Ranking in ChatGPT means being cited inside its answers, not holding a link. Here are the seven proven GEO tactics that lift AI citations, with the research.

AI citation rates swing day to day, so naive before-and-after tests mislead. Here is a 6-step statistical framework for sample size, control groups and significance.

We assessed 23 UK AI SEO and GEO agencies against a 5-question RFP filter testing non-fakeable capabilities. Only 6 passed all five. The filter cuts a typical long-list by two-thirds.

We synthesised public ChatGPT prompt-leak reporting, peer-reviewed retrieval research and our 50-query AiBoost behaviour test into a single 14-factor map with confidence scores. 5 high-confidence, 6 medium, 3 low.

We mapped 12 ranking signals against classic SEO and generative engine optimisation. 5 transfer cleanly, 4 do not, and 3 flip. Anchored to Ahrefs 2025, Profound 2025, arXiv 2024 and AiBoost UK panels.

We A/B tested two identical UK pages, one with FAQPage and Article schema, one without, across 30 buyer-intent prompts on ChatGPT browsing mode. The schema variant was cited 2.35x more often. Full ablation data.
