Who ranks for these keywords
The websites that rank most for a list of keywords.
Your agent sends up to 200 keywords and gets the websites that rank for them on Google, strongest first. For each site it sees how many of the keywords it ranks for and its average position. This shows who your competitors for a topic are.
