About these free SEO tools
This page collects the Keywords Everywhere tools that do actual SEO work, keyword research, link and authority analysis, site audits, and on-page checks, in one place. Each one is a focused, single-purpose tool rather than an all-in-one suite, so you can grab exactly the answer you need and move on.
They are genuinely free: there is no signup, no trial, and no credit card. A daily usage allowance keeps each tool fast for everyone, and signing in with a Keywords Everywhere API key raises those limits on paid plans. The keyword numbers (search volume, CPC, competition, and the 12-month trend) come directly from Google's Keyword Planner via the Keywords Everywhere API, the same source most professional SEO tools use. Authority, page rank, backlink counts, and spam scores come from Moz's public link index and our own crawl of the public web; traffic and difficulty figures are estimates computed from ranking positions and Google's search-volume data.
Frequently asked questions
Are these SEO tools really free?
Yes. Every tool on this page is free to use with no signup and no credit card. Some tools apply a daily usage allowance to keep them fast and fair for everyone; signing in with a Keywords Everywhere API key raises those limits on paid plans, but the core functionality is free for anyone.
Do I need an account to use them?
No account is required. You can run any tool right away. Optionally, appending your Keywords Everywhere API key to a tool URL signs you in and lifts the daily limits according to your plan, but that is never required for normal use.
What SEO tools are included?
The set spans the main areas of SEO: keyword research (search volume, CPC, keyword difficulty, SERP analysis), backlinks and authority (backlink and inbound-link checkers, domain authority, spam score, backlink gap), site and domain audits (traffic, top pages, competitors, subdomains), keyword discovery across Google, YouTube, Bing and more, and on-page SEO (title, meta description, H1, schema, redirects, content audits). Every card above opens a dedicated single-purpose tool.
Where does the SEO data come from?
Search volume, CPC, and competition come directly from Google's Keyword Planner via the Keywords Everywhere API, the same source most professional SEO tools use. Domain authority, page rank, backlink counts, and spam scores come from Moz's public link index and our own crawl of the public web. Traffic and ranking estimates are computed from ranking positions and Google's search-volume data.
Are these free SEO tools good enough for professional work?
Yes for most day-to-day tasks. The keyword numbers are Google's own, and the authority and backlink metrics come from established third-party indexes. As with any tool, treat computed figures such as estimated traffic and keyword difficulty as directional, and cross-check important decisions against your own analytics and Google Search Console.
Is there a limit on how much I can use them?
Each tool has a per-day usage allowance so that a few heavy users cannot slow the tools down for everyone. The free allowance is generous for typical use; if you need more, signing in on a paid Keywords Everywhere plan raises the daily cap. Every plan has a cap, higher tiers simply get a higher one.
