Robots.txt and AI: the complete guide to getting cited by ChatGPT, Gemini and Perplexity
Which AI crawlers to allow or block, how to opt out of training without leaving ChatGPT, the new __usage_ai-training token and 3 robots.txt files to copy.
BotRank study, November 2026. In late October, Google AI Overviews cited veepeec.com as a source. One extra "c", Veepee's logo and colors. Then a form asking for your phone number and password. The real site is veepee.fr. This is not an isolated case: by analyzing the sources AI engines cite for the brands we track, we identified at least 144 fake websites. The phenomenon is rare. But it is real. And it mostly affects ChatGPT.
The domain veepeec.com looks almost exactly like the site of the French flash-sale brand. Only one letter sets it apart. The page shows Veepee's logo, colors and login interface. It asks for a phone number and a password: it is a phishing page, built to harvest customer credentials.
On October 30, 2026, Google AI Overviews listed it among its sources in an answer about online fashion. On November 9, the page was still online. Anyone clicking that source lands on an exact copy of Veepee's login page.

Every day, BotRank asks the main AI engines (ChatGPT, Gemini, Google AI Overviews, Perplexity, Mistral…) the questions customers ask about the brands we track. For each answer, we record the cited sources.
We analyzed 2.5+ million answers, 20+ million citations and 320,000 distinct domains.
We isolated the domains that reuse a well-known brand name without being its official site. Six patterns keep coming back:
Every suspicious domain was checked individually:
Each domain received a verdict, backed by evidence. A domain is only labeled a "confirmed fake" if we saw the copy, the fake store or the phishing page. It is labeled a "probable fake" when its content can no longer be observed (offline, blocked, hidden) but every clue points the same way: a hijacked brand name, a recent registration, the same registrar and date as proven fakes.

144 fake sites among 257 suspicious domains
Verdict after checking each suspicious domain cited by AI engines for the brands tracked by BotRank.

This is the largest group. The fake domain displays the brand's real website, copied live. Example: france-literie.live is an exact replica of the site of France Literie, a French bedding retailer. All 555 links pointing to france-literie.fr in the real site's code are automatically rewritten to france-literie.live. The same mechanism shows up on terdav.life (Terres d'Aventure), bergamotte.mom, loacker.mom and neuhauschocolates.pro.
These clones rarely come alone. On July 16, 2026, eight .mom domains were registered on the same day, with the same registrar, for eight brands that have nothing to do with each other. Brands do not work this way: it is the signature of a single operator.
Other domains display a store in the colors of a well-known brand: coupons, "free worldwide shipping", fake showcase sites. barebellsus.com poses as a Barebells store, rxbarshop.com reuses RXBAR, godivaofficial.shop imitates Godiva. Four showcase sites named after KIND, Barebells, Fisherman's Friend and Quest Nutrition share the same template and the same servers.
This is the rarest group, but the most dangerous. Besides the fake Veepee, tonyschocolonely.live is flagged by Cloudflare as a phishing site.
One detail says it all. Maxi Zoo's real website includes copy protection: when it is displayed on any domain other than maxizoo.fr, a script sends the visitor back to the real site. So a human who lands on maxizoo.mom gets redirected.
But the bots that crawl the web to feed AI engines generally do not run this kind of script. They see the copy, with the brand's full content. And they can cite it as a source.
More broadly, a perfect clone is hard for a bot to tell apart from the original: same content, same text, same images. Only the domain name changes. Recent extensions (.mom, .live, .pro…) and freshly registered domains are not enough, on their own, to rule a source out.
Not all AI engines are equally exposed to fake sites. ChatGPT produces 31% of the answers we analyze but accounts for 91% of fake-site citations. Gemini, which produces as many answers, accounts for only 2%.

Each engine's share of the answers analyzed and of fake-site citations (confirmed or probable).
Source: BotRank.ai study, data as of November 9, 2026. 2.56 million answers analyzed, 5,366 fake-site citations. Copilot, Claude and AI Mode, under 1% of answers, are not broken out.
Our data cannot explain this gap with certainty. One hypothesis: the way each engine selects its sources. Gemini and AI Overviews rely on Google's index, which has long filtered out much duplicate content. ChatGPT relies on its own search tools, which seem to filter these copies less.
Proportion matters. Fake sites remain the exception in AI answers.

But a single answer is enough to send a customer to a copy of a brand's website, or even to a page that steals their credentials. And when we checked, in early November 2026, about half of the fake sites we identified were still online.
One important caveat: 144 is a floor. We only checked domains flagged as suspicious using the patterns described above. Fake sites built differently will have slipped through.
A domain that looks like a brand is not necessarily a fake. More than a third of the suspicious domains turned out to be legitimate:
Hence our rule: no domain is called a fake without observed evidence.
Yes. Out of 320,232 domains cited by AI engines for the brands tracked by BotRank, we identified at least 144 fake sites: clones of brand websites, fake online stores and phishing pages.
ChatGPT, by far. It accounts for 91% of fake-site citations while producing only 31% of the answers analyzed. Relative to volume, that is about 6 fake-site citations per 1,000 answers, versus less than 1 for Perplexity and about 0.1 for Gemini and AI Overviews.
No. Fake sites account for less than 0.05% of cited domains and about 0.03% of citations. But the risk is real: a single answer can send a user to a cloned site or a phishing page.
Check the site's exact address before typing anything: an extra letter, an unusual extension or a word added to the brand name should raise a flag. When in doubt, go to the brand's official address rather than the suggested link.
By tracking the sources AI engines cite on the questions that concern it. That is what BotRank measures, engine by engine.
