Core Concepts

Generative Engine Optimization (GEO)

Definition

The practice of optimizing web content so that AI search engines (ChatGPT, Perplexity, Claude, Gemini) cite or recommend it when answering user questions.

Also known as: AEO, AI SEO, LLM SEO

Generative Engine Optimization (GEO) distinguishes AI search optimization from traditional SEO. Traditional SEO targets keyword ranking in blue-link results. GEO targets citation in natural language answers — being the brand in "The best X are A, B, and C" responses.

Core GEO Techniques

  1. AI crawler accessibility — Allow GPTBot, ClaudeBot, PerplexityBot in robots.txt
  2. llms.txt — Brand context file at /llms.txt that summarizes who you are for LLMs
  3. FAQ schema — FAQPage structured data for question-answering content
  4. TLDR-first writing — Direct answer in the first sentence of every section
  5. Entity building — Consistent brand mentions across credible external sources

Brand Impact

Brands that invest in GEO see measurable citation rate increases within 60–90 days of fixing technical barriers (robots.txt, missing llms.txt) and adding structured content. A typical improvement: 12% → 34% citation rate after addressing crawler access and adding FAQ schema to top product pages.

Frequently Asked Questions

Is GEO the same as AEO (Answer Engine Optimization)?
The terms are used interchangeably by most practitioners. AEO predates GEO and was coined before large language models dominated AI search. GEO is now the more common term.
Does GEO replace SEO?
No. Traditional SEO still drives significant traffic through Google's link-based results. GEO is an additional layer — optimizing for citation in AI answers alongside organic ranking.
How long does GEO take to show results?
Technical fixes (robots.txt, llms.txt) can show results within weeks as AI crawlers re-index. Content changes take longer — typically 60–90 days for citation rate to reflect new structured content.
