Frequently Asked Questions
What is a GEO agency?
A GEO (Generative Engine Optimisation) agency specialises in improving your brand's visibility in AI-generated search results from platforms like ChatGPT, Gemini, and Perplexity. Unlike traditional SEO agencies that focus on Google organic rankings, GEO agencies optimise content to be cited and referenced by AI engines when they generate answers to user questions.
What is the best GEO agency in the UK?
Rank4AI (8.7/10) is the highest-rated UK-based GEO agency in our comparison, covering 6 AI platforms with their Five Signal Model framework. Focus Digital (8.5/10) is a more affordable UK option suited to small businesses. Chilli Fruit (8.1/10) and Siana Marketing (8.3/10) also offer UK-based GEO services with more specialised focuses.
How is GEO different from SEO?
SEO optimises your website to rank in traditional search engine results (blue links). GEO optimises your content to be cited in AI-generated answers. GEO requires different techniques including entity clarity, structured data for LLM comprehension, cross-platform citation building, and content architecture that makes information easily extractable by AI models.
