The alternatives
FoundByChat
FoundByChat tells site owners when ChatGPT's search finds, cites or rewrites their pages. It checks ChatGPT search only, without competitor tracking or a visibility score.
You add your website and customer questions, and FoundByChat asks ChatGPT those questions with web search on every 2 hours as a user in the United States (English) or the Netherlands (Dutch). It records whether ChatGPT's search found one of your pages ("Found"), cited one in its answer ("Cited"), and the usual position of your pages among the search results. It lists your "Pages in ChatGPT's index" with the title and short snippet ChatGPT's search keeps, and emails you on "New in the index", "Snippet changed", or "No search results" (three checks in a row with no web results; the first check sets the baseline). It is free to start with Google or an email link (no password or card), with an English and Dutch interface and API keys.
The free GEO audit needs no account and allows 5 audits a day. It fetches your page with the OAI-SearchBot user agent, rebuilds the title and ~200-character snippet that ChatGPT's search keeps, looks the page up in ChatGPT and scores it out of 100 with a letter grade. It checks page response, bot protection, access for OAI-SearchBot, page size, text in HTML without JavaScript, title length, title and H1, menu or cookie text leaking into the snippet, the opening sentence, facts up front, meta description, JSON-LD, llms.txt, robots.txt rules for OAI-SearchBot, GPTBot and ChatGPT-User, noindex and the sitemap.
