SEO vs AEO vs GEO: The 2026 Search Visibility Stack Explained

Search isn't one channel anymore. The same buyer now bounces between Google's classic blue links, Google's AI Overviews, and ChatGPT-style generative answers, often inside the same buying decision. Each one rewards a different optimisation discipline, and most businesses are only doing the first.

At [Refrakt](/), we build for all three, SEO, AEO and GEO, as one connected visibility stack. Here's what each one actually means in 2026, and how to rank in each.

SEO, Search Engine Optimisation

SEO = getting your business's website to appear in search results.

This is the foundation, and it isn't going anywhere. When someone Googles "best management consulting firm UK" and clicks the McKinsey link, that's SEO doing its job.

How it works:

• Identify high-intent keywords and map them to service pages
• Build authoritative backlinks and optimise on-page content

Pros:

• Proven, steady traffic driver
• Builds long-term authority and brand equity

Cons:

• Slow to show results
• Vulnerable to algorithm updates

How to rank higher:

• Focus on high-intent keyword clusters specific to your service
• Run regular technical audits and refresh content quarterly

If your site is still invisible in classic Google results, fix this first. [Our SEO service](/seo) is built around the same playbook we use for our own rankings.

AEO, Answer Engine Optimisation

AEO = getting your expertise extracted into answer boxes and AI Overviews.

When someone asks "what's the best consulting firm in London" and Google's AI Overview pulls a 60-word answer naming McKinsey, BCG and Bain, that's AEO. The user often never clicks a link, but the brands quoted win the mindshare.

How it works:

• Provide concise, direct answers to the questions your clients are asking
• Use FAQ and How-To schema for structured data

Pros:

• Instant authority and brand visibility
• Strong for voice and mobile queries

Cons:

• Some users get the answer without clicking through
• Snippet positions change frequently

How to rank higher:

• Answer questions in 40 to 60 words under clear headings
• Add structured schema to FAQ and How-To content

The brands cited inside AI Overviews are the ones the next buyer trusts, even when traffic doesn't move.

GEO, Generative Engine Optimisation

GEO = getting cited by name in detailed AI-generated recommendations.

When someone asks ChatGPT "which London consulting firm should I work with" and the answer lists MBB firms by name, that's GEO. This is the newest layer of search, and the one most agencies still don't understand.

How it works:

• Publish clear, well-structured thought leadership with citations and data
• Build presence on the credible sources AI models pull from

Pros:

• Early-mover advantage in AI search
• Positions your firm as a trusted authority

Cons:

• Hard to measure direct impact
• Requires multi-platform presence beyond your website

How to rank higher:

• Create factual, entity-rich content following E-E-A-T principles
• Contribute to sources AI frequently references: industry reports, forums, publications

This is exactly what our [GEO and AI search service](/geo-ai-search) is built for, getting your brand named inside ChatGPT, Perplexity, Claude and Gemini answers.

So Which One Should You Be Doing?

All three. They're not alternatives, they're layers.

• SEO captures the buyers who still type into Google and click links
• AEO captures the buyers who read the AI Overview and move on
• GEO captures the buyers who ask ChatGPT and never touch Google at all

A business that only does SEO in 2026 is optimising for a shrinking slice of search behaviour. A business that does all three becomes the answer in every layer of how people now find services.
