The 3 Pillars of ChatGPT SEO
To truly optimize for Large Language Models (LLMs), you must move beyond keywords and focus on Entity Density and Contextual Authority.
1. Technical Health (The Foundation)
ChatGPT cannot cite what it cannot read. Unlike Google, which can parse messy HTML, LLMs prefer structured, clean code.
- llms.txt: This is the new robots.txt. You must have a file at yourdomain.com/llms.txt that explicitly tells AI agents who you are and where your most valuable content lives.
- JSON-LD Schema: This is non-negotiable. Your "About" page must use Organization schema to define your brand entity, linking to your social profiles (sameAs) to triangulate your identity.
2. The "Golden Answer" Format
LLMs predict the next word. To be picked as the answer, your content must look like the best possible completion of a user's prompt.
- The Inverted Pyramid: Start every section with a direct, 40-word definition or answer. (e.g., "ChatGPT SEO is the process of optimizing web content to appear in generative AI responses...")
- Fact-Checking Layers: LLMs hallucinate less when you provide data. Follow your claims with citing sources or internal data tables.
3. Entity Interlinking
Don't just link to "pages"; link to "concepts." If you mention "Schema Markup," link it to a reputable definition (or your own glossary). This builds a Knowledge Graph that helps the AI understand the relationship between your services and the user's problem.
Pro Tip: Use EZY.ai to automatically generate your llms.txt and validate your Entity Graph in seconds.
