Description

From the marketplace listing

Ask ChatGPT to check a web page. Five read-only tools: a one-page SEO check with a score, problems by area and the most serious problem with its fix; which AI crawlers a site's robots.txt allows, for 22 crawlers with the rule that decides; a redirect trace with each hop's status code; the HTTP headers that matter for search and security with a verdict on each; and a search snippet preview that shows where a title or description would be cut off. No account. We keep no record of the sites you check; public files we read, such as robots.txt, can sit in an edge cache for up to ten minutes. For site owners, marketers and SEO agencies. Limits: it checks one public page at a time, not a whole site; it reads what a crawler would see at that moment, so it cannot see a firewall that treats a real crawler differently; it does not track rankings or search volumes.
