Keyword Difficulty Checker

Ahrefs KD, SEMrush KD, and Moz Keyword Difficulty all look at one variable: how many backlinks the top 10 results have. They miss four things that actually determine whether you can rank:

• SERP feature saturation. If Google shows a Featured Snippet, PAA, Knowledge Panel, and local pack for your keyword, the organic blue links start at position 5 at best. KD 20 with four SERP features is harder than KD 60 with none.
• Content depth of top 10. Ten 3,000-word guides with original research are harder to outrank than ten 500-word thin pages, even at equal backlink counts.
• Brand concentration. If the top 10 are all Wikipedia, Forbes, Wirecutter, and Reddit, you are competing against domain authority a new site cannot match. Same KD against 10 smaller domains is winnable.
• Commercial intent mismatch. A commercial query where 6 of the top 10 are informational shows Google is not serving the transactional buyer. Winnable if you provide the commercial answer.

Our checker combines all four into a single score from 1-100. It is the KD we use internally before taking on a new engagement, because it predicts real ranking outcomes rather than just backlink counts.
