Who's behind CannabisSEO.ai?
You're right to ask. An agency that wants to run your Google and AI visibility owes you transparency about who it is, where its expertise comes from, and how it works. Here's the honest answer.
Éric St-Cyr and a team trained on the web's hardest markets
My name is Éric St-Cyr, and I founded ProStar SEO. For more than a decade, our team has practiced search engine optimization for over a hundred clients across North America and Europe — and while I sign this page, every result we deliver is a team effort.
Our expertise was built where the competition is unforgiving: the most aggressive markets on the web. Cannabis and CBD. Online gambling. Cosmetic surgery. Dating. Industries where Google Ads is banned or severely restricted, where organic search is the only real acquisition channel, and where every lost position can mean tens of thousands of dollars in revenue.
In those markets, nobody survives on hunches or tactics copied from a blog. You survive by testing, measuring, and executing better than competitors spending seven-figure SEO budgets. That's the school that shaped our method — a multicultural team of SEO specialists, writers and developers working in English and French alike. CannabisSEO.ai focuses that hard-won expertise on one industry: cannabis SEO.
A scientific approach to SEO
We believe one simple thing: SEO is an engineering discipline, not fortune-telling.
Every recommendation we make rests on a test or a measured data point. We analyze the pages that actually dominate the search results for your keyword — their contextual density, their semantic entities, their content architecture, their link profile. Then we build pages calibrated to beat those benchmarks, and we measure the outcome. It's the same method behind every one of our cannabis SEO services, from technical SEO to content and link building.
When a hypothesis fails, we say so and adjust. When it works, we document it and replicate it. That test–measure–iterate loop is what separates scientific SEO from opinion SEO. Search engines evolve constantly — including answer engines like ChatGPT, Claude and Perplexity that are redefining online visibility right now. Only a method grounded in continuous experimentation keeps pace.
Why a cannabis-only agency — and why .ai
Cannabis is one of the toughest categories to market anywhere on the web. Paid ads are broadly banned, compliance is unforgiving, and the industry stigma makes authority genuinely hard to earn. That combination rewards specialists and punishes generalists — which is exactly why a dedicated cannabis SEO agency exists.
The .ai in our name is deliberate. As buyers increasingly ask AI assistants what to buy and who to trust, being the brand the model names is becoming the highest-value real estate in cannabis. We optimize for the answer engines, not just the search box — and almost no competitor in the space has started.
What you can expect from us
Honest expertise starts with clear commitments.
We never promise the number-one position. Anyone who guarantees it is lying, because no one controls Google's algorithm. What we promise is a method: benchmarked competitive analysis, documented deliverables, tracked indicators, and reports that show what's improving and what still needs work.
We work without long-term contracts. Our clients stay because the results convince them, not because a clause holds them. After more than ten years and a hundred-plus clients, that policy remains our best proof of confidence.
And we explain what we do. SEO should never be a black box. You'll understand every action taken on your site, and why it was taken.
