Free SEO tools

A tool appears here only if you can use it without paying. That can mean a permanent free plan, a useful free tier, or a public tool that needs no account. Short trials do not count.

Free rarely means complete. Most of these cap crawl size, keyword volume, or exports, and the paid tier is where the tool earns its grade. The card grade reflects the whole product against its category, not just the free part. How grades work.
