Content and on-page SEO
Keyword difficulty
Also called KD
Keyword difficulty is an estimate of how hard it would be to rank on the first page for a keyword, usually based on the authority of the pages already ranking.
How to use it
Each SEO tool calculates difficulty its own way, so treat it as a rough guide rather than a fact. New sites should start with lower-difficulty, high-intent keywords and build authority before targeting the hardest terms.
Look beyond the score
- Open the results: are the ranking pages actually good answers?
- Check whether smaller sites rank, which suggests a gap.
- Weigh business value: a hard keyword with buyer intent may be worth the effort.
