Is GEO the same as AEO?

No, but they're close. AEO optimises for direct-answer placements like featured snippets and AI Overviews; GEO optimises for citations inside generative answers like ChatGPT and Perplexity. They share tactics — answer-first content, structure, authority — and reinforce each other.

Is SEO still relevant with AI search?

Yes. SEO fundamentals — quality content, authority, technical health — still matter and often feed the same signals AI engines use. AEO and GEO extend SEO for the AI era rather than replacing it.

Should I do SEO, AEO or GEO first?

Start with solid SEO foundations, then layer AEO to win specific questions and GEO to earn AI citations. In practice much of the work overlaps, so a good strategy advances all three together. An audit helps prioritise for your situation.

What's the difference between an answer engine and a generative engine?

An answer engine returns a single direct answer (a featured snippet, an AI Overview, a voice response). A generative engine composes an original, longer answer and may cite multiple sources (ChatGPT, Gemini, Perplexity). Google's AI Overviews sit at the overlap of both.

Do AEO and GEO require different content?

Largely the same content serves both: clear, answer-first, well-structured, authoritative pages with FAQ sections and schema. GEO adds extra emphasis on entity consistency and off-site citations, while AEO focuses on concise, extractable answers to specific questions.

Can one agency handle SEO, AEO and GEO?

Yes, and ideally one should, because the disciplines overlap so heavily that coordinating them is more efficient than splitting them. Alugence covers all three under one roof, which avoids duplicated work and conflicting priorities.

Which matters most for my business?

It depends on where your customers are. If they still search Google and click, SEO and AEO dominate; if they increasingly ask AI tools for recommendations, GEO grows in importance. Most businesses are seeing a shift toward AI answers, so a balanced strategy across all three is the safe bet.

Will AEO and GEO replace SEO jobs and budgets?

They're expanding the discipline, not replacing it. Much SEO work — content, technical health, authority — directly serves AEO and GEO. Teams and budgets are evolving to cover answer placements and AI citations alongside rankings, rather than abandoning search optimisation.

AEO vs GEO vs SEO: What's the Difference?

SEO optimises pages to rank as links; AEO (Answer Engine Optimisation) optimises content to be the direct answer in featured snippets and AI Overviews; GEO (Generative Engine Optimisation) optimises your brand to be cited inside generative AI answers like ChatGPT and Perplexity. They overlap heavily, and most brands need all three.

Search is fragmenting into three overlapping disciplines. The good news is that they build on each other, so understanding how they differ is the key to investing sensibly rather than chasing every acronym separately. This guide defines SEO, AEO and GEO, shows where they overlap, and explains how to combine them into a single modern search strategy.

SEO — ranking in search results

Search Engine Optimisation is the practice of improving a website so it ranks higher in traditional search results. It relies on relevant, quality content, sensible keyword targeting, backlinks from other sites, and technical health — speed, crawlability, mobile-friendliness and clean site structure.

SEO remains foundational for one simple reason: AI engines often draw on the same quality and authority signals that Google’s ranking systems use. A site with strong content and authority is easier for AI to find, trust and cite. So rather than being made obsolete by AI search, good SEO becomes the bedrock that AEO and GEO build on. What’s changing is that ranking a link is no longer the only goal.

AEO — becoming the direct answer

Answer Engine Optimisation structures content so an engine selects it as the answer — in a featured snippet, an AI Overview, or a voice response. It’s about answering a specific question cleanly and concisely, then making that answer extractable with FAQ formatting, schema and clear structure.

AEO’s defining move is answer-first writing: lead with a self-contained answer of roughly 40–60 words, then expand. Add FAQ sections, question-format headings, and lists or tables the engine can lift. The target is “position zero” — the answer shown above or instead of the ranked links. Read more in What is AEO?

GEO — being cited in generative answers

Generative Engine Optimisation makes your brand the source that generative AI quotes when it composes an answer. Where AEO targets a discrete answer slot, GEO targets being named and cited within a longer, synthesised response from ChatGPT, Gemini or Perplexity.

GEO leans hardest on three things: entity legibility (a consistent, machine-readable brand with schema and authoritative profiles), extractable content (clear, quotable, self-contained), and citations (mentions across trusted sources the models draw on). Read more in What is GEO?

How AEO, GEO and SEO overlap

Here’s the crucial point: these disciplines share most of their work. Answer-first, well-structured, authoritative content serves AEO and GEO at once, and rests on SEO fundamentals. Schema helps all three. Topical authority helps all three. Technical accessibility helps all three.

The differences are at the edges. SEO adds classic ranking factors like backlinks and technical SEO. AEO adds tight, snippet-eligible answers and FAQ schema. GEO adds entity consistency and off-site citation building. You’re not running three separate programmes so much as one strategy with three outputs — which is why treating them holistically is far more efficient than chasing each in isolation.

Which do you need?

For most brands, the answer is all three — but in sequence. SEO builds the foundation of quality, authority and crawlability. AEO wins the specific questions your audience asks. GEO turns that authority into citations across AI engines.

Where to start depends on your situation:

Weak technical or content foundations? Start with SEO fundamentals — everything else builds on them.
Strong content but losing visibility to AI answers? Prioritise AEO to win answer placements.
Want to be recommended when customers ask AI for options? Invest in GEO.

If you’re unsure, an AI search visibility audit shows where you stand across all three and which lever will move the needle fastest.

Building one search strategy across all three

The most effective approach treats SEO, AEO and GEO as a single, layered strategy:

Foundations (SEO): quality content, technical health, site structure, authority.
Answers (AEO): answer-first rewrites, FAQ blocks, schema, question research.
Citations (GEO): entity legibility, llms.txt and crawler access, off-site citation building.
Measurement: rankings and answer placements and AI citations, tracked together.

Because the work compounds, investing in the shared foundations first pays off across all three outputs. Alugence delivers exactly this joined-up approach through its AI search consultancy and AI SEO practice.
