Blocked crawlers do not make you look bad. They make you absent.

What this tool checks

AfterLaunch fetches your site the way the AI crawlers do and scores what they can actually get to. That covers whether your robots.txt allows the crawlers that feed ChatGPT, Claude, Perplexity and Google, whether your pages return readable content without needing JavaScript to render, whether an llms.txt file is present, and whether the basic structure a machine reads (titles, descriptions, structured data) is in place.

The result is a score out of 100 with the highest-leverage fix first. The full breakdown, unlocked with an email, lists every check with what it found and the exact change to make.

Why AI crawlability matters

AI assistants answer questions about your category by reading the web. If their crawlers are blocked at your robots.txt, or your pages only render content client-side, the systems deciding whether to mention you are working from a blank page. Being unreadable does not make you look bad; it makes you absent.

Crawlability is the cheapest layer of AI visibility to fix. Most of the failures are one-line changes: an allow rule, a meta description, a static rendering of the content you already have. This check tells you which of those lines apply to you.

Common questions

Which AI crawlers does the checker test for?

The check reads your robots.txt rules for the crawlers behind the major AI assistants and search engines, including the bots OpenAI, Anthropic, Perplexity and Google use to fetch web content. It then fetches your homepage the way those bots do and scores what comes back.

Does a good score mean AI assistants will recommend me?

No. Crawlability is the entry ticket, not the win. A readable site is necessary before any AI system can cite you, but being recommended also depends on what your pages say and on how the rest of the web describes you. The free Growth Snapshot measures that wider picture.

Is the check safe to run on any site?

Yes. It makes a small number of plain HTTP fetches, the same as a normal crawler visit, and changes nothing on the site. You can run it on your own product or on any competitor.

What does it cost?

Nothing. The score and top fix are free with no signup. The full per-check breakdown unlocks with an email address. No card, no trial starts.
