Direct answer
Both still matter, but they do different jobs and the balance has shifted. SEO wins the click — it gets your page listed when someone searches. AEO makes you the answer the engine gives before any click happens. As more buyers act on the AI summary without scrolling, being the answer increasingly decides who gets considered. You don't abandon SEO; you stop assuming it's the whole job.
"SEO versus AEO" is framed as if you have to back one. You don't, and treating it as a choice is how businesses end up over-spending on the contest that no longer decides the outcome. They aren't rivals. They're two stages of the same buyer moment, and what's changed is which stage now does most of the deciding.
They're not rivals; they're two stages of the same moment
SEO competes to be the page a buyer clicks when they search. AEO competes to be the answer the engine assembles before the buyer decides whether to click at all. For years there was only the first contest, so being good at it was the whole game. Now there's a stage in front of it. Being absent from that stage means the buyer may never reach the results you worked so hard to rank in.
SEO tries to win the click. AEO tries to be the answer the click never has to happen for.
| SEO | AEO | |
|---|---|---|
| Competes to be | The page you click | The answer before the click |
| Rewards | A page that matches the query | An entity the engine can describe, trust and quote |
| Wins the moment | The buyer scrolls the results | The engine writes the summary above them |
| Fix when weak | Relevance, content, links | Identity, corroboration, quotable content |
What changed is where the decision gets made
A search result used to be a list of doors, and the buyer opened a few. Increasingly the engine reads the doors for them and hands back a summary with two or three names already in it. If you're in that summary, you're in the consideration set before anyone clicks anything. If you're not, your ranking is sitting underneath an answer that already pointed elsewhere. The contest didn't vanish — it moved upstream of the click, to whether the engine can describe and trust you well enough to name you.
Why being good at SEO doesn't carry over for free
You'd expect a company that ranks well to be cited well. Often it isn't, because the two reward different things. Ranking rewards a page that matches a query. Being the answer rewards an entity the engine can describe consistently, corroborate elsewhere and quote cleanly — the four things I set out as the Citable Entity Model in why you rank on Google but AI never cites you. The short version: SEO skill is necessary table stakes and no longer sufficient on its own.
So where should the next euro go?
Not all to one side. If buyers can't find you in ordinary search at all, fix that first — AEO won't rescue a company that's invisible to begin with. But if you already rank and the business still isn't following, more ranking is the wrong buy, and the gap is almost always on the answer side: identity, corroboration, quotable content.
Across the diagnostics I've run since AI Overviews launched: the point where engines start treating a site as a citable source tends to sit nearer a score of 60 than 90 out of 100, and most businesses measure in the high 30s the first time. That gap, not another ranking position, is usually what's costing the introduction. I've put market numbers on what closing it costs in what answer-engine optimisation actually costs.
How to tell which one is your problem
It's diagnosable, not a matter of taste. Search your core buyer queries and watch what happens. If you're nowhere in the ordinary results, that's an SEO problem and it comes first. If you rank fine but the AI answer above your result keeps naming competitors, more SEO won't touch it — that's an AEO problem, and it's deciding the shortlist before your ranking gets a vote. Most mid-sized firms I see have the second problem and keep spending on the first.
- Search your core buyer queries: are you absent from the results, or present but unnamed in the AI answer?
- If absent from results — that's SEO, and it comes first.
- If ranking but unnamed in the answer — that's AEO; more ranking won't touch it.
- Spend the next euro on the gap you actually have, not the one that's easier to buy.
If you can't tell whether your problem is ranking or being named in the AI answer, and you want to spend the next euro on the right one:
Spend another year optimising the click while the answer above it names someone else, and you'll fund a ranking your buyer never scrolls down to see.
