What is the Keyword Difficulty Score (KD)?
Keyword Difficulty (KD) is a predictive score from 0 to 100 reflecting how difficult it would be to rank for the keyword vs. competitors.
How is Keyword Difficulty calculated?
Our KD score takes into consideration the authority of the top organic pages for a keyword as weighted competition factors, plus search volume data, and runs a proprietary algorithm to normalize the predicted score on a scale of 0 to 100.
