Sites whose server turns away ChatGPT's search crawler
Every site on this list allows OAI-SearchBot or PerplexityBot in its robots.txt, yet its server refused a request carrying that crawler's user agent, while the same request as Googlebot, as Bingbot and as a normal browser was served. The owner usually has no idea, because the robots.txt looks fine. If your agency fixes AI search visibility, each row is a site with a problem you can show its owner, with the date it was tested.

Get 25 rows free
Pick a market and I will email you 25 sites from it with the same columns the paid list has, with the sites I have not written to first. One sample per address. Your address is stored with the request, and you get the sample plus at most one short follow-up asking whether it was useful. The email is sent through Resend, an email delivery provider.
The full list
Each plan gives you a private page. On the CSV plans you filter the list by CDN, CMS, Tranco rank band, date added, whether a contact page was found and whether I have written to the site, and by country on Pro and API, then download it. The country plans are sold only for countries with at least 10 sites on the list, and each shows today's count so you know what you are buying.
Country list: $29 once
One country's list as it stands today, as CSV with every column. The download works for 7 days, and nothing renews.
Starter: $49/mo
One country, including the sites the scan adds there every day, as CSV with every filter.
JSON feed: $49/mo
The whole list as JSON for your own tool: each site, which crawler its server refused, the test dates, CDN, server header, rank band and each test's history. Up to 48 requests a day. It leaves out the contact page, country and CMS columns.
Pro: $295/mo
Every country, no row limit, and a date-added filter so you can pull each day's new sites as CSV.
API: $495/mo
Everything in Pro, plus a JSON endpoint with every column and each site's full test history.
The monthly plans cancel anytime from Stripe's self-serve portal. The list is new (the counts above are the whole of it), so check the count for your country before you buy. Payment is handled by Stripe and your card statement will read LAST MINUTE DEALS HQ. After checkout you land on a page with your private list link, and I email that link to the address you pay with.
The columns
- host and refused_crawlers: which of OAI-SearchBot and PerplexityBot the server refused.
- first_seen, last_tested and times_tested: when the refusal was first and last seen.
- cdn and server_header: where the refusal most likely comes from, and so where the fix goes.
- cms, country_guess, hosting_network and tranco_rank_band: for picking the sites that fit your agency.
- contact_page: a contact page found on the site, when there is one.
- i_wrote_to_them_on: the date I sent the site a note about the refusal, if I did, so you can skip those.
How the test works, and its limits
- Each site is requested as OAI-SearchBot, as PerplexityBot, as Googlebot, as Bingbot (full user-agent strings) and as Chrome, from the same place within a few minutes. It is listed only when its robots.txt allows the AI crawler, the AI crawler request was refused, and the other requests were served.
- The requests come from an ordinary network address. A firewall rule that checks the crawler's real IP ranges would let the real crawler in, and this test cannot see such a rule. Treat a row as strong evidence of a user-agent rule, and confirm it in the site's firewall or logs before you tell a client what ChatGPT saw.
- Some owners block these crawlers on purpose. A robots.txt that says yes while the server says no is usually an accident, though not always.
- The country is a guess: the country domain first, otherwise the registry country of the hosting network, never for global clouds and CDNs, whose country says nothing about the site.
- The CMS comes from the homepage's generator tag and a few platform fingerprints, and is blank when nothing matched.
- A site drops off the list when its last test is more than 14 days old, until it is tested again.
- The sites come from the Tranco list, ranks 20,000 to 1,000,000, tested in batches several times a day. Adult, gambling and piracy sites are kept out by a keyword filter on the hostname.
What stays free
Checking one site stays free, with the checker or at /r/yoursite.com, and the 5,000-site census is open data under CC BY. What the plans sell is the list itself, kept fresh, and its filters.
