SEO, AEO, and GEO: How Engine Optimization Works in 2026

"Getting found" used to mean one thing: ranking on Google. It now means three things, and most businesses are only paying attention to one of them. Search engines, answer engines, and generative AI each decide who gets seen in a different way — and increasingly, a real share of your customers never click a traditional blue link at all. Here's what each one actually is, and where to start.

1. SEO — still the foundation, not the whole picture

SEO gets your page ranked in traditional search results: technical crawlability, on-page structure, backlinks, and matching real search intent. This hasn't gone away and isn't going away — it's still the base layer everything else builds on. If Google can't crawl your site or your content doesn't match what people actually search for, nothing downstream works either.

What's changed is that ranking #1 no longer guarantees a click. Someone in Brussels searching "notary near me" might get their answer directly in a map pack, a featured snippet, or an AI summary — all without visiting a single website.

2. AEO — getting quoted, not just ranked

AEO (Answer Engine Optimization) is about structuring content so Google's featured snippets, "People Also Ask" boxes, and voice assistants can lift your answer directly — rather than just linking to your page further down the results. A featured snippet at position zero often gets more clicks than the "real" #1 result underneath it.

The format that wins here is simple: a clear question as a heading, followed immediately by a direct, complete answer in the first sentence or two. Long, meandering intros before you get to the point are exactly what AEO punishes — answer engines want the answer up front, not buried in paragraph three.

3. GEO — getting cited by AI, not just crawled by it

GEO (Generative Engine Optimization) is the newest of the three: making sure ChatGPT, Perplexity, and Google's AI Overviews cite your business when someone asks the AI a question instead of typing a search. Someone might ask "which notary in Brussels handles real estate closings" directly in a chat interface, and the AI's answer — with or without a link back to you — is what they act on.

GEO rewards largely the same things AEO does — clear structure, direct answers, credible signals — but with an added emphasis on being genuinely citable: specific facts, named expertise, and content that reads as a trustworthy source rather than a sales pitch dressed up as an article.

4. FAQ content is the single biggest lever across all three

A well-written FAQ section — a clear question, followed by a clear, complete answer — is disproportionately effective for SEO, AEO, and GEO at the same time. It's exactly the format featured snippets are built to extract, exactly what voice assistants read aloud, and exactly the kind of structured, single-purpose content generative AI tends to cite. Adding FAQPage structured data (the invisible schema markup behind the visible questions) makes that content even easier for all three systems to find and trust.

This is also one of the cheapest wins available: it doesn't require new traffic or new backlinks, just taking the questions your customers already ask you on the phone and turning them into clearly structured content on the page.

5. Local keywords matter more in the AI era, not less

It's tempting to think AI search flattens the advantage of local, specific content — it does the opposite. "Best notary in Brussels for successions" is a far better GEO and AEO target than "notary services," because it matches exactly how someone actually phrases a question to an AI assistant, and gives the AI a specific, confident fact to cite rather than a vague generality. In Belgium's multilingual market this compounds further: a French-speaking and Dutch-speaking visitor asking the same underlying question will phrase it differently enough that each language needs its own genuinely local, genuinely specific content — not a translated version of the other.

The takeaway

SEO, AEO, and GEO aren't three separate jobs — they're three engines rewarding largely the same underlying discipline: clear structure, direct answers, and genuine local specificity. Start with FAQ content and direct-answer formatting on the pages you already have; it's the fastest way to show up in all three at once.

Frequently asked questions

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

SEO gets your page ranked in traditional search results. AEO (Answer Engine Optimization) gets your content quoted directly in featured snippets, "People Also Ask" boxes, and voice search answers. GEO (Generative Engine Optimization) gets your business cited as a source when someone asks ChatGPT, Perplexity, or Google's AI Overviews a question instead of typing a search. All three reward the same underlying thing — clear, well-structured, genuinely useful content — but each optimizes for a different place someone might actually find you.

Do FAQ sections actually help with AI search?

Yes, and increasingly so. FAQ content answers one clear question with one clear answer, in a format that's easy for both featured snippets and AI models to lift and cite directly. Pages with genuine FAQPage structured data are disproportionately likely to be the source an AI Overview or chatbot points back to, simply because the question-answer format is exactly what these systems are built to extract.

Should Belgian businesses worry about GEO yet?

It's worth starting now rather than waiting. AI-generated answers are already showing up ahead of traditional results for many local searches, and being the source they cite requires the same fundamentals as ranking well normally — just applied with more attention to clear structure and direct answers. Businesses that already have solid SEO and FAQ content are closer to GEO-ready than they think; it's an extension of good practice, not a separate discipline to learn from scratch.
