Free SEO Tools

Which SEO tools a startup can use for free today, how many searches, projects or URLs the free plan covers, which data it gives, whether a card is needed and what the first paid plan costs, read from each tool's own page.

12SEO tools with a free allowance
7keyword and backlink tools
5site and ranking tools

Free allowances read on each provider's own pages, all checked on or after . SEO tools change their free limits often: confirm the terms on the tool's page before you rely on it for your keyword research.

SEO tools a startup can use for free today include Ahrefs (Free for verified sites), Google Search Console (Free service from Google), Semrush (Free plan, 10 reports a day), Bing Webmaster Tools (Free SEO/GEO tools and site insights), and Mangools (5 keyword lookups a day, free). Each of the 12 free plans below links to the tool's page that states it, with its main limit, which data it covers, whether a card is needed and what the first paid plan costs.

Search is how most startups get found without paying for every visitor. Google and Bing give their own search consoles for free, and the major keyword, backlink and site audit tools all have a free plan or a trial.

The headline rarely tells you how far it goes. A free plan can allow a handful of searches a day, one project or a few tracked keywords, or give full data only for sites you verify you own. Each tool below shows what is free, its main limit, which data it covers, whether a card is needed and what the first paid plan costs, quoted from the tool's own page with the date we read it.

Which tools we picked and the order they appear in are our editorial choices; the terms are the providers'. Some of these providers pay us a referral commission when someone signs up through our link: those links are labeled, and they play no part in which tools are listed or where.

Methodology

How this comparison is built

The list covers SEO tools a founder can use for free today without applying to a program. The order and the "best for" notes are our editorial reading of each tool's terms. Every term comes from the tool's own pricing or help page on the date shown, never from a third-party list; follow each link for the full conditions. A cap on daily searches or tracked keywords, or data only for your own verified site, can matter more than the headline, so the comparison quotes them wherever the tool states them. Some of these tools pay StartupPerks a referral commission, and their links are labeled as referral links; that decides neither whether nor where a tool appears, and no tool pays for a placement on this page.

StartupPerks is a comparison tool and is not endorsed by the programs it lists. It is a referral partner of some providers, and those links are labeled where they appear. AITraining.jobs and Founden are run by the same company as StartupPerks: their listings are free, ranked by the same rules as every other program, and labeled "Same owner as StartupPerks" wherever they appear. Values and eligibility are aggregated from each provider's public pages and can change or be incomplete. Always confirm the current terms and your eligibility on the provider's own page before applying.
