Modern AI search optimization requires understanding how ChatGPT and other LLMs process content

The era of "10 blue links" is ending. Today, 50% of product searches start on Amazon or AI platforms, not Google. You might rank #1 on Google, yet be completely invisible when a user asks ChatGPT, "What is the best tool for X?" This guide covers Generative Engine Optimization (GEO)—the new art of optimizing for Answer Engines.

1. Adopt an "Answer-First" Content Structure

Organize content with clear hierarchies so AI can quickly extract and cite your answers

LLMs are lazy. They prefer content that is easy to summarize. Stop hiding your main point.

Use Answer Capsules: immediately follow every H2 header with a direct, 50-word definition before expanding into details. If you answer the user's intent instantly, the AI is more likely to cite you as the source.

2. Optimize for "Entity Density"

Search engines used to look for keywords; AI models look for Entities (Concepts, Brands, People).

Ensure your "About Us" page clearly defines who you are using simple, factual language. If the AI doesn't understand your entity, it won't recommend you.

3. The Power of "Quotable" Statistics

AI models prioritize sources that provide unique data points to back up claims. To get cited, you must be the source of the truth.

Publish original benchmarks or industry stats. When ChatGPT needs to prove a point, it will link to the data source.

4. Technical GEO: The llms.txt File

Just as robots.txt tells Google where to go, a proposed standard called llms.txt helps AI crawlers find your most important content.

Create a simple text file listing your top 10 most valuable guides and link to it from your footer.

5. Measuring Success: Share of Model (SoM)

You can't track clicks easily in zero-click environments, so you must track mentions. This is called "Share of Model".

Doing this manually is impossible.
