Common Questions
All Q&A → What is AI search optimisation?
AI search optimisation is the practice of structuring your website, content, and brand presence so that AI platforms like ChatGPT, Google Gemini, Perplexity, and Google AI Overviews cite or recommend your business. It includes GEO, AEO, and LLMO.
How much does it cost?
UK pricing ranges from £1,500 to £25,000/month. Small business: £1,500-£3,000. Mid-market: £3,000-£8,000. Enterprise: £8,000-£25,000+. Most agencies offer initial audits from £500-£2,000.
What's the difference between GEO, AEO, and LLMO?
GEO focuses on AI-generated answer citations. AEO targets zero-click answers and featured snippets. LLMO specifically optimises for LLM platforms like ChatGPT and Claude. All fall under AI search optimisation.
Do I need an agency or can I do it myself?
Basic optimisation is possible in-house: clear headings, schema markup, consistent brand descriptions, allowing AI crawlers. Agencies add proprietary audit tools, cross-platform testing, and ongoing monitoring. Most businesses benefit from at least an initial audit.
How long does it take to see results?
Initial improvements to structured data and crawlability can take effect within weeks. AI citation improvements typically appear in 2-3 months. Significant visibility gains across multiple AI platforms usually take 3-6 months of consistent work.
