ChatGPT and other AI tools can't see my website

Work through the three causes in order. Access first, rendering second, content last, because fixing content on a page crawlers can't reach changes nothing.

The quick answer

There are three usual causes, in this order. A robots.txt rule blocks the AI crawler, your CDN blocks AI bots at the firewall (Cloudflare now does this by default on new zones, regardless of robots.txt), or your content only exists after JavaScript runs, which most AI crawlers never do. Check crawler access first, then rendering.

GigAI GEO Audit

One URL in, one AI-visibility report out: crawler access with Cloudflare detection, JS rendering, citability scored with published methodology, retrieval chunks, answer snippets and schema. Each finding linked to the free tool that fixes it.

AI Crawler Access Checker

Check whether GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot, Bingbot and every other AI crawler can read your site. Real RFC 9309 robots.txt matching with the deciding rule quoted, plus Cloudflare default-blocking detection. Free, instant, no signup.

JS Rendering Checker

See your page the way AI crawlers see it: without JavaScript. Fetch the raw HTML, count the words that survive, detect client-rendering framework markers, and diff against the rendered DOM to list exactly which content is invisible to GPTBot, ClaudeBot and PerplexityBot.

AI Crawler Log Analyzer

Drop a server access log and see which AI crawlers actually visit: per-bot hit counts, first and last seen, most-fetched pages, status-code health, daily trend, and the pages no AI crawler has ever touched. Parsed in your browser: logs contain visitor IPs and never leave your device.

AI Robots.txt Generator

Generate a correct robots.txt policy for every AI crawler (GPTBot, ClaudeBot, OAI-SearchBot, PerplexityBot and 11 more) with per-bot allow/block toggles and a plain-language line on what each choice costs. Free, in your browser.

How to fix it

Follow these steps and you'll have it sorted in a couple of minutes.

  1. 1

    Run a full audit

    Enter your URL in the GEO Audit. It checks crawler access, rendering, content and schema in one pass and orders the findings worst-first.

  2. 2

    Check crawler access

    The AI Crawler Access Checker gives a verdict for each AI crawler token and quotes the exact robots.txt line that decided it.

  3. 3

    Check for CDN blocking

    If you're behind Cloudflare, open Security then Bots in the dashboard. The AI-bots setting blocks crawlers before robots.txt is ever read.

  4. 4

    Check rendering

    The JS Rendering Checker counts how many words survive without JavaScript. If the number is small, your content is invisible to AI crawlers.

  5. 5

    Confirm with your logs

    Drop a server access log into the Log Analyzer. It's the only authoritative record of which crawlers actually arrived.

Common mistakes to avoid
  • Assuming a permissive robots.txt is enough. A CDN or firewall can reject AI crawlers before your file is read, and nothing in robots.txt reveals that.
  • Blocking every OpenAI bot to opt out of training. GPTBot trains models, but OAI-SearchBot and ChatGPT-User are what put you in ChatGPT's answers and send traffic.
  • Trusting analytics to show bot visits. Crawlers don't run JavaScript, so tools like GA4 can't see them. Only server logs can.
  • Rewriting content first. If crawlers can't reach or read the page, better copy changes nothing.
