Keyword Difficulty

What Is Keyword Difficulty?

Keyword difficulty is a score, usually on a 0-100 scale, that estimates how hard it would be to rank on the first page of search results for a given keyword, based primarily on the strength of the sites currently ranking.

How It’s Calculated

Most tools calculate difficulty by analyzing the backlink profiles of pages currently ranking on page one — more referring domains pointing to the top results generally means a higher difficulty score, on the logic that you’d need comparable link authority to compete. Different tools weigh this differently, which is why the same keyword can show noticeably different difficulty scores across platforms.

How to Use It in Strategy

Keyword difficulty is most useful alongside your own site’s current authority and search volume — a lower-difficulty, lower-volume keyword that’s genuinely winnable often delivers more real traffic than repeatedly chasing high-difficulty terms your site isn’t yet positioned to compete for. It’s a planning tool, not a guarantee, since difficulty scores don’t account for content quality or how well a page matches actual search intent.
