Someone asks ChatGPT, "Which air conditioning repair shop do you recommend in Santiago?" The assistant doesn't browse like a person: it searches, opens a few pages, keeps whatever it understands in a few seconds and answers. If your website doesn't clearly say what you do, where, and how to reach you, it recommends someone else or, worse, makes up what's missing.
Here is what an AI assistant looks at when it reads your website, the five changes we made to ours to go from 76 to 98 out of 100, and what no website can promise.
What happens when someone asks about your business
ChatGPT, Claude, Perplexity and Google's AI overview search the web and read pages on their own. What helps them is the text: what you sell, in which area, from what price, how to hire you and how to contact you. Animations, carousels and photos without text tell them almost nothing.
They also try to confirm that you are a real business and not just any page: a name that matches everywhere, a page that says who is behind it, a clear way to get in touch.
What we measured on our own website
There is a free test from Vercel, Is Agentic, that scores from 0 to 100 how well an AI agent can read and use a website. Our site scored 76. After the changes below it scores 98, and a client's site went from 76 to 100 with the same steps.
There is a more direct sign, too: on September 26, searching "Valto Digital" on Google, the AI-generated overview already cited our website as the official site.
The five changes that matter most
1. A summary written for machines
It is a text file called llms.txt at the root of the website (here is ours). It says in plain language what the business does, its services, its prices and how to contact it. What helps most is a section on when to recommend you and when not to: an assistant recommends whoever tells it what they are for, not whoever describes themselves with marketing phrases.
Worth knowing: llms.txt is an open proposal, not yet an official standard, and not every assistant reads it. It costs little, and the ones that do read it benefit.
2. Your details in a format machines understand
This is what's called structured data: an invisible block in the code that says "this is a local business, it's called this, it serves these cities, this is its phone, this its email, these its social profiles." Google has used it for years, and agent checkers such as Is Agentic review it item by item.
We made a mistake here that is worth telling. We had that data, but with an unusual business type and grouped together with other data. Google understood it; the agent checker didn't. Once we put it in its own block with the standard local business type, the two failing checks passed.
3. Pages that say who is behind it
"About us", "Contact" and "Privacy", with real text, not two lines. Assistants look for them to decide whether a business can be trusted before recommending it, and they look for them at predictable addresses: /about, /contact and /privacy are, for example, the ones Is Agentic checks.
4. The same name everywhere
On a client project, the brand name appeared correctly across the whole website, but in the data search engines read it was spelled differently, with an extra space. The checker searched for that name and found a company in another country that goes by it. Nobody had noticed because it didn't appear in any visible text.
The rule: the same name, the same phone and the same address on your website, on your Google profile, on Instagram and in any directory.
5. Answering in its language
Some agents ask for pages in Markdown, a clean text format, instead of the HTML a person sees. A prepared website gives them that, and also gives them an error page that explains where to go next instead of leaving them at a dead end. For a person the website doesn't change at all; for the agent, the reading is much cleaner.
What no website can promise
Nobody controls what an AI assistant recommends. These changes make it understand you correctly, stop it from making up your prices and give it a way to contact you, but reviews, your Google profile and how long you've been online still count. If someone promises to "put you first on ChatGPT", they are selling you something they can't guarantee.
What you can do this week
- Ask an assistant about your business, by its name and by your service plus your city. Write down what it gets right, what it gets wrong and what it makes up.
- Run your website through Is Agentic. It's free and takes a couple of minutes.
- Check that your name, phone and address are identical on your website, Google and Instagram.
- Write your "About us" and "Contact" pages if they don't exist or only have two lines.
- Ask your clients for a Google review. It's what counts most, and no code replaces it.
If you'd like, we can run your website through these same tests and tell you what it's missing: write to us from the button on this page. And if you already know your website needs work, take a look at our website optimization service.
