AI Crawler Check
Fetches your site as each named AI crawler — OAI-SearchBot, PerplexityBot, Claude-SearchBot, GPTBot, ClaudeBot, Googlebot, Bingbot — and reports the HTTP status and robots.txt rule for each, separating the crawlers that decide citation from the ones that only collect training data.
Last Updated Check
Are you getting the SEO work you pay for? Google reads the last-changed date your sitemap reports for every page, and a site nobody has touched in months has nothing new for an AI answer engine to cite either. We lay those dates out as a work log — newest change first, pages changed per month, the longest run of months with nothing — so you can see whether your site is actually being worked on. If you pay an SEO agency, this is the record you were never sent.
Structured Data Check
Can an AI engine actually read your schema? Reads any page’s JSON-LD and reports whether each block can be parsed at all, what it declares, whether it carries what answer engines need, and whether your llms.txt exists and says anything. A block with one comment in it is invisible to every machine, and nobody notices.
Want to know whether AI actually recommends your business, not just whether it can read you? That is the $25 report. Comparing tools first? See the free-checker roundup.
