AEO and GEO explained: AI search for marketers

TL;DR:

• AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation) are strategies that enhance brand visibility in AI search results through different content formats.
• AEO aims for concise, structured answers for featured snippets, while GEO seeks authoritative citations within AI-generated summaries; both build on solid SEO fundamentals.
• They do not replace traditional SEO, which remains crucial, as early investment in technical SEO, entity building, and content structure ensures long-term AI search visibility.

AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation) are two distinct strategies that help brands gain visibility in AI-powered search results. AEO structures content to deliver concise, direct answers to platforms like Google’s featured snippets, Siri, and Alexa. GEO optimises content to be cited as a source within AI-generated, multi-source summaries produced by tools like ChatGPT, Perplexity, and Google AI Overviews. Understanding both is no longer optional for digital marketers and local business owners. AI search is reshaping how people find information, and the brands that adapt earliest will hold the strongest positions. MB Web’s AI Search service is built around exactly these principles.

What is the difference between AEO and GEO?

AEO targets concise answers for featured snippets, voice responses, and People Also Ask boxes, while GEO aims to get your content cited within longer, AI-generated summaries. The distinction matters because each approach targets a different type of AI output and requires a different content format. AEO success is measured by extraction rate, meaning how often your content is pulled as the direct answer. GEO success is measured by citation rate, meaning how often an AI model references your brand or content when synthesising a response.

SEO and GEO share 60% of their foundations, but the metrics diverge significantly. AEO rewards brevity and structure. A well-written FAQ answer of two to three sentences, marked up with schema, is a strong AEO asset. GEO rewards depth and authority. Content passages of 200 to 400 tokens are the units that large language models extract and synthesise, so your content needs to be both substantive and clearly attributed to a credible source.

Here is a quick comparison to make the distinction concrete:

The terminology around both disciplines is still evolving. Some marketers use AEO and GEO interchangeably, which creates confusion. The practical distinction is straightforward: AEO gets you the direct answer box; GEO gets you named as a source in the AI’s broader response.

Do AEO and GEO replace SEO?

They do not. Google states that optimising for AI features is fundamentally the same as optimising for search, and that misleading shortcuts do not produce results. AEO and GEO are specialised layers built on top of solid SEO foundations, not replacements for them. If your site has crawlability issues, thin content, or weak authority signals, no amount of AI-specific tactics will compensate.

The shared foundations across all three disciplines include:

• Crawlability and indexing: Search engines and AI models both need to access your content reliably. Broken pages and blocked resources hurt your chances across every channel.
• Schema markup: Structured data helps AI systems understand what your content is about and who produced it. Organisation schema, FAQ schema, and Article schema are all directly relevant.
• E-E-A-T signals: Google’s framework of Experience, Expertise, Authoritativeness, and Trustworthiness applies directly to AI citation decisions. AI models use cross-source agreement as a legitimacy signal.
• Entity structure: A consistent, verified presence across authoritative platforms strengthens the signal that your brand is a credible source.

Experts treat GEO as an extension of SEO with specialised tactics layered on top, not a separate discipline. The same logic applies to AEO. Chasing AI-specific shortcuts like unnecessary llms.txt files or excessive content chunking wastes time and budget. Google’s own guidance is clear: authoritative, well-structured, crawlable content is the foundation.

Pro Tip: Before adding any AEO or GEO tactics, audit your existing SEO health. Fix crawl errors, strengthen your schema markup, and build your E-E-A-T signals. These steps deliver returns across traditional search, voice, and generative AI simultaneously.

How is AI search changing digital marketing?

The shift from click-driven search to AI-answer-driven visibility is the most significant change in digital marketing since mobile search overtook desktop. Users increasingly receive complete answers without clicking through to a website. This changes the goal from ranking first to being cited or extracted as the authoritative source. For local businesses and B2B brands, the implications are direct and practical.

B2B brands should allocate 15 to 25% of their marketing budget to AI-native visibility combining SEO, AEO, and GEO. That figure reflects the growing proportion of research-stage and definitional queries being answered entirely within AI interfaces. A prospective client asking ChatGPT “what is the best web design agency in Sussex” will receive a synthesised answer, not a list of blue links. If your brand is not in the training data or cited sources, you are invisible to that query.

The query types that benefit most from AEO and GEO investment include:

• Definitional queries: “What is X?” questions are prime AEO territory. Clear, concise definitions with schema markup are extracted directly.
• Research-stage queries: “How does X work?” or “What are the benefits of X?” are GEO territory. AI models synthesise multiple sources to answer these, and being one of those sources builds brand authority.
• Comparison queries: “X vs Y” questions appear across both disciplines. Structured comparison content performs well in both featured snippets and AI summaries.
• Local intent queries: “Best X near me” queries are increasingly answered by AI with cited local sources. Consistent NAP (name, address, phone) data and local schema are critical here.

Early adopters investing in GEO gain first-mover advantages as category authority and AI citations compound over time. This is not a distant trend. Google AI Overviews, Perplexity, and ChatGPT are already the first stop for millions of searches every day. Our 2026 SEO trends article covers how these shifts are playing out specifically for businesses in the South East.

How to implement AEO and GEO effectively

Effective implementation follows a clear sequence. Start with technical SEO, then build your entity presence, then optimise content for AI extraction and citation.

1. Audit and fix technical SEO first. Use tools like Screaming Frog or Google Search Console to identify crawl errors, missing schema, and thin pages. Most effective AEO and GEO campaigns fix crawlability and schema before applying any AI-specific tactics.

2. Build your entity stack. An entity stack includes a verified Wikipedia or Wikidata presence, consistent Organisation schema with sameAs arrays linking to your social profiles, and authoritative mentions across trusted third-party domains. LLMs use cross-source agreement as a legitimacy signal, so the more consistently your brand appears across credible sources, the more likely you are to be cited.

3. Structure content for AI extraction. Write clear, direct answers to specific questions within your content. Each answer should be self-contained, two to four sentences, and immediately follow the question it addresses. This format serves both AEO snippet extraction and GEO passage retrieval.

4. Apply schema markup strategically. FAQ schema, HowTo schema, and Article schema all improve the likelihood of your content being extracted for AI responses. WordPress users can implement these through plugins like Yoast SEO or Rank Math. Custom-built sites benefit from manually coded JSON-LD.

5. Monitor AI citation performance. Tools like Semrush’s AI Overviews tracking, Ahrefs, and dedicated GEO monitoring platforms allow you to track when and where your content is cited. GEO citations typically emerge two to eight weeks after implementation, with full category-level authority taking six to twelve months to build.

Pro Tip: Do not choose between short answers and long-form content. Publish both. A concise FAQ section at the top of a page serves AEO. The detailed, authoritative body content below it serves GEO. One page can do both jobs.

AEO in trade: the Authorized Economic Operator explained

There is a second, entirely unrelated use of the acronym AEO that causes genuine confusion. In international trade, AEO stands for Authorized Economic Operator, a government certification that facilitates faster customs clearance and supply chain security. It is recognised by the UK, EU, US, China, and Japan, and is administered by national customs authorities.

The trade AEO certification is relevant to importers, exporters, and logistics businesses. Its benefits include:

• Faster border clearance and reduced physical inspections
• Priority treatment during customs controls
• Recognition across multiple trading nations through mutual recognition agreements
• Improved supply chain credibility with partners and clients

This has no connection to Answer Engine Optimisation. If you arrived at this article searching for the trade certification, the UK Government’s HMRC guidance is the correct resource. For everyone else, AEO in this article refers exclusively to Answer Engine Optimisation.

Key takeaways

AEO and GEO are complementary AI search strategies that require strong SEO foundations, distinct content formats, and separate success metrics to deliver results.
