tools.
A little lab of free, web based SEO tools I've made. Have a poke around. More get added as I make them.
indexability checker
Paste a URL and find out why it might not be indexed - HTTP status, redirects, the X-Robots-Tag header, the robots meta tag, canonicals and robots.txt, all in one pass.
→ check a URLai visibility audit
See what an AI crawler actually gets when it turns up at a page - extracted content, structured data, robots.txt AI directives, sitemaps, llms.txt and per-bot readiness.
→ audit a siterobots.txt tester
Fetch or paste any robots.txt, get every rule explained in plain English, then test whether a URL is allowed or blocked - and by exactly which rule, for the crawler you pick.
→ test a robots.txtsitemap finder
Lost track of your sitemap? Enter a domain and this hunts it down - reads robots.txt, probes the usual (and a few unusual) locations, tells a real sitemap from a soft-404, and shows whether it is an index or a plain url set.
→ find a sitemapseo bookmarklets
A set of one-click bookmarklets for quick on-page checks - headings, image alt text, schema, sitemaps and more. Drag one to your bookmarks bar; no extension, no account.

The lab keeps growing - I build these whenever a real problem needs a quick tool, so new ones land here as I make them. Got an idea for one you wish existed? tell me about it.
