Free single-purpose SEO tools

Each tool runs one deterministic check and tells you the verdict. Start with the file your AI citations depend on, then work down the list.

Where to start

Start with the files machines read first: the llms.txt your AI citations depend on, the robots.txt every crawler fetches, then the JSON-LD your rich results are built from.

Then check single pages the way ranking sees them: canonical self-reference after redirects, the redirect hops spending your crawl budget, the meta snippet searchers actually see, and the favicon file behind the tag.

Then zoom out to sets: the hreflang cluster whose members must point at each other, the sitemap that lists everything, and finally whether the latest Google update moved your pages.
