SEO, GEO and AEO: the difference, and why all three matter for an SMB

SEO: being found on Google

SEO (Search Engine Optimization) is everything that helps your site appear in Google's classic results when a customer types « plumber in Laval » or « accountant South Shore »: a fast, mobile-friendly site, clear pages about what you do and where, titles that match what people search, coherent internal links. It's the oldest and best-known lever — but no longer the only one.

GEO: being understood by AI

GEO (Generative Engine Optimization) targets engines that generate an answer instead of listing links: ChatGPT, Perplexity, Google's AI Overviews. They don't rank your page, they read it to compose an answer. For them to describe you correctly, your business must be stated unambiguously: who you are, what you offer, where you work. A vague page gets mis-cited — or not cited at all.

AEO: being chosen as the answer

AEO (Answer Engine Optimization) goes one step beyond GEO. GEO makes an engine understand you; AEO makes it pick you as the precise answer to a question — the box at the top of Google, « People Also Ask », a voice assistant's reply. The main lever: write the answer first, in one or two clear sentences, before the detail. That's exactly the format engines extract.

Why all three matter, not just one

Customers no longer search in a single way. The same shop owner might type a query into Google in the morning, ask ChatGPT « which web agency in Montreal » at noon, and ask their phone a question while driving. Betting on SEO alone means being present for some searches and absent from the rest. The three levers reinforce each other: content that is true, clear and useful ranks better, is better understood and gets kept as the answer — at the same time.

One trap to avoid: producing content only to please engines. Keyword-stuffed but empty text helps no one, and engines detect it better and better. The rule that works across all three levers is the same: tell the truth, be genuinely useful.

How Oeuvria handles all three together

What's the difference between SEO, GEO and AEO?

SEO gets you into Google's results; GEO makes AI (ChatGPT, Perplexity, AI Overviews) understand your business; AEO makes your content get picked as the direct answer to a question. Three complementary levers of one goal: being found.

Is SEO still enough in 2026?

No, not on its own. More and more customers get their answers through AI assistants and direct-answer boxes. Good SEO is still necessary, but GEO and AEO cover the searches SEO alone misses.

Do I have to pay for three separate services?

At Oeuvria, no: SEO, GEO and AEO come together as one service. Splitting them leaves blind spots.

Does it work for a small local business?

Yes. A merchant, tradesperson or professional in Montreal, Laval or the South Shore benefits from being visible across all three levers — that's often where local customers are.
