Free keyword research tool
Monthly search volume fetched live from Google Keyword Planner, estimated difficulty and intent. 10 lookups a month on the Free plan.
The four tools
Four free SEO tools, one free account.
Each one runs on the Free plan. Pick the job; the numbers underneath are the plan's real limits.
Free rank tracker
Track 25 keywords against your own Google Search Console data, by day, device and country.
Free SEO checker
Crawl up to 100 pages a month and run 60 technical checks, with the fix written out for each.
Free domain authority checker
MrKeyword Link Authority for any domain, from its own link index, with a confidence level and an as-of date.
Inside the workspace
Four tools, one visual language.
Each visual is a product surface, not decorative stock art: the surrounding copy remains searchable, accessible HTML.
The difference
Which free SEO tools read what, and why that matters.
- Data that needs no site of yours
- The keyword research tool asks Google Keyword Planner live every time you search, and the domain authority checker reads MrKeyword's own link index. They work for any keyword or domain, with no Search Console connection.
- Your own site's data
- The rank tracker and the SEO checker work on your site: one reads your connected Search Console property, the other sends a polite crawler to it. That is why they need a site you can verify.
- What free means
- Creating an account puts you on the Free plan straight away: it never expires, no card is asked for, and nothing is charged unless you choose a paid plan in Settings.

Read moreAre these SEO tools really free?
Yes. All four run on MrKeyword's Free plan, which never expires and asks for no credit card. Nothing is charged unless you choose a paid plan in Settings.
Why do I need an account?
The check runs inside a free workspace, so what you looked up is kept with its source and date, and the result opens in the full tool rather than as a single number on a web page.
What are the free plan's limits?
1 website, 25 tracked keywords, 100 audit pages and 10 keyword lookups a month. The pricing page compares them with the paid plans.
Are there free AI SEO tools here?
AI page audits and AI content briefs are on Pro AI, or available on any plan — including free — through the one-time 50 AI page audits pack for $5. Connecting your own AI assistant over MCP is included on every plan at no charge.
Where does the data come from?
Four places, and every metric names which one: your own Google Search Console and Bing Webmaster Tools properties, Google Keyword Planner (fetched live when you search), and MrKeyword's own crawler and link index.
Try the tools on your own site.
Free forever: rank tracking, keyword research, a site audit and domain authority. No credit card.
