The shortest honest definition: SEO earns you a ranked position in a list of links. AEO — answer engine optimization — earns you a citation inside the answer itself. When a customer asks Google for “plumbers near me,” SEO decides whether you’re link number one or link number nine. When they ask ChatGPT “who’s the best plumber in town,” AEO decides whether the answer names you — because there is no list to rank in. That one difference drives everything else.
The comparison, without the jargon
| SEO | AEO | |
|---|---|---|
| Where you win | A results page of links | Inside the AI’s answer |
| What winning looks like | Ranking high enough to get the click | Being one of the two or three names the answer gives |
| What gets evaluated | Your pages | Your business as an entity — profile, reviews, mentions, and pages |
| Strongest signals | Links, keywords, technical health | Trusted sources: reviews, profiles, and content that answers real questions |
| Where the customer looks | Scans, compares, clicks | Reads the answer and often stops there |
| Failure mode | Page two of Google | Not existing in the conversation at all |
What actually changed
There’s no page two. A results page has ten spots and a long tail. An AI answer names two or three businesses, states them with confidence, and most people don’t ask a follow-up. The gap between “in the answer” and “not in the answer” is much starker than the gap between ranking third and ranking eighth ever was.
Engines read passages and entities, not just pages. A traditional search engine matched your page against a query. An answer engine assembles a judgment about your business — stitched together from your reviews, your Google profile, directories, local mentions, and what your own site says. You’re not optimizing a page anymore; you’re curating everything the engines can find about you.
Third-party sources got louder. In the link era, your own website was your main asset. Answer engines lean heavily on what others say — review platforms, community mentions, directories. A five-star review trail can outweigh your homepage.
The click became optional. Many questions now get answered without anyone visiting a website. If the engines can’t extract your information — your prices, your services, your answers — someone else’s gets used.
What didn’t change
More than the hype admits. Good content that genuinely answers questions wins in both eras. Technical basics still matter, because AI engines are built on crawlers — a site they can’t read can’t be cited. And trust was always the currency; reviews mattered before ChatGPT existed. AEO didn’t replace the fundamentals. It changed where the results show up and raised the price of being mediocre everywhere.
The practical upside of that overlap: AEO work usually improves your traditional rankings as a side effect. They’re cousins, not twins — but they share a bloodline.
What to actually do
Don’t buy a rebrand of your old SEO package with “AI” stapled to it. Start by finding out where you stand: check what ChatGPT says about your business — it takes five minutes. If you’re invisible, the three free fixes are the starting point. And if you want the full audit — every major engine, real buyer queries, screenshots, and the why behind the answers — that’s our free AI Visibility Report, delivered in 48 hours.
Is SEO dead?
No. Traditional search still drives real traffic, and the engines' AI answers are built on top of largely the same crawling and quality signals. SEO is the foundation; AEO is what you build on it. A business that abandons SEO for AEO is tearing out the ground floor.
Is AEO the same thing as GEO or LLMO?
Effectively yes. Answer engine optimization (AEO), generative engine optimization (GEO), and LLM optimization (LLMO) are competing names for the same practice: making your business the one AI-generated answers name and cite. The acronym war will settle eventually; the work is identical.
Can you do AEO without doing SEO first?
Partially, because some AEO work — reviews, business profiles, answer-shaped content — helps even on a technically mediocre site. But a site the crawlers struggle to read caps everything. In practice the work overlaps so much that doing AEO properly quietly fixes most of your SEO.
Should a small business invest in AEO now or wait?
The honest trade-off: AI visibility compounds slowly — name queries move in weeks, category queries take months. Waiting doesn't make it faster; it hands the head start to whichever competitor started first. Start small: check what the engines say about you today, fix the free things, then decide.
