rank.fast

Free keyword ideas tool

Real keyword research without the subscription gate: enter a seed keyword and get the questions, comparisons, and long-tail variations people actually type into Google, straight from Autocomplete. Free, no signup, 5 keywords a day. Pairs with our free index checker.

What you get, and what you don't

The tool expands your seed through Google Autocomplete in eight frames: the plain term, question forms (how, why, can), comparisons (vs), and qualifiers (for, without, best). Everything returned is a real phrasing Google has seen people type; that's the point. What you don't get is search volume numbers: those come from paid data resellers, and every "free" tool showing volumes is either estimating or upselling. Real phrasings without volumes beat guessed volumes for deciding what to write, because a page targets a phrasing, not a number.

How to use the output

Why free

Autocomplete data costs us fractions of a cent to fetch, and keyword ideas are the start of the loop our paid products serve: you write the page, you check it's indexed, and if it isn't, indexing is what our service fixes. Need more than 5 a day? A free rank.fast account raises the limit to 25, and the same tool is available inside Claude via our connector (https://app.rank.fast/api/mcp).
