As answered by people managing Data Protocol and IsItIndexed.
IsItIndexed's answer:
Most SEO tools tell you whether a page is indexed. That's a yes/no answer, and if you already know your page isn't indexed, it tells you nothing. IsItIndexed runs 13 diagnostic checks to figure out why Google won't index your page and what to fix first. It also checks whether AI platforms like ChatGPT, Claude, and Perplexity can find and cite your content. No other single-URL tool combines Google indexability diagnostics with AI visibility checks.
IsItIndexed's answer:
IsItIndexed's answer:
Site owners, solo founders, bloggers, and freelance SEOs who are stuck in "Crawled, currently not indexed" limbo in Google Search Console. People who know something is wrong but don't have an SEO team to diagnose it. Also useful for anyone who wants to check whether AI search engines can actually find their content.
IsItIndexed's answer:
Google's June 2025 core update pruned an estimated 15-20% of the index. More pages than ever are stuck in "crawled but not indexed" and existing tools only check whether you're indexed, not why. At the same time, AI crawlers showed up and nobody had tooling to check visibility across those platforms either. I built IsItIndexed to close both gaps in one scan.
