Generative engine optimization (GEO)
GEO is the work of making your brand the one AI engines name and cite. The term comes from a 2023 Princeton-led research paper that tested how content changes affect visibility in generative answers. The short version: be specific, be quotable, and be discussed by others.
What the research found
In the original GEO study (Aggarwal et al., 2023), adding statistics, quotations from credible sources and citations to a page raised its visibility in generative answers by up to roughly 40% in their benchmark, while keyword stuffing did not help. Treat the exact figure as a lab result; the direction has held up in practice.
Tactics that work
- Answer the question in the first two sentences. Engines lift concise, self-contained passages.
- Use numbers with sources. Prices, dates, test results. Vague claims are rarely quoted.
- Get onto the lists engines read. “Best X for Y” articles, comparison pages, review sites, Reddit and niche forums are frequent sources for recommendation prompts.
- Keep facts consistent everywhere. Same name, pricing and positioning on your site, profiles and directories.
- Let AI crawlers in. Check robots.txt for GPTBot, OAI-SearchBot, PerplexityBot and Google-Extended. Blocking them can remove you from live answers.
- Use structured data (Organization, Product, FAQ) so entities are unambiguous.
- Measure with fixed prompts. Without a tracker you are guessing. See the tools.
GEO vs SEO
| SEO | GEO | |
|---|---|---|
| Goal | Rank a page in a list of links | Be named or cited inside an answer |
| Unit of success | Position, clicks | Mention rate, citations, share of voice |
| Off-site signal | Backlinks | Mentions on trusted sites, even unlinked |
| Measurement | Rank trackers, Search Console | Prompt-based AI trackers |
