How this service works
Keyword difficulty score (0-100) for up to 100 keywords (DataForSEO Labs Bulk Keyword Difficulty).
Output
Returns a JSON array where each entry contains the original keyword and its difficulty score from 0 (very easy) to 100 (extremely hard to rank), along with any keywords that were not found, and the language and location codes used for the lookup.
Example use cases
Content gap prioritization for blog
“I have a list of 20 blog topic keywords — can you get the keyword difficulty scores for all of them in English for the US market so I can prioritize the ones under 40?”
German market SEO assessment
“Check the keyword difficulty for 'laufschuhe', 'sportschuhe kaufen', and 'joggingschuhe' in Germany (location code 2276) with language set to de — I need to know how competitive they are before building content.”
Low-competition keyword filtering
“Here are 50 keywords my team brainstormed for our SaaS product — get their difficulty scores in English for the US so I can filter out anything above 60 and focus on the easier wins.”
