SEO vs AEO vs GEO: What Should Your Business Invest in First?

Two years ago, most business owners only had to think about one acronym. Now there are three. Agencies are pitching SEO services, AEO packages and GEO strategies, often in the same proposal, and it's hard to tell which ones are genuinely different and which are old ideas with new labels.

The confusion is understandable. The terms overlap, the industry hasn't fully agreed on definitions, and some of the loudest voices are the ones with something to sell.

So let's keep this practical. Below, we explain what each one actually means, where they differ, where they're really the same work, and the order in which most businesses should invest in them. If you only have budget for one thing this year, you'll know what it should be by the end.

 

Why Everyone Is Suddenly Talking About AEO and GEO

For most of the last twenty years, getting found online meant one thing: ranking on Google. Then the way people search started to split.

Some people now get their answer directly on the results page, from a featured snippet, a "People also ask" box or an AI Overview, without clicking anything. Others skip Google entirely and ask ChatGPT, Perplexity or Gemini to explain something or recommend a provider.

Each of those places works a little differently, and that's where the new terms come from. AEO is about being the answer. GEO is about being the brand AI tools mention. SEO is still about being found in search. All three matter, but not equally, and not all at once.

What SEO Means Today

SEO, or search engine optimisation, is the work of getting your website to rank in search results and turning those visits into enquiries or sales.

It covers three broad areas. Technical SEO makes sure search engines can crawl, understand and trust your site. On page SEO makes sure your pages clearly match what people are searching for. Off page SEO builds your authority through links, mentions and reviews from other websites.

Good SEO services today go beyond chasing rankings. They focus on the pages that bring in business, such as service pages, product categories and location pages, and they're judged on leads and revenue rather than traffic alone.

What AEO Means

AEO, or answer engine optimisation, is about getting your content selected as the direct answer to a question.

Think about someone searching "how long does a kitchen renovation take." Google might show a short answer at the top of the page, pulled from one website. It might also answer a string of related questions in a "People also ask" box, or read an answer aloud through a voice assistant. AEO is the work of making your content the source for those answers.

In practice, AEO means finding the real questions your customers ask, answering them clearly and early on the page, structuring content with sensible headings, and adding structured data so search engines understand exactly what each section covers.

The idea isn't entirely new. Good SEO specialists have been optimising for featured snippets for years. What's changed is how many places now pull short, direct answers, and how much visibility depends on being the one that gets picked.

What GEO Means

GEO, or generative engine optimisation, focuses on how your brand appears in answers written by AI tools such as ChatGPT, Gemini, Perplexity, Claude and Google's AI Overviews. The term itself comes from academic research published in 2023 that studied how content gets cited in AI generated answers.

Here's the key difference from AEO. Ask ChatGPT "which CRM is best for a 20 person sales team" and it won't quote one website. It will pull together information from many sources and recommend a few brands. Your goal isn't to own the answer. It's to be one of the names in it, described accurately and favourably.

That depends heavily on what the rest of the internet says about you. GEO work includes getting your brand mentioned on credible third party sites, building reviews, keeping your business details consistent everywhere, publishing original data or opinions others will reference, and making your own content clear enough that AI tools describe you correctly.

How SEO, AEO and GEO Differ

	SEO	AEO	GEO
Main goal	Rank and earn clicks	Be the direct answer	Be mentioned and recommended by AI
Where you appear	Search results pages	Snippets, answer boxes, voice results, AI Overviews	ChatGPT, Gemini, Perplexity, AI Overviews
What success looks like	Traffic, enquiries, sales	Your content shown as the answer	Your brand named in AI responses
Main levers	Technical health, content, links	Question focused content, clear structure, schema	Brand mentions, reviews, reputation, entity clarity
Depends mostly on	Your own website	Your own content	What the wider web says about you
Maturity	Well established	Established, growing	New and still evolving

The last two rows are worth pausing on. SEO and AEO are mostly about your own website. GEO depends much more on your reputation across other websites, which is why it takes longer and why it's harder to control.

Where They Overlap

Here's something agencies selling three separate packages don't always mention: a lot of the work is shared.

A fast, well structured website helps all three. A clear, expert answer to a real customer question can rank on Google, get picked as a featured snippet and be cited by an AI tool, all from the same paragraph. Strong reviews and credible mentions build authority for SEO and reputation for GEO at the same time.

That's why we think of them less as three separate services and more as three layers of the same foundation. SEO is the base. AEO sharpens how your content answers questions. GEO extends your visibility beyond your own site.

If someone quotes you three completely separate price tags with no shared work between them, ask what exactly is different.

What to Invest in First

For almost every business, the right order is the same.

First, SEO. Get your technical foundation right and make sure your key pages rank for the searches that bring in business. Without this, AEO and GEO have very little to build on. AI tools and answer boxes draw heavily from content that search engines already trust.

Second, AEO. Once your core pages are in good shape, rework them and your supporting content to answer customer questions clearly and directly. Add FAQ sections where they genuinely help, tighten your headings and add structured data. This is usually quick to implement and builds directly on your SEO work.

Third, GEO. With a strong site and clear answers in place, start building your presence across the wider web. Earn mentions in industry publications, grow reviews, keep your business information consistent and track how AI tools describe you. This is slower work, but it compounds over time.

The one exception is a business that already ranks well and has strong content. In that case, moving quickly into GEO makes a lot of sense, because the foundation is already done.

How Priorities Change by Business Type

The order stays the same, but the balance shifts depending on how you sell.

Local service businesses like clinics, law firms and home services should focus heavily on SEO and local search, especially Google Business Profile and reviews. Reviews also feed directly into how AI tools recommend local providers.

B2B companies have the most to gain from GEO. Buyers increasingly ask AI tools for vendor shortlists, and those tools lean on industry publications, comparison sites and review platforms. Being present in those places matters a lot.

Ecommerce brands should prioritise SEO for category and product pages, where most revenue comes from. AEO helps with buying guides and product questions, while GEO matters for "best product for" type searches.

Education providers benefit strongly from AEO, since students and parents ask a huge number of questions about courses, fees, eligibility and outcomes before applying.

New brands with little online presence should focus on SEO and on building genuine mentions early. AI tools rarely recommend brands the rest of the web hasn't talked about.

How to Measure Each One

Each layer needs its own scorecard.

SEO is measured through rankings for commercial keywords, organic traffic to key pages and, most importantly, enquiries and sales from organic search.

AEO is measured by tracking how often your content appears in featured snippets, "People also ask" boxes and AI Overviews for your target questions. Google Search Console also shows how your question focused pages are performing.

GEO is harder to measure because AI answers vary from person to person and day to day. The most practical approach is to run a consistent set of questions through ChatGPT, Gemini, Perplexity and Google every month, and record whether your brand appears, how it's described and who appears instead. Over time, the trend tells you whether your work is paying off.

Mistakes We See Businesses Make

Buying GEO before fixing the basics. No amount of AI optimisation will help a slow, thin website that doesn't rank for anything.

Turning every page into an FAQ. Question and answer sections help when they answer real questions. Stuffing them onto every page just makes content harder to read.

Chasing quick technical fixes. Adding a new file or a bit of markup and expecting AI tools to start recommending you won't work on its own. AI visibility comes mainly from reputation and useful content.

Believing guarantees. Nobody can guarantee your brand will appear in ChatGPT. Any agency that promises it is overselling.

Measuring everything with traffic. As more answers appear directly in search and AI tools, traffic alone undercounts your real visibility. Track enquiries and brand mentions too.

Frequently Asked Questions

What is the difference between SEO, AEO and GEO?

SEO helps your website rank in search results and earn clicks. AEO helps your content get chosen as the direct answer in snippets, answer boxes and voice results. GEO helps your brand get mentioned and recommended in AI generated answers from tools like ChatGPT, Gemini and Perplexity.

Do I need SEO services if I invest in AEO and GEO?

Yes. AEO and GEO both depend on the foundation that SEO builds. Answer boxes and AI tools draw mainly from content that search engines already trust. Without solid SEO, your AEO and GEO efforts have far less to work with.

Which is more important for small businesses, SEO or GEO?

For most small businesses, SEO comes first, especially local SEO and reviews. Those efforts also support GEO, since AI tools often recommend local businesses with strong reviews and consistent information. Dedicated GEO work makes more sense once your core rankings are in place.

How long does GEO take to show results?

GEO usually takes longer than SEO because it depends on building mentions and reputation across other websites. Most businesses start seeing changes in how AI tools describe them within four to nine months of consistent work, depending on their industry and starting point.

Can one agency handle SEO, AEO and GEO together?

Yes, and it's usually better that way. Because so much of the work overlaps, one team handling all three avoids duplicated effort and keeps your content, technical setup and reputation building aligned. Just make sure the agency explains clearly what each part of the work involves.

The Bottom Line

SEO, AEO and GEO aren't competing options. They're three layers of the same goal: making sure your business is found, understood and trusted wherever people look for answers. Start with SEO, because everything else depends on it. Add AEO to make your content the clearest answer available. Then build GEO to make your brand the one AI tools recommend.
