What we measure when we do GEO in Sherbrooke
We ask the same questions every month and write down, for each answer, if your company is in it, how high up and which source is cited.
More than 200 clients trust us.
GEO (generative engine optimization) means making sure AI assistants know your company well enough to recommend it. If ChatGPT never names you, the person asking never hears of you. We help businesses in Sherbrooke appear in answers from ChatGPT, Gemini, Perplexity and Google.

SherbrookeCanadaWorldwide
Some 130,000 people live in Sherbrooke. It is part of Quebec. There are 10 cities in Quebec with their own page here.
When AI cannot find details about a local business, it recommends one from elsewhere. A few clear pages, a well-kept business profile and recent reviews change that answer. We work from Murcia, in Spain, usually 6 hours ahead of Sherbrooke. Meetings are by video call and in English. We offer the same in Trois-Rivières, Longueuil and Montréal.

What we do, depending on your sector
Before asking for a quote, many people ask AI what a renovation costs and who to call. We publish your guide prices and your finished jobs so it has something to work with.
AI gets asked about neighbourhoods, prices and agencies people can trust. Good area guides, written with your own data, make you a source it can quote.
Parents and students compare tutors by asking AI. We publish results, timetables and prices clearly so it has something to recommend you with.

We measure before we change anything. The starting picture shows the answers you appear in and, for the ones that leave you out, who is there in your place.
The starting point, in writing: answers you are in, answers where your brand is missing and the sources AI used for each one.
People do not write to AI the way they type into Google. They use long sentences with context, and you need to know which ones your customers use.
AI cites what it can summarize without getting it wrong. We turn your pages into direct answers, with your own figures and the name of whoever stands behind them.
Name, address, services and opening hours, the same everywhere. If every site says something different, AI hesitates and names someone else.
AI recommends whoever it sees recommended. We aim to get you into the articles, lists and publications it uses as references in your sector.
We measure the visits that come from ChatGPT, Perplexity or Gemini and what those visitors do on your website, to find out whether the mentions bring customers.
Someone asking about a kitchen renovation company in Sherbrooke or a real estate agency in Sherbrooke does not get pages of results. They get a short reply with a few company names in it. The simulation here follows one company from absent to first recommendation.
Illustrative simulation. AI answers change every time a question is asked and nobody can guarantee a specific recommendation.
You tell us by video call what you sell and to whom, and we prepare the questions we are going to track.
We compare what AI says with your website and with the sources it cites. You get it in writing: what is missing and where to begin.
Content, structured data and media mentions, month by month, with tasks you know about in advance.
Every month we put the same questions to each engine and compare. What works gets more time and what does not gets changed.

Talk to the teamGEO stands for generative engine optimization. It is the work of getting assistants such as ChatGPT, Gemini and Perplexity, and the AI results in Google, to name and recommend your company when someone asks about what you sell. You will also see it called AI SEO or AI search optimization.
No. AI answers change from one run to the next and nobody outside controls them. What we do is raise the number of times you appear and prove it to you with the saved answers from each month, set next to the earlier ones.
Yes. Nothing in this work requires a visit. We run the questions as a customer in Sherbrooke would ask them, meet you by video call in English and send a monthly report. Between reports you can write to the team whenever you need to.
Usually not. We work on the website you have: we improve the copy, add frequently asked questions and structured data. If something bigger were needed, such as a redesign, we would explain why before doing anything. Web design is handled by the same team.
Yes. Visits that come from ChatGPT, Perplexity or Gemini can be separated out in your website analytics. We show them to you each month alongside the mentions, so you can see whether being named is turning into visits and inquiries.
It can be corrected, though not overnight. AI repeats what it finds, so the source of the error has to be fixed and the correct fact reinforced on your website and your profiles. With assistants that answer from training, the old version can linger until the model is updated.
The audit takes your sector, a list of questions a customer would ask and four AI engines. You get back a plain document showing where you appear today and what to do first. We usually reply within 24 hours.
