Short definition
A tool’s estimate of how hard it is to rank for a keyword.
Beginner In plain English
Keyword difficulty is a score (often 0–100) that guesses how much competition you will face. Higher means harder.
Professional How pros use it
Each tool calculates difficulty differently, usually from the backlink profiles of ranking pages, so scores are not comparable across tools. Validate by reviewing the actual results: page quality, intent match and site strength.
Examples
- A score of 12 for "bakery open sunday [city]".
- A score of 78 for "best running shoes".
More detail
A tool-specific estimate of how hard it would be to rank on the first page for a keyword.
In client work, you will often need to explain this term in plain language, so practice describing it in one sentence.
