Free Semrush Alternative: 21 SEO Tools, No Sign-Up
Is there a free alternative to Semrush? Yes. InRankSEO covers the parts of Semrush that matter for organic SEO: on-page audits, keyword research, content planning, schema and Core Web Vitals. All 21 tools are free to run with no sign-up and no credit card. You lose the paid PPC, backlink index and market intelligence layers, but for organic work you keep the essentials.
THE SHORT ANSWER
Is there a free alternative to Semrush?
For organic SEO, yes. If your work is auditing pages, finding keywords, planning content and checking technical health, the free InRankSEO toolkit covers all of it and shows you the evidence behind every result.
What it does not replace is Semrush's paid data. Advertising research, competitive PPC intelligence, a live backlink index and multi-client reporting are all part of the paid platform and stay there.
