SEO, AEO, GEO: Three Ways People Now Find You

For twenty years, being findable online meant one thing: rank on Google's first page. Someone typed a query, saw ten links, and clicked one. Your job was to be among those ten.

That model is quietly breaking. A large and growing share of searches now end without a click — the answer appeared directly on the results page, or a voice assistant read it aloud, or someone asked ChatGPT instead of searching at all.

Three acronyms have appeared to describe this. They sound like marketing invention, and partly they are. But underneath, they describe three genuinely different ways people encounter your business.

The Three, Briefly

SEO — Search Engine Optimisation. Getting your pages to rank in traditional search results. The classic discipline: keywords, links, technical health, content quality.

AEO — Answer Engine Optimisation. Getting your content used as the answer — featured snippets, "People Also Ask" boxes, voice assistant responses. The user often never visits your site; they get the answer directly.

GEO — Generative Engine Optimisation. Getting mentioned and cited when someone asks an AI assistant — ChatGPT, Claude, Gemini, Perplexity, or Google's AI Overviews. The AI summarises multiple sources and names some of them.

Note on the acronym: GEO in this article means Generative Engine Optimisation. It's unrelated to local/geographic SEO, which shares the abbreviation and causes constant confusion.

How They Differ in Practice

Take one question: "What's the best CRM for a small team?"

SEO answer: Your comparison article ranks fourth. The user scans the page, clicks your link, reads, maybe converts. You get a visit and a chance to persuade.

AEO answer: Google pulls three sentences from your article into a box at the top of the page, with your name attached. Most users read the box and stop. You get visibility and authority, but far less traffic.

GEO answer: Someone asks an AI assistant. It replies with a paragraph recommending three tools and cites its sources. If you're one of the three, you've been recommended by something the user treats as a neutral advisor — arguably stronger than a ranking, but you have less control over how you're described.

Notice what changes across the three: traffic falls, but influence at the decision moment rises. That trade-off is the real story.

What Each One Actually Requires

SEO: still the foundation

Nothing here is new, and none of it has stopped mattering. AEO and GEO both draw from search indexes — if you can't be found conventionally, you won't be quoted or cited either.

The essentials:

Technical health — fast pages, crawlable, mobile-friendly, clean site structure
Content that matches intent — answer the question the searcher actually has, not the one your keyword tool suggested
Authority — links and mentions from sources people already trust
Freshness — updated content beats abandoned content on the same topic

Treat this as table stakes. Everything else builds on it.

AEO: structure your answers so they can be lifted

Answer engines need to extract a clean, self-contained response. Content that rambles toward its point is hard to extract; content that states the answer plainly is easy.

What works:

Answer first, then elaborate. Put a direct 40–60 word answer immediately under the heading. Context and nuance follow.
Use questions as headings. "How much does a website cost in Sri Lanka?" is a heading an answer engine can match to a query. "Pricing" is not.
Add schema markup. FAQPage, HowTo, Product, and Organization structured data tells search engines exactly what each part of your page is. This is one of the highest-return technical changes available.
Format for extraction. Short paragraphs, real lists, comparison tables. Walls of text rarely get pulled into an answer box.
Write the way people speak. Voice queries are longer and more conversational than typed ones — "what does it cost to build a website" rather than "website cost".

GEO: be the source AI models reach for

Generative models don't rank pages. They synthesise from sources and cite what they consider credible. Getting into that set works differently.

What appears to matter most:

Be mentioned in places AI systems already trust. Industry publications, comparison sites, forums, and directories are all training and retrieval material. A single mention in a well-regarded roundup can be worth more than a dozen pages on your own site.
Publish real, specific information. Original data, concrete numbers, named case studies, clear methodology. Generic content gets summarised away; specific content gets cited because it's the only place the detail exists.
State facts plainly and keep them consistent. If your pricing, location, and services are described identically across your site, your profiles, and third-party listings, models have a consistent picture to work from. Contradictions get resolved by ignoring you.
Make claims attributable. "Sites we've migrated to static hosting typically load in under a second" is quotable. "We deliver best-in-class performance" is not.
Keep content accessible to crawlers. Content that only appears after JavaScript execution, or sits behind a login, is much less likely to be retrieved.

There's an uncomfortable honesty required here: GEO is young, the mechanisms are partly opaque, and anyone selling certainty about it is guessing. What's clear is that the inputs — credible mentions, specific facts, consistent information — are things worth having anyway.

The Practical Overlap

Here's the reassuring part. Do the following and you're serving all three at once:

Answer a real question directly, near the top of the page.
Structure the page with question-shaped headings and clean markup.
Include something specific that only you can provide — your data, your results, your process.
Keep your facts consistent everywhere your business appears.
Earn mentions from sources that already have credibility.

That's not three strategies. It's good content and clean technical execution, which happens to be what all three systems reward.

What This Means for Measurement

The uncomfortable operational consequence: your traffic can fall while your influence grows. Impressions rise, clicks don't. Someone arrives ready to buy, having never visited a page you can attribute.

Worth tracking alongside the usual numbers:

Impressions vs. clicks in Search Console — a widening gap often means you're being used as an answer, not a destination
Branded search volume — people looking for you by name is a strong signal that something upstream is working
Direct and "unattributed" conversions — often AI-influenced discovery arriving with no referrer
Actual AI answers — periodically ask the major assistants the questions your customers ask, and see who gets named

That last one is unglamorous and manual, and it's currently the most reliable check available.

The Underlying Shift

The old game was ranking a page. The new game is being the source that answers get built from — whether that answer appears in a snippet, a voice reply, or an AI summary.

The tactics differ. The requirement doesn't: publish genuinely useful, specific, well-structured information, and make it easy for machines to understand. That was good advice in 2015. It's just become considerably harder to fake.
