The work then covers AI crawler access (GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot), structured data, the llms.txt file, entities linked to Wikidata and the Knowledge Graph, and brand authority. The baseline takes eight weeks; the same queries are then rerun on a fixed schedule, with a monthly report. The agency also publishes its contextual density method and works in both French and English.

How to choose a GEO agency in Quebec

Before you sign, compare proposals on the same criteria.

AI crawler access to your site

OpenAI uses two separate crawlers: OAI-SearchBot powers ChatGPT search, while GPTBot is used to train its models, and each has its own setting. The agency should know which ones your robots.txt file blocks and why.

Solid SEO foundations for GEO

Google states that no special optimization is required to appear in AI Overviews or AI Mode. A serious GEO agency therefore starts with your site’s indexing, content and technical SEO.

Citation tracking on your queries

Ask how the agency measures your visibility in AI: the queries tracked, the engines tested (ChatGPT, Perplexity, Gemini, Google’s AI Overviews) and how often it runs the tests. Good tracking compares the same queries from month to month, shows the answers where your business is missing, then connects citations to AI-referred traffic and to the quote requests you receive.

A clear contract with no citation promises

No agency controls the answers AI models give. Ask instead about the monthly deliverables, the contract length, the notice period and who keeps the account access: transparency about your accounts matters as much as the report.

A GEO agency that knows Quebec

The same question can get a different answer in French and in English. Ask whether the agency tests your queries in both languages and in the cities you serve, from Montreal to Quebec City and the regions in between.

Where to start your GEO strategy

Start by checking what AI already says about your business: ask ChatGPT and Perplexity your customers’ questions, in French and English, then note who gets cited. Next, compare two or three agency proposals on the same deliverables. To see what our method has achieved, browse our case studies.

FAQ: GEO agencies in Quebec

What is a GEO agency?

A GEO agency optimizes a business’s presence in the answers of generative engines such as ChatGPT, Perplexity, Gemini and Google’s AI Overviews. GEO, short for Generative Engine Optimization, aims for a citation or recommendation in the answer rather than a position in a list of links. All five agencies on this list offer it alongside SEO.

What is the difference between GEO and SEO?

SEO improves how your pages rank in Google’s results. GEO works on how AI understands your business and cites it in its answers. Both rest on the same foundation: a site that crawlers can explore, clear pages about your services and consistent information across the web.

What is the difference between GEO and AEO?

AEO (Answer Engine Optimization) mainly targets direct answers from search engines, such as featured snippets and Google’s AI Overviews. GEO covers generative engines more broadly, the ones that write an answer from several sources, such as ChatGPT or Perplexity. Both rely on the same pages and are often worked on together.

How much does a GEO agency cost in Quebec?

Among the agencies on this list that publish their prices, a monthly engagement starts between $1,500 and $2,000 per month, then rises with the competition in your industry. A separately billed GEO audit costs $1,500 to $3,000 at My Little Big Web and $5,000 at Rablab. ProStar SEO provides its prices on request.

How long before you see GEO results?

The timeline depends on your site, your industry and your competitors. ProStar SEO mentions first citation movements after 60 to 90 days and estimates that a clear change in share of voice takes 6 to 12 months. Ask each agency what timeline it expects for your industry and what measurement it relies on.

Can an agency guarantee a citation in ChatGPT?

No. Nobody controls the answers AI models give, which change with the question, the language and model updates. An agency can commit to a method, deliverables and monthly tracking of your citations. Be wary of any proposal that promises a fixed spot in an AI answer.

Should you choose a GEO agency based in Quebec?

It isn’t required, but a local agency can test your queries in French and English, knows the cities you serve and writes in French suited to your customers. All five agencies on this list have an address in Quebec, shown in their profile.

What is share of voice in GEO?

Share of voice (also called citation share) is the proportion of tested queries where your brand appears in an AI’s answers. The agency asks ChatGPT, Perplexity or Gemini the same questions, then counts the answers that cite you alongside those that cite your competitors. ProStar SEO, SEO Montreal™ and My Little Big Web track it as a metric.
