Do small-business websites block ChatGPT?

Almost never. 0% of the 512 sites we checked block AI search crawlers such as OAI-SearchBot, PerplexityBot or Claude-SearchBot in robots.txt, and only 2% hide their text behind scripts that many AI crawlers don't run. AI tools can read these sites; the problem is what they find.

What do AI assistants look for on a business website?

Short, direct answers to the questions customers ask (what you do, where, how much, how fast), plain facts about the business in structured data (name, address, phone, hours, area served), and enough text to show what the business is good at. Those are what get quoted or recommended.

What is llms.txt, and do I need one?

llms.txt is a newer, optional plain-text summary of a site written for AI tools. 29% of the sites we checked already have one, mostly because builders such as Wix, Duda, Shopify and GoDaddy now create it automatically. It's cheap to add, but not every AI tool uses it yet, so answers on the page matter more.

What's the quickest fix?

Add five to eight real customer questions with one- to three-sentence answers to the home page, each as a heading followed by its answer, and mark them up as an FAQ. Then make sure the business name, address, phone and service area are in structured data. Our free SEO & AI search check writes the markup for you from your own page.

Can ChatGPT and other AI assistants read small-business websites?

Yes, they can read them, but there’s little to quote. Of 512 small-business websites we checked, none block AI search tools. But 87% don’t answer a single customer question on the home page, and 44% don’t describe the business in the structured data AI assistants read for names, addresses and phone numbers. When ChatGPT or Google’s AI Overviews look for a business to recommend, those sites give them very little to work with.

Can AI crawlers get in?

0%block AI search tools (ChatGPT search, Perplexity, Claude) in robots.txt
2%show almost no text until scripts run, so most AI crawlers see a nearly empty page
2%tell search engines not to list the home page at all

Access isn’t the problem. Nearly every site is open to AI tools.

What do AI tools find once they’re in?

87%answer no customer questions on the home page, the short answers AI assistants quote
62%have no headings phrased as questions, the way people ask AI assistants
44%have no structured data describing the business itself (name, address, phone)
28%have very little text on the home page for an AI to go on
23%have no description written for Google to show under their name
17%don’t show a phone number or address that AI tools can read on the home page
9%do answer questions, but without the FAQ markup that lets search and AI lift the answers directly

Data: Phulax LLC's automated checks of 512 Wisconsin small-business home pages in October 2026, from chamber of commerce and trade-association member directories. No business is named.

Is llms.txt catching on?

Faster than we expected: 29% of the sites already serve an llms.txt file, a plain summary written for AI tools. Most of them didn’t write it themselves: nearly every Wix, Duda and Shopify site in our sample had one, and most GoDaddy builder sites, because those platforms now create it automatically. Far fewer WordPress, Squarespace and custom-built sites have one. It’s a useful extra, but it doesn’t replace answers on the page itself.

Why does this matter for a small business?

More people now ask an AI assistant “who’s a good plumber near me?” instead of scrolling search results. The assistant names a few businesses and quotes a line or two about each. A site that answers common questions plainly and states its basic facts in structured data gives it something to quote. One that doesn’t leaves the assistant to guess, or to recommend someone else.
