What is the SERP similarity?

When you are working in SEO, you often come across the situation where you quickly want to know whether you can rank two similar keywords in a single page or need to create separate article. The way to answer this question is to manually check the SERPs (Search engine results pages) to see how many common URLs are ranking for each keyword.

If we see a large number of similar pages ranking for both keywords, we can assume that both keywords can be targeted on a single page and if we see a few common URLs, then we can assume these keywords need separate pages.

Our free SERP analysis tool removes the need for manually checking the search results; we'll look for you.
