ChatGPT bot access test
Updated
Enter a URL and Leadee checks robots.txt for OpenAI's three documented bots — OAI-SearchBot, ChatGPT-User and GPTBot — then live-fetches the homepage with each bot's own user agent (where OpenAI publishes one) to tell a robots.txt rule apart from a firewall or CDN silently blocking the bot. Not affiliated with or endorsed by OpenAI.

What this checks
- robots.txt rule for OAI-SearchBot, ChatGPT-User and GPTBot
- A live fetch with each bot's own user agent (OAI-SearchBot, ChatGPT-User), to catch a WAF/CDN block robots.txt would not show
- Which bot is blocked, and whether the block is robots.txt, a firewall, or neither
Example result
1 of 3 blocked
- OAI-SearchBot: allowed
- ChatGPT-User: blocked by firewall (robots.txt allows it)
- GPTBot: allowed
How to read your result
A bot blocked by robots.txt is a policy choice you made (or inherited) and is simple to change; a bot blocked by a firewall/CDN even though robots.txt allows it is usually invisible until a live fetch catches it — that row needs an allow-list change at the firewall or CDN, not in robots.txt.
Limitations
The live fetch spoofs each bot's User-Agent header from Leadee's own server — a real firewall often verifies a bot by IP range instead, so a "not blocked" result here is an indicator, not proof the real bot gets through, and a "blocked" result from an IP-only firewall may not show up here at all. GPTBot is training-only and is not live-fetched (see the FAQ).
How to fix what it finds
- Enter the URL you want to check.
- Read the robots.txt verdict and the live-fetch result for OAI-SearchBot and ChatGPT-User.
- If a bot is blocked by robots.txt, update the rule; if blocked by a firewall/CDN, allow-list that bot there instead.
- Re-run the test after you change anything, to confirm the block is gone.
Questions
Is this tool affiliated with or endorsed by OpenAI?
No. Leadee is not affiliated with, endorsed by, or sponsored by OpenAI. OAI-SearchBot, ChatGPT-User and GPTBot are OpenAI's own bot names, documented at developers.openai.com/api/docs/bots.
What does each of the three bots do?
OAI-SearchBot crawls to surface sites in ChatGPT's search features. ChatGPT-User fetches a page in real time when a ChatGPT user (or a Custom GPT) asks for it. GPTBot is a training crawler, unrelated to any single live ChatGPT answer — blocking it is a legitimate policy choice, not a visibility problem.
Why is GPTBot not live-fetched like the other two?
GPTBot only trains future models — it is never the bot that fetches a page while answering a live ChatGPT question, so there is no "can it reach me right now" moment to probe; its row only carries the robots.txt verdict.
My robots.txt allows all three bots — why would one still be blocked?
A firewall, CDN or bot-management rule (the kind that blocks "unrecognized" user agents by default) can block a request before it ever reaches the server robots.txt is served from. The live fetch catches that case; the fix is an allow-list rule at the firewall/CDN, not a robots.txt change.
Can GEO guarantee results?
No. AI answer engines change their output frequently, and no vendor — including Leadee — can guarantee a ranking or a mention. Leadee publishes confidence intervals on every metric so you can see how much a result can vary run to run.
How does Leadee measure AI visibility?
Leadee runs your prompt set against each AI engine on a weekly to daily schedule, depending on plan, through official vendor APIs (OpenAI, Gemini, Perplexity, Anthropic, DataForSEO) — never by scraping consumer chat interfaces — and reports mention rate, citation rate, average position, share of voice and sentiment with a 95% confidence interval.
