Keyword Difficulty

Keyword difficulty (KD) is a metric that estimates how hard it is to rank in the top 10 organic results for a given keyword. Most tools express this as a score from 0 to 100, where higher means more competitive.

Difficulty scores are calculated from the link profiles of pages currently ranking. A keyword with all top-10 results having high Domain Rating (DR) scores and many referring domains is genuinely hard to displace.

KD is directional, not absolute. A page can rank for a high-KD keyword with exceptional content that exactly matches search intent — particularly if current results are thin or poorly aligned. Conversely, a low-KD keyword with strong incumbent pages may be harder in practice than the score suggests.
