Free keyword tools cover 35% of the database paid ones see
We ran the same 50 seeds through three free tools and one paid suite, counting unique keyword suggestions.
— Paid suite: ▇▇▇▇▇▇▇▇▇▇ 100% baseline (12,400 terms)
— Best free tool (autocomplete scraper): ▇▇▇▇ 38% coverage, weakest on volume accuracy
— GKP free tier: ▇▇▇ 31%, banded volume only
— Answer/question tools: ▇▇ 19%, but best for question-intent long-tail
So what: free tools are fine for ideation and question mining. The gap shows up in coverage of mid-tail commercial terms and any reliable volume figure for prioritization.
Benchmark of the week: autocomplete-based free tools surface ~80% of question keywords a paid tool finds, but only ~25% of buyer-intent modifiers.
