The Hidden Code That Tells ChatGPT About Your Business

When you ask ChatGPT about a plumber in your neighbourhood, it pulls information from somewhere. You might assume it's reading your web browser history or searching the internet in real-time. But what's actually happening is far more interesting — and far more fixable for your business.

Every website has invisible code running underneath its visible text and images. This code tells AI systems like ChatGPT exactly what your business does, where you're located, what you charge, and whether customers trust you. Most small business owners have no idea this code exists. And if it's missing or incorrectly set up on your website, AI platforms simply won't recommend you — even when someone's actively searching for what you offer.

The good news is that once you understand what signals AI looks for, you can add them to your website in an afternoon. This isn't about fooling algorithms or gaming the system. It's about speaking to AI in the language it understands, so it can confidently point potential customers your way.

What is this hidden code and why does it matter?

The hidden code is called schema markup, or structured data. Think of it like a label on the back of a product at the supermarket. The visible side shows a nice image and marketing copy designed for humans. The back side — the label — is pure information in a standardised format: ingredients, nutritional values, warnings, manufacturer details.

Your website works the same way. Humans see your homepage with your brand colours, friendly photos, and persuasive copy. AI systems, though, are looking for the label. They want your business name in a specific format, your address broken down by street and postcode, your phone number with the country code included, your opening hours in 24-hour notation.

Without schema markup, AI has to guess what your business does. It reads your website like a person skimming a messy pile of printed pages, piecing together clues. With schema markup, AI knows for certain. The difference is enormous. One feels like being recommended by someone who's done their homework. The other feels like a lucky guess.

Imagine you've prepared a folder about your business: one page lists your exact services, another shows customer testimonials, a third explains your qualifications, another lists your opening hours. Now imagine handing that folder to someone who wants to recommend you to their friends. They can instantly understand what you do and confidently suggest you. Without the folder — without that structured information — they're guessing based on fragments of conversation.

The seven signals AI platforms look for on your website

Business name, address, and phone number

Your contact details must be consistent and machine-readable across your entire website. "Machine-readable" means AI can extract them reliably — not hidden inside an image, not buried in a PDF, not in a format that varies from page to page. Your postcode should be consistent. Your phone number should include the country code.

Inconsistent contact information is one of the most common problems. Your footer says one address, your contact form says another, and your About page lists a different phone number. AI systems see this confusion and lose confidence in recommending you.

What services or products you offer

Don't list your offerings as vague marketing language. Instead of saying you offer "premium solutions for modern businesses", say you offer website design, SEO consultation, and email marketing setup. Be specific. Be concrete.

AI platforms are looking for explicit service lists so they can match you to specific customer questions. When someone asks ChatGPT "I need help with SEO in Manchester", the AI needs to know you actually offer SEO services in your service area — not guess it from your tagline.

Your service area

Where do you operate? If you're a plumber in Bristol, say Bristol. If you cover Bristol and surrounding areas, list them. If you're national or international, be clear about that too.

Location signals matter enormously for AI recommendations. An AI system recommending you to someone in Edinburgh when you only work in London helps no one. Being explicit about your service area prevents that mismatch.

Opening hours

When are you available? Not just "Monday to Friday" but specific opening and closing times in a structured format. This seems basic, but many websites skip this entirely or only mention hours in passing text.

AI uses your opening hours to help customers know when they can contact you. Without this information, AI might recommend you at inconvenient times or suggest you're always available when you're not.

Customer reviews and ratings

Third-party reviews carry enormous weight for AI systems. They're proof that real customers trust you. A business with genuine five-star reviews from verified customers will be recommended far more confidently than one with no reviews, even if both offer identical services.

Make sure your review profiles — Google, Trustpilot, industry-specific platforms — are linked from your website in a way AI can recognise. Don't just mention them in text; structure them so AI systems can extract the ratings and review counts.

Credentials and experience

How long have you been in business? What qualifications do you hold? Are you a member of any industry bodies or professional associations?

This information builds authority. AI systems use credentials to assess confidence in recommending you. A business that's been operating for fifteen years and holds relevant certifications looks more trustworthy than one with no background information.

Clear answers to common questions

What do people ask you repeatedly? Write FAQ content that directly answers those questions in plain language on your website.

AI systems use FAQ sections to understand what problems you solve and how you explain your services. Good FAQ content gives AI better material to draw from when recommending you. AI My Site checks all seven of these signals for your website and tells you exactly which ones are missing or broken — with step-by-step instructions to fix each one.

Common mistakes to avoid

• Having your address only as an image or in a logo. AI can't read images, so it won't find your location information.

• Listing services as trendy buzzwords instead of specific offerings. Be concrete, not creative. Say "tax preparation" not "financial optimisation".

• Assuming your website builder handles structured data automatically. Most don't, or they do it poorly. Check your website's actual code.

• Never testing what AI actually says about your business. Search for your business name in ChatGPT, Claude, or Gemini. See what information comes back. If it's wrong or missing, you've found your gaps.

How quickly can you fix this?

Most of these changes take an afternoon to implement. You don't need to hire a developer or buy expensive software. Your website builder probably has a way to add this information — either through a settings panel or custom fields.

Results take longer. Four to twelve weeks is typical before AI platforms start recommending you with confidence based on your updated information. This is because AI systems need to re-scan your website, verify the information, and update their internal models. It's not instant, but it's worth the wait.

Start with the basics: business name, address, phone number, services, and service area. These signals make the biggest difference and take the least time to implement. Then add FAQ content and ensure your review profiles are linked. Check your AI readiness score to see where you stand right now.

The invisible code running underneath your website is already influencing whether AI recommends you. The question is whether that code is working for you or against you. Once you know what signals matter, you can add them in an afternoon and watch AI confidence grow over the coming weeks.
