Keyword Difficulty
Keyword difficulty is a score that estimates how hard it is to rank on the first page for a keyword, based on the strength of the pages already ranking for it. A higher score means stronger competition and more effort to break in.
How keyword difficulty is estimated
Difficulty scores look at the pages already ranking for a term — their authority, backlinks and relevance — and summarise how tough that competition is, usually on a 0–100 scale. Different tools weight the signals differently, so treat it as a relative guide, not an absolute truth.
How to use it
Pair difficulty with search volume: the sweet spot is decent volume with manageable competition. New sites usually win faster on lower-difficulty long-tail keywords before chasing competitive head terms.
