Why GEO is its own discipline
Traditional SEO optimizes for ranking in a list of blue links. Visitors click and land on your page. GEO optimizes for being quoted inside an AI's answer — visitors may never click, but your brand appears as the cited source. The two practices overlap (good content helps both) but the optimization tactics diverge in important ways.
What AI engines actually quote
Studies of Perplexity and ChatGPT citations consistently show preferences for: (1) Pages that answer the question in the first paragraph, in 40–80 words. (2) Pages with statistics, dates, and specific numbers (uncertainty is filtered out). (3) Pages with structured schema markup (FAQ, HowTo, Article) that makes the question-answer mapping explicit. (4) Pages from domains the engine has previously cited successfully.
Practical GEO tactics
Use question-led H2s ("What is X?" not "About X"). Put the direct answer in the first paragraph. Add stats every 150–200 words. Use FAQPage schema with single-question pages. Cite your sources inline (the engines reward this). The GEO guide walks through the structural patterns we've found increase citation rate.
