SEO vs AEO vs GEO: three different endings to the same query
SEO competes for the click, AEO for the extracted answer, GEO to be a source the model reads. Here is what each one changes about the work, and what does not.
SEO, AEO and GEO are not three tactics competing for your budget. They are three different things that can happen after somebody types a question, and each one ends somewhere else.
SEO competes for the click. AEO competes for the answer box. GEO competes to be one of the sources a model reads before it writes an answer of its own.
SEO wins a ranked link the searcher clicks. AEO wins the extracted answer displayed above the links. GEO wins a citation inside an answer that a language model generated. About 80 percent of the work is the same for all three, because a page a model cannot crawl is a page it cannot quote.
What each one actually optimises for
The acronyms get defined constantly and it rarely helps, because the definitions do not say what changes about your Monday. So here it is as a job list.
| SEO | AEO | GEO | |
|---|---|---|---|
| Competes for | A ranked link | The extracted answer | A citation inside a generated answer |
| You win when | Someone clicks through | Your text is displayed as the answer | A model names you as a source |
| Graded on | Relevance, authority, links | Structure and extractability | Retrievability and corroboration |
| Main lever | Being the best page on the topic | Answering in one clean, liftable block | Being specific, quotable, and repeated elsewhere |
| Measured with | Position and clicks | Snippet ownership | Citation checks, branded query volume |
| Traffic effect | A visit | Often no visit | Sometimes a visit, always a mention |
The uncomfortable column is the middle one. Winning an answer box frequently means the searcher never arrives. That is not a reason to avoid it, but it does mean the metric you have been reporting for a decade stops describing the outcome.
The part that is identical, and it is most of it
Before the differences are worth any attention, the overlap:
- The page has to be crawlable. Server-rendered HTML, not behind a login, in the sitemap, not blocked in robots.txt.
- It has to be about one thing, clearly.
- It has to be genuinely better than what already ranks. No model cites a worse page than the one next to it.
- It has to load. Nothing here is a workaround for a slow site.
Get those wrong and none of the three works. Get them right and you are already most of the way to all three. Anyone selling GEO as a separate discipline with a separate budget is selling you the last 20 percent as if it were the whole thing.
What GEO genuinely adds
There are three things that are new, and they are new because a model retrieving and summarising is doing something different from a crawler ranking.
Extractability. A model lifting a sentence from your page gets no surrounding context. "It depends on the factors above" is worthless to it. "An AI sales agent automates three of the five stages of outbound" can be quoted standing alone. Write the answer as a complete, self-contained statement, near the top, before you build the argument for it.
Specificity. Vague claims get paraphrased without attribution. Specific ones get quoted with your name on them. A number, a named framework, a concrete threshold: these survive summarisation. "Best practices vary" does not.
Corroboration. This is the one people miss and it is the hardest. Models weight claims that appear in more than one place. A brilliant page nobody else references is a single unverified source. This is why publishing an original framework with a name is a GEO tactic and not just a branding one, and it is the same mechanism behind answering questions where they get asked: a named thing can be repeated by other people, and each repetition raises the odds that the model treats the claim as settled.
What AEO adds
Less, and it is more mechanical.
Answer engines extract. They want a question, immediately followed by an answer, in a structure they can parse without guessing. That means:
- Headings phrased as the question a person actually types.
- The answer in the first paragraph under the heading, not the fourth.
- Lists and tables for anything enumerable, because those are trivially liftable.
- FAQ structured data, used honestly. Mark up only questions the page genuinely answers. Promising an answer the page does not give is the kind of mismatch that gets rich results revoked across a whole domain rather than for one page.
Where to spend your time
If you are choosing, the order is not controversial:
First, the shared 80 percent. Crawlable, fast, one topic per page, better than what ranks. Everything else is built on this and none of it substitutes for it.
Then extractability. It is nearly free. Rewriting your opening paragraph to answer the question outright takes ten minutes per page and serves all three at once.
Then corroboration. Slow, and the only one that needs other people. Publish things worth referencing, name your frameworks, and be quotable enough that somebody quotes you.
Last, tooling. Revtive runs an SEO agent that researches measured keyword demand and tells you which articles are worth writing, which is the substrate work all three of these sit on top of. AI visibility trackers sample a set of prompts and report what they saw. That is genuinely useful for direction and it is not a ranking. Treat the numbers as a thermometer, not a scoreboard.
Measuring it, honestly
You cannot fully measure this yet and anyone who says otherwise is selling something.
Search Console does not separate traffic that came from an AI overview. It looks like ordinary Google search. Referrers from Perplexity and ChatGPT are visible in analytics, and they are a fraction of the real number, because plenty of people read an answer, remember a name, and search for it separately later.
The most honest proxy available: watch branded queries. If your name is appearing inside answers, people start searching for it directly. Branded query volume rising while impressions stay flat is the signature of being cited without being clicked. It is indirect and it is the best signal there is right now.
The take that is not exciting
GEO is not a replacement for SEO and it is not a new department. It is a set of writing and structural habits layered on the same foundation, plus one genuinely hard new requirement (corroboration) that looks a lot like the digital PR people have been doing for years.
The teams that do well at this over the next two years will mostly be teams that were already good at the boring part. The acronym is new. The work mostly is not.
