SEMrush Rank is a custom ranking for domains. This is displaying how high of a presence a domain has on the Internet based on organic rankings and search traffic. In the example listed below, you can see that imdb.com had an SEMrush rank of 7 (September 2016 data). This means that at that time, IMDB was the 7th most present website on the Internet based on organic rankings and search traffic.
This number is calculated based on the visibility of the domain’s ranking for the keywords that are displayed through our database. The amount of information we show for this domain will be based on how we get our data.
