Top 6 Generative Engine Optimisation (GEO) Agencies in the UK (2026)

Introduction

The way people search is changing - fast. In 2026, Generative Engine Optimisation (GEO) is the next leap beyond SEO. Instead of ranking just for blue-link results, brands now compete to appear in AI-generated answers from ChatGPT, Perplexity AI, and Google’s Search Generative Experience.

At Appear Online, we’ve been at the forefront of this shift. We help businesses prepare their sites to be referenced, cited, and recommended by AI models - not left behind by them.

‍

🤖 What Is Generative Engine Optimisation (GEO)?

A generative engine optimisation service optimises content for AI-powered search engines like ChatGPT and Google SGE so your brand appears in generated answers, not just traditional search results. It builds trust signals - structured data, expert citations, and author credibility - so AI systems recognise your business as a reliable source.

This approach complements traditional SEO by focusing on entities, E-E-A-T alignment, and AI-readable content markup. When done right, GEO creates visibility across both human and machine search landscapes.

Difference Between AI SEO, AEO & GEO

Before diving deeper, here’s how GEO differs from other AI-related optimisation models.

AI SEO, AEO (Answer Engine Optimisation), and GEO are often confused, but each serves a distinct purpose. AI SEO optimises content using AI tools to improve rankings. AEO focuses on voice search and direct answers to user queries. GEO, the next evolution, ensures content is recognised by AI search engines and featured within generated responses from systems like SGE or ChatGPT. Below, we’ve broken down the key differences in purpose, method, and outcomes.

Key Aspects of a GEO Service

The core principles of GEO align with trust, clarity, and AI readability. We expand each pillar below to show how we approach them at Appear Online.

• Focus on AI answers: Our goal is to get brands featured in AI-generated responses from tools like ChatGPT and Perplexity AI.
  
  
• Structured content: We optimise your site architecture and headings for AI interpretation.
