GEO vs SEO vs AEO: What Each One Actually Does, and Which You Need First

Three acronyms. Roughly forty agencies in your inbox claiming to have mastered all of them. And a fair amount of what is being sold as GEO right now is SEO with a new invoice header.

So let's be straight about what is actually new, what is repackaged, and what you should do first.

The short version

SEO gets your pages found and ranked.

AEO gets your content structured so it directly answers the question someone asked.

GEO gets your brand understood well enough that an AI system mentions you when nobody typed your name.

They share most of their DNA. Where they diverge matters, and it is not where most agencies say it is.

SEO: still the thing that pays the bills

Technical health, crawlability, site architecture, content, internal links, authority. Nothing here has changed, and anyone telling you SEO is dead is selling you the replacement.

What has changed is that SEO is no longer the whole job. It is the entry fee.

If Google cannot crawl you, no AI system will cite you either. Most of them are reading the same web. A site with broken indexation, thin content and no authority does not have a GEO problem. It has an SEO problem wearing a more fashionable name.

AEO: writing for the question, not the keyword

AEO is the most straightforward of the three and the one most agencies underrate, because it is unglamorous.

Traditional SEO starts with a keyword: digital marketing agency.

AEO starts with what someone actually typed or said: how much does a digital marketing agency cost, and what am I paying for?

The difference in the output is structural. An AEO page answers in the first two sentences, then earns the rest of the read by adding context. It does not spend four hundred words warming up. It does not bury the number.

This matters because answer-style results, whether in AI Overviews or an assistant, tend to pull from content that already reads like an answer. If your page takes six paragraphs to make a claim, there is nothing clean to lift.

Practical version: for every commercial page you own, write down the ten questions a buyer asks before they contact you. Answer each one in under sixty words somewhere on your site. That is most of AEO.

GEO: the part that is genuinely different

Here is the real shift, and it is not a tactic.

Traditional search is page-level. You optimize a page, that page ranks, that page gets the click.

Generative search is entity-level. Somebody asks which fintech marketing agencies are worth talking to. No specific page ranks. Instead, a system assembles an answer from everything it understands about the category and the brands in it. Your website is one input. So is the industry publication that quoted your founder, the review platform, the partner site, the case study someone else wrote about working with you, the podcast transcript.

You cannot optimize your way into that with a landing page. You have to actually exist in the category.

Which means GEO work looks less like SEO and more like a mix of PR, original research, and obsessive consistency:

Be consistent about who you are: Same company description, same service names, same leadership, same locations, everywhere. Contradictory information is worse than thin information, because it makes you harder to model.

Publish things worth citing: Original data, real case studies with numbers, an actual point of view. Content that restates the consensus gives nothing anyone would reference.

Be visible off your own domain: Third-party mentions carry weight precisely because you did not write them.

Cover a topic properly: Twelve connected pieces on one subject build a recognizable expertise. Twelve disconnected posts on twelve subjects build nothing.

Be crawlable by the AI crawlers specifically: This is the boring technical one people miss. If you have blocked the crawlers, none of the above matters.

Nobody can guarantee you a citation

Worth saying plainly, because someone will pitch you otherwise.

There is no mechanism to buy, guarantee, or reliably force placement in an AI-generated answer. OpenAI has said as much about ChatGPT Search directly. Anyone offering guaranteed AI citations is either misunderstanding the system or hoping you do.

What you can control is whether you are the kind of brand these systems have enough evidence to mention confidently. That is it. That is the entire game.

So which one first?

For most businesses: fix SEO, build AEO into how you write, run GEO continuously.

The reason is unglamorous. GEO depends on things SEO produces. Authority, crawlability, a body of content, third-party references. Skipping to GEO with a broken foundation is buying a roof before the walls.

But that sequence is a default, not a law. Three situations flip it:

• Your fundamentals are fine and your AI visibility is zero: You rank, you get traffic, and you appear in exactly none of the AI answers your competitors show up in. Accelerate GEO now, because that gap widens.
• Your traffic is decent and your content answers nothing: Lots of pages, no direct answers, high bounce on informational queries. AEO is the cheapest fix on this list and usually the fastest to show movement.
• You are new, or your site is a mess: SEO. All of it. Nothing else will compound until that is true.

The question almost nobody can answer

Ask an agency pitching you GEO how they will measure it.

Most will change the subject to rankings, or show you a traffic chart, or talk about "share of voice" without defining it. If they cannot tell you which prompts they will track, how often, across which systems, and what the baseline is today, they are not doing GEO. They are doing SEO and hoping.

Real measurement means a defined set of buyer prompts, checked on a schedule, across the assistants your customers actually use, with a record of which brands got named and whether you were one of them. It is tedious. It is also the only way anyone knows if this is working.

We track it because we have to prove it. Three of our client brands are currently cited in Google AI Overviews, and we can show you the prompts.

Conclusion

It is not SEO versus GEO. That framing exists to sell a new retainer.

It is one visibility system with three jobs: be findable, be answerable, be citable. Most of the work overlaps. The parts that do not overlap are the parts that need doing deliberately, and almost nobody is doing them because they are slower and harder than publishing another listicle.
