What is GEO and AEO? The Future of SEO in 2026

GEO (Generative Engine Optimisation) and AEO (Answer Engine Optimisation) are the disciplines for getting your brand cited in AI-generated search results — Google AI Overviews, ChatGPT, Perplexity, Claude. They represent the biggest shift in search since mobile-first indexing.

Why traditional SEO isn't enough

Around 60% of all Google searches now end without a click. On queries that trigger AI Overviews — roughly 25–35% of commercial-services queries in the UK — zero-click behaviour reaches 80%+. Ranking #1 organically still matters, but being the answer the AI quotes is increasingly more valuable.

What is GEO (Generative Engine Optimisation)?

GEO is the practice of optimising content to be cited by generative AI systems. This includes Google's AI Overviews (formerly SGE), ChatGPT's web browsing, Perplexity, and Claude. The key difference from traditional SEO: generative engines don't just rank pages — they synthesise answers from multiple sources and cite the ones they trust most.

What is AEO (Answer Engine Optimisation)?

AEO focuses specifically on being the direct answer to a question. This predates GEO — it started with Google's Featured Snippets and "People Also Ask" boxes. In 2026, AEO has expanded to cover voice assistants, AI chatbots, and any system that returns a direct answer rather than a list of links.

How to optimise for AI citations

1. Lead with the answer. First 50–80 words should directly answer the question in plain English. AI engines cite content that answers clearly.
2. Use structured markup. FAQPage, HowTo, Article schema. AI engines parse structured data more reliably than unstructured HTML.
3. Cite primary sources. AI engines preferentially cite content that itself cites authoritative sources — .gov.uk, ONS, ICO, IAB UK.
4. Update regularly. Date-stamped content with recent statistics is cited 2–3x more often than undated evergreen content.
5. Build topical authority. A single article won't earn citations. A hub page plus 15–25 supporting pieces builds the authority signal AI engines look for.

What this means for London businesses

If your competitors are being cited in AI Overviews and you're not, they're capturing demand you can't even see in your analytics. Every SEO retainer at Meridian includes structured GEO/AEO work — we've got clients cited in Google AI Overviews and ChatGPT within 4 months of starting.

GEO/AEO checklist

• Audit which of your target queries trigger AI Overviews (use Ahrefs or SEMrush SERP features filter)
• Check if your brand is being cited (search your queries in ChatGPT and Perplexity)
• Restructure top 10 pages to lead with the answer, not the preamble
• Add FAQPage schema to every service and borough page
• Build topical clusters (hub + supporting pages) for each service vertical
• Date-stamp all content and commit to quarterly updates
