Free SEO tools
Every tool is free, with no account, no email and no subscription. The generators and counters run in your browser, so they're unlimited and nothing you type leaves your device.
Which SEO tool should I start with?
Start with the free SEO check on your most important page – it covers everything below in one report. Then run the website audit to catch site-wide problems, and turn on weekly monitoring so nothing breaks unnoticed.
Are these SEO tools really free?
Yes. No sign-up, no trial and no limits beyond fair-use rate limits that stop abuse. XKey is paid for by IceWork, who build websites, as a useful free service.
Do the single-topic tools run a different check?
The checkers for speed, schema, sitemaps, security, mobile and local SEO run the full check and open your report at that section, so you never miss a bigger problem elsewhere on the page.
