Why Blocking ChatGPT From Your Website Usually Costs You Customers

By Hamza Ali · WeProms Digital · November 8, 2026

Last updated: November 2026.

Last Ramadan, a Pakistani-American catering business two blocks off Devon Avenue in Chicago booked about $18,000 in iftar pre-orders (illustrative — substitute your own numbers). In October, a regular customer showed the owner a ChatGPT answer on her phone. The answer quoted a Devon Avenue halal caterer’s iftar buffet, described the menu, then printed a competitor’s phone number underneath. The owner’s first instinct was to block every AI bot from the restaurant’s website before sunset. That instinct would have made the problem worse, and this article explains why, using what the platforms actually announced in late October 2026 rather than the panic version circulating in owner WhatsApp groups.

The setup that caused the panic

On October 30, 2026, Google, Microsoft and OpenAI announced they plan to honor a shared robots.txt — the plain-text file on your website that tells automated crawlers what they may read control for AI training preferences, built on an Internet-Draft by Anthropic’s Kevin Kelley, as Search Engine Journal reported. The control is a normal robots.txt group under a policy token the article identifies as __usage_ai-training, with standard Allow and Disallow rules.

Read the fine print and the panic deflates. None of the three companies supports the control yet, according to their own announced timelines. Google says it will treat the shared opt-out as an opt-out of Google-Extended — the robots.txt rule that controls whether Google uses your content for AI training and AI answers grounding, and only when you have not set Google-Extended yourself. Microsoft will stop treating NoArchive and NoCache as training or grounding signals after March 1, 2027. So a small business that rushes a block into robots.txt today is pulling a lever that is not connected to the machine yet.

What blocking actually stops — and what it doesn’t

Here’s the thing. The word “block” hides two completely different activities, and the difference decides whether blocking helps you or quietly starves your business. AI training — companies feeding your pages into models that learn patterns. That is what the October 30 control governs. AI grounding — an AI answer service reading your live pages to answer a customer’s question right now. That is what sends a family to your iftar buffet instead of the shop down the street.

Blocking the training crawlers does not cleanly block the answers. Search Engine Journal’s reporting notes that Google’s own documentation says Google-Extended covers grounding in Gemini Apps, so a single “block everything” line can pull your menu out of AI answers while doing nothing about the training you objected to. The mechanics are crawling, not negotiation. Cloudflare measured crawler traffic rising 18 percent from May 2024 to May 2025, with OpenAI’s GPTBot activity up 305 percent in the same window, per Cloudflare’s crawler report. More reading means more chances your facts get repeated.

Think of ChatGPT as the largest aunty network on Devon Avenue that you will never meet. It repeats what it last read, it fills gaps with somebody else’s version, and it never forgets a wrong price until something fresher replaces it. You do not stop gossip by refusing to speak. You stop it by being the loudest, clearest, most recent voice in the room. Google’s John Mueller made the same point from the platform side in an October 29 interview: AI systems “build on SEO,” and he called AI crawling “another flavor of technical SEO.”

Why big publishers block and a Devon Avenue caterer shouldn’t

The blocking statistics you see quoted everywhere come from publishers, not restaurants. The Reuters Institute found that by the end of 2023, 48 percent of the most-used news sites across ten countries blocked OpenAI’s crawler, and 24 percent blocked Google’s AI crawler. An October 2025 arXiv study found 60.0 percent of reputable sites disallow at least one AI crawler, against 9.1 percent of misinformation sites.

Those publishers sell the content itself. Their calculus is licensing: if an AI company wants to train on a newsroom’s archive, the newsroom wants a check. A halal caterer sells iftar trays and shaadi packages. Your calculus is visibility: when a mother in Skokie asks ChatGPT who caters a 120-guest Eid dinner, you want your name, your per-head price and your booking number in that answer. The falsifiable claim in this article: for any local food business, staying readable earns more than the training value you withhold, and an owner who blocks broadly will see fewer AI mentions within two quarters. We see the same reflex every time a platform changes its rules — a Chicago sweet shop owner asking whether losing one AI recommendation should worry her is wrestling the same decision from the other end.

The hidden cost of opting out

What does the block actually cost you? First, freshness. Mueller’s interview described AI systems crawling with different intent — training runs versus fetching the latest content — so a blanket block removes you from the freshest reads, which are exactly the reads that decide what an AI answer says about your Ramadan menu this season. Second, consistency. Joss Merckaert of fifty-five put it on a MarTech panel this November: “You could have the best models. If you don’t have the right data in the first place, it’s going to be useless.” The same logic runs in reverse — if your per-head price, your serving sizes and your Eid pickup dates disagree between your website, your Google listing and your WhatsApp auto-reply, the AI will repeat whichever version it met last, as a Kuwait mandi restaurant learned the hard way with wrong Ramadan hours.

Count the free channel you would be muting. You already pay Grubhub, DoorDash and Uber Eats for every marketplace order, and you accept their rules to appear in front of their customers. An AI answer that names your caterer costs nothing per mention. There is a real operations sequence that separates the caterers who win that placement from the ones who read about it later: keep one page per service with plain prices, keep the listing facts identical everywhere, publish the Ramadan calendar eight to ten weeks before the month begins, and check what the AI actually says about you monthly. Ramadan 2027 is expected to start on Monday, February 8, 2027, subject to moon sighting, per published date forecasts, which puts the visibility cleanup window in early December 2026 — before the pre-order season, not during it.

The 15-minute check before you touch robots.txt

Most teams miss this. The fix starts with looking before changing anything. Run these five checks in order, once this month and once before Ramadan:

1. Open yoursite.com/robots.txt in a browser and read every line aloud. If you did not write it, whoever built the site did — and defaults sometimes block more than owners realize.
2. Search the file for GPTBot, Google-Extended and CCBot. If any appear under Disallow, ask who added them and why, and confirm the reason still stands.
3. Ask ChatGPT and Perplexity the question your customers ask: “Who caters halal Eid dinner near Devon Avenue?” Screenshot the answers with dates, and note which facts are wrong.
4. Verify that your iftar per-head price, serving size, delivery radius and booking number match across your website, your Google listing and your marketplace pages. Fix the mismatches before touching any crawl setting, because a blocked bot cannot read the correction either.
5. Write your policy in one sentence, date it, and put it wherever you keep business records — for example: “We allow AI reading of all public pages; we block nothing; we re-check answers quarterly.” A written policy beats an emotional one.

Blocking is a lever. Pull it with intent or leave it alone. The decision criterion is straightforward: if your revenue comes from selling your content, blocking protects the product; if your revenue comes from selling food, services or goods, readability is the product’s advertising. For the Devon Avenue caterer, the answer was not a block. It was a corrected buffet price, a fresh Ramadan page published in December, and a monthly screenshot habit — and by the next check, the AI answer was quoting her own number.

Frequently Asked Questions

Will blocking GPTBot remove my restaurant from ChatGPT’s answers?

Not cleanly, and not on your schedule. OpenAI’s answers draw on multiple sources, and the October 2026 shared opt-out is not live yet at any of the three announcing companies. Blocking a crawler removes your freshest content from future reads, which tends to make answers about you staler and more secondhand, not more flattering. Win the answer by keeping your pages readable and your facts consistent.

Does blocking AI crawlers hurt my Google search ranking?

No, and it does not help it either. Google Search indexing runs on Googlebot, a separate crawler from the AI-training crawler Google-Extended, per Google’s crawler documentation. Blocking Google-Extended does not remove your site from Search. The risk runs the other way: owners who edit robots.txt carelessly can block Googlebot by mistake, and that does deindex pages.

What is Google-Extended?

A special robots.txt rule that controls whether Google uses your content for AI training and for grounding answers in Gemini Apps. It is separate from the rules that govern normal Google Search. Google has said it will treat the new shared __usage_ai-training opt-out as a Google-Extended opt-out when a site has not set Google-Extended itself, so most small businesses never need to write either rule.

How do I check what ChatGPT says about my business today?

Ask it directly, the way a customer would: “best halal caterer near [your neighborhood],” then your business name by itself. Screenshot both answers with the date. There is a longer walkthrough in how to check what ChatGPT says about your business — written for Pakistan-market shops, but the method transfers line for line — and repeat the check monthly, especially before Ramadan.

What does WeProms charge to fix AI crawler settings?

No package prices appear in articles because scope varies: a single-location restaurant with one robots.txt file is a different job from a caterer with three marketplaces and a booking system. The audit call is free, and you get a written scope and price before work starts. Reach hello@weproms.com or the contact page.
