Should you let AI read your website, or block it?
If you run a local service business, you should let AI read your website, not block it. The advice to “block the bots” that circulates online is aimed at large publishers protecting paywalled archives, and for a plumber, an HVAC shop, or a roofing crew it is exactly backwards. Answer engines like ChatGPT, Perplexity, and Google’s AI Overview can only name you in an answer if they are allowed to read you first. Being named in that answer is how a customer finds you, so blocking the readers blocks the customers.
Below is who should actually block, who should not, and the small set of files that tell an AI it is welcome.
Is letting AI read my website bad for my business?
For a local service business, letting AI read your website is good for your business, not bad. The fear behind the question is borrowed from a different industry. When a news site or a research publisher blocks AI crawlers, it is protecting an archive it sells access to. Its product is the writing itself, so a machine that copies the writing and answers the question without sending a reader to the page is a direct loss of revenue. That is a real problem for them, and blocking is a reasonable defense.
Your website is not that. Your product is the work you do in person, the boat you repair or the drain you clear, and your website is the sign that points a customer to you. When an answer engine reads your site and tells someone “this shop services that brand, here is the phone number,” it has done the exact job a sign is supposed to do. The reading is the point. You can read more about why a machine has to be able to read you at all in why AEO matters now.
Who should block AI crawlers, and who should not?
Publishers with monetized archives should consider blocking AI crawlers; local service businesses should not. The dividing line is simple: does the words-on-the-page content earn you money by itself, or does it earn you money by sending a person to a service you perform?
- Should block, or at least control it: news organizations, paywalled research, subscription databases, stock photo libraries, anyone whose business is selling the content directly. A machine that absorbs the archive and answers from it can take the sale.
- Should not block: local service businesses, contractors, repair shops, medical and dental practices, restaurants, anyone whose website exists to bring a nearby customer through the door. For you, an AI that cannot read your site simply recommends a competitor it can read.
If you are in the second group, which almost every owner-operated service business is, blocking AI crawlers gives you all of the downside of being invisible in the answer and none of the upside the publishers are protecting.
How do I tell AI crawlers they are welcome?
You welcome AI crawlers with three small declarations: a robots.txt that names them and allows them, a plain statement on your site that AI use is permitted, and a website a machine can actually read. The first two are short text files. The third is the real work.
Name the major AI crawlers in robots.txt and allow them. Your robots.txt is a plain text file at the root of your site that tells automated visitors what they may read. A default file often stays silent about AI crawlers, and silence is ambiguous. Naming them removes the doubt. A welcoming file lists the known answer-engine crawlers by name, grants them access, and can add a Content Signal line that openly permits AI use:
User-agent: *
Allow: /
# Content Signal: permit AI training, search, and AI answer use
Content-Signal: ai-train=yes, search=yes, ai-input=yes
User-agent: GPTBot
Allow: /
User-agent: OAI-SearchBot
Allow: /
User-agent: ChatGPT-User
Allow: /
User-agent: ClaudeBot
Allow: /
User-agent: anthropic-ai
Allow: /
User-agent: Claude-Web
Allow: /
User-agent: PerplexityBot
Allow: /
User-agent: Google-Extended
Allow: /
User-agent: Applebot-Extended
Allow: /
Sitemap: https://yoursite.com/sitemap.xml
Those names are the crawlers behind ChatGPT and ChatGPT search, Claude, Perplexity, and Google’s and Apple’s AI products. Listing them is an explicit invitation rather than a maybe. Vendors do add and rename crawlers over time, so it is worth checking the list stays current. Add a Sitemap: line too, pointing at your own sitemap, so a crawler that respects robots.txt also gets a clean map of every page.
State plainly that AI use is allowed. Beyond robots.txt, you can publish a short, readable declaration that you welcome AI systems to read and cite your content. Some sites do this with an llms.txt file, a plain summary of what the business is and where the key pages are, written for a machine to lift. The instinct it reflects matters as much as the file: you are removing every reason for an engine to hesitate before quoting you.
Make the site readable in the first place. Permission is worthless if the content is locked inside images, sliders, or scripts a machine cannot parse. The deeper version of this lives in is your website ready for AI, but the short form is: put your services, your service area, your hours, and the questions customers actually ask into real text on the page, and keep your name, address, and phone identical everywhere, the discipline covered in why a business that clearly exists can still be invisible.
There is one recent change that makes the welcome stance more urgent. Google retired the manual Questions and Answers section of the Business Profile in late 2025, replacing it with an AI-generated answer drawn from the profile and its reviews. You no longer hand-write those answers. The machine writes them from what it can read, which is one more reason to let it read everything you would want a customer to know.
The short version
For a local service business, you want AI to read your website, because being named in the answer is how a customer finds you. The “block the bots” advice is built for publishers who sell their archives, and it is the wrong move for a shop whose site exists to bring people through the door. Publishers with monetized content should consider blocking; local service businesses should not. Welcome the crawlers by naming them in robots.txt and allowing them, stating plainly that AI use is permitted, and putting your real information in text a machine can read. An answer engine that is allowed to read you is an answer engine that can recommend you.
