When a paid tool is still worth it
We are not here to bash the big platforms — they are genuinely excellent. If you need a vast historical backlink index, daily automated rank tracking across hundreds of keywords, or white-label client reporting at agency scale, a subscription to Semrush, Ahrefs or SE Ranking will serve you well. KeywordNumbers is built for the far more common case: you want a quick, reliable answer for keyword research, an on-page check or a technical audit — without a monthly bill or a sign-up wall in the way.
Common questions
Is there a free alternative to Semrush and Ahrefs?
Yes — KeywordNumbers gives you 35+ free SEO tools covering keyword search volume, research, difficulty, technical checks and YouTube tools, with no sign-up, no card and no monthly fee. It handles many of the everyday jobs people open Semrush or Ahrefs for.
Do I need an account or card to use it?
No. Every tool works straight away in your browser — no login, no card, and no daily search limits.
What do the paid platforms do that you do not?
They hold enormous historical backlink indexes, daily rank-tracking dashboards and enterprise reporting that a free tool does not try to match. For everything else, KeywordNumbers is a fast, free option.
Is it really free forever?
Yes. There is no trial clock and no push to a paid tier — it is supported by light advertising and optional donations rather than subscriptions.
