SEO glossary

What is keyword difficulty?

Keyword difficulty (KD) is a score, usually from 0 to 100, that estimates how hard it would be to rank in Google’s top 10 for a keyword. Higher means harder. SEO tools calculate it from the pages that currently rank, most often from how many and how strong their backlinks are. It is a third-party estimate, not a Google metric.

Keyword difficulty, explained

Keyword difficulty checker FAQ

How is keyword difficulty calculated?

From the backlink profiles of the pages ranking in Google’s top 10 for the keyword: the stronger their links, the higher the score. It estimates how hard the keyword is to rank for, from 0 (easy) to 100 (hard).

Why do some keywords have no score?

Keywords with too few searches have no difficulty data. They are usually long-tail terms that are easy to rank for.

Do I need a project?

No. The SEO tools work on their own, in any market you pick. Keywords you find can be saved to a project in one click when you want to track them.

Can I share a result?

Yes. The search, the market and the open tab are all in the page address, so a link or a bookmark opens the same view. Anyone opening it runs the search with their own key; a repeat of something already looked up is served from the cache for free.
