) (France), (Italy), (Spain), (Switzerland), (Turkey), (United Kingdom) and (United States)

The measure of search visibility used in the analysis is Searchmetrics’ SEO Visibility score, an index score which quantifies how prominently a website appears in organic search results. It is based on the organic rankings of the millions of keywords that Searchmetrics tracks in each country every week. The calculation for the SEO Visibility score is based on:

  • The number of times a domain appears in the search engine results pages (SERPs) across the keyword set
  • Its prominence within those SERPs (a higher ranking equates to a higher visibility score)
  • The competitiveness of the keyword (higher search volumes equate to a higher visibility score)

To create the list of the top ten most visible websites in each country, Searchmetrics took an average of several data points taken throughout the year.

To work out the five ‘Global Champion’ sites that are most visible across national boundaries, Searchmetrics analyzed the number of countries where the domain ranks in the top ten in terms of SEO visibility, then sorted by no of 1st places, no of 2nd places, no of 3rd places etc.
