You have a finite budget and three acronyms competing for it. AEO, GEO and SEO all promise to get you found, and every vendor swears theirs is the one that matters now. The honest answer is that most UK businesses need all three, but not in equal measure and not in the same order. This guide compares AEO vs GEO vs SEO on what each actually does, where they overlap, and how to split your spend by business type. No jargon, no hype. Just a decision framework you can act on this quarter.
Key Takeaways
- SEO ranks your pages in traditional search. It is still the foundation, and AI engines disproportionately cite pages that already rank well.
- AEO structures content to be lifted as a direct answer in featured snippets, voice results and People Also Ask boxes.
- GEO gets your brand cited and recommended inside AI answers from ChatGPT, Perplexity, Claude and Google AI Overviews.
- The three overlap heavily. One well-built page can rank, win a snippet and get cited by AI at the same time.
- A sensible starting split for most UK SMEs is roughly 70/20/10 across SEO, GEO and AEO, then flip it as your sector shifts.
- Prioritise by business type: local service, B2B and ecommerce each need a different weighting.
What is the difference between SEO, AEO and GEO?
SEO optimises your site to rank in Google’s results so a person clicks through. AEO structures content to be pulled straight into a featured snippet, voice answer or People Also Ask box, often with no click. GEO gets your brand named and recommended inside AI-generated answers from tools like ChatGPT and Google’s AI Overviews. In short: SEO wins the ranking, AEO wins the answer box, GEO wins the recommendation.
The differences are real, but smaller than the marketing suggests. Industry analysts note that GEO and answer-led tactics overlap heavily with SEO fundamentals, and there is still no agreed taxonomy across the field.
That matters commercially. It means you are not buying three separate programmes. You are building one strong asset with three payoffs, which protects your budget.
How do SEO, AEO and GEO compare?
The quickest way to see the difference is side by side. Each channel has a different goal, timescale and way of measuring success, which is exactly why you cannot judge them all on rankings alone.
| Factor | SEO | AEO | GEO |
|---|---|---|---|
| Goal | Rank a page so a human clicks | Win the answer box or voice result | Get cited and recommended in AI answers |
| Where it shows | Google and Bing results pages | Featured snippets, People Also Ask, voice | ChatGPT, Perplexity, Claude, AI Overviews |
| Timescale | 3 to 9 months | 1 to 4 months on existing ranking pages | Ongoing, less predictable |
| Effort | High: technical, content, links | Medium: restructure and schema | Medium to high: content depth plus off-site presence |
| Measurement | Rankings, organic traffic, conversions | Snippet captures, voice visibility | AI citations and brand mentions in answers |
| Foundation needed | The base layer | Built on SEO | Built on SEO |
The pattern is clear. SEO is the foundation. AEO and GEO are extensions that inherit most of your SEO work rather than replacing it.
Do I need all three, or can I pick one?
Most UK businesses need all three, but you sequence them rather than launch them together. SEO comes first because it is the technical and authority base that makes your pages discoverable. AEO and GEO then build on that base, reusing the same content and schema. Picking only one leaves gaps: SEO alone misses the zero-click and AI traffic, while GEO alone has no ranked pages for AI engines to cite in the first place.
Here is the practical logic. AI engines tend to cite sources that already rank well and carry clear authority signals. So strong SEO quietly powers your GEO results. Skip the foundation and the clever AI work has nothing to stand on.
“In my years running marketing in the property and facilities management sectors, the businesses that won were rarely the ones chasing the newest tactic. They were the ones with solid fundamentals that everything else could build on. AEO and GEO are no different.” – Marcus, Lobo Digital
How should I split my budget across SEO, AEO and GEO in 2026?
For most UK SMEs, a sensible starting point is roughly 70% SEO, 20% GEO and 10% AEO. That weighting funds the foundation first, invests in AI visibility as a growing channel, and spends a little on answer-box formatting that is cheap to add once your content already ranks. It is a starting split, not a rule. You flip it as your sector and buyer behaviour change.
When should you flip it? A few triggers:
- Your rankings are healthy but AI Overviews and zero-click answers are eating your traffic. Shift spend toward GEO and AEO to reclaim visibility in those surfaces.
- Your buyers research in AI tools before they ever visit your site. This is common in B2B. Lean harder into GEO, because being the recommended option is now a top-of-funnel channel.
- You are starting from a weak or new website. Push even more into SEO first. There is no shortcut around the foundation.
To understand why GEO increasingly earns its own line in the budget, our guide to generative engine optimisation breaks down how AI citations actually work.
Which should a local service business prioritise?
Local service businesses should prioritise SEO first, then AEO, with lighter GEO. Local buyers still search Google for nearby providers and read reviews before they call, so ranking in the map pack and local results drives the most leads. AEO matters because voice and conversational queries (“who can unblock a drain near me today”) increasingly return direct answers. GEO is worth a small ongoing investment as AI tools start recommending local firms.
Imagine a 12-person cleaning firm in Croydon. The bulk of its budget should go to local SEO and reviews, a slice to answer-first FAQ content, and a smaller slice to keeping its brand consistent across the sites AI engines tend to cite.
Which should a B2B business prioritise?
B2B businesses should weight more toward GEO than most, because buyers now ask ChatGPT, Claude and Perplexity for vendor shortlists before they visit any website. If your brand is not cited in those answers, you are invisible at the exact moment a decision is forming. SEO still matters for the research and comparison content buyers read once they click through, but GEO has become a genuine top-of-funnel channel in B2B.
A realistic B2B split might be closer to 50% SEO, 35% GEO and 15% AEO. The prize is being the named, recommended option when a prospect asks an AI assistant who to shortlist.
Which should an ecommerce business prioritise?
Ecommerce businesses should keep SEO central for product and category rankings, then invest in AEO for structured product answers and GEO for appearing in AI shopping and comparison responses. Product discovery increasingly happens through AI-synthesised answers and voice, so structured data and clear, extractable content directly affect whether your products surface. SEO still drives the majority of qualified traffic and revenue.
Practically: keep your technical SEO and product schema tight, format specs and FAQs so they are easy to extract, and make sure your brand and product information is consistent across the third-party sites AI engines reference.
For a foundation-first approach across all three, our SEO services page sets out how we sequence the work.
Does AEO still matter now that AI Overviews exist?
Yes. AEO and AI Overviews are not the same thing. AEO covers featured snippets, People Also Ask and voice answers, which still appear across billions of searches and still drive visibility and clicks. AI Overviews are one more surface that rewards the same answer-first structure. Formatting a page so a machine can lift a clean answer helps you win in both places at once, which is why AEO is cheap to add and worth keeping.
FAQs
Do I need all three: SEO, AEO and GEO?
Most UK businesses do, but not at once. SEO is the foundation that makes your pages discoverable and trusted. AEO and GEO build on it, reusing the same content and schema for extra visibility in answer boxes and AI answers. The smart move is to sequence them: get the foundation right, then extend. Running three separate programmes wastes budget, because the work overlaps by design.
Which is cheapest to start with?
AEO is usually the cheapest to add, because it mostly restructures content you already have. Clear question-and-answer formatting, clean headings and FAQ schema on pages that already rank can win snippets quickly, often within one to four months. SEO is the bigger long-term investment, and GEO sits in the middle. If budget is tight, tighten AEO on your best existing pages first.
Does AEO still matter now AI Overviews exist?
Yes. AI Overviews are an additional surface, not a replacement for featured snippets, People Also Ask and voice results, which still appear across a large share of searches. The same answer-first structure wins in both. Because AEO formatting is inexpensive to add once content ranks, it remains one of the best-value parts of the mix in 2026.
How is GEO different from SEO?
SEO gets a page to rank so a person clicks through to your site. GEO gets your brand cited or recommended inside an AI-generated answer, often without a click. The tactics overlap heavily, since AI engines tend to cite pages that already rank well. Think of GEO as extending strong SEO into AI answers, not as a separate discipline that replaces it.
How do I measure GEO if there are no rankings?
You measure GEO by tracking brand mentions and citations inside AI answers, not by traditional rankings. That means checking whether tools like ChatGPT, Perplexity and Google’s AI Overviews name or recommend you for your key topics, and how accurately they describe your brand. Visibility is less stable than organic rankings, so treat it as a trend to monitor over time rather than a single fixed position.
What if I only have budget for one channel?
Start with SEO. It is the foundation the other two build on, and AI engines disproportionately cite pages that already rank and carry authority. Investing in SEO first quietly improves your AEO and GEO results later, because you are creating ranked, trusted content for answer boxes and AI tools to draw from. One well-structured, well-sourced page does most of the job across all three.
