How ChatGPT ”Understands” Websites in SEO-like Contexts

Unlike Google, ChatGPT doesn’t crawl the web in real time. It understands web content through:

Its training data (snapshot from before 2024–2025)
Information you or plugins/tools feed to it
Structured and well-formatted content that can be read and embedded into AI tools or APIs

To make ChatGPT (or tools built on it) understand your site better for SEO, discovery, or integration purposes, focus on the following:

Use JSON-LD schema markup for:
- Article, Product, FAQ, BreadcrumbList, LocalBusiness, etc.
Helps AI tools and LLM-based bots (and Google!) extract meaning.
Example:

Why it matters: This is readable by LLMs when the page is scraped, and it makes your content understandable in a machine-readable way.

Use semantic HTML elements: <article>, <section>, <header>, <main>, <nav>, etc.
Prioritize meaningful text inside <h1>, <h2>, and <p> tags.
Avoid content hidden by JavaScript (unless server-rendered).

Submit sitemaps to Google/Bing and ensure LLM-based bots (like Perplexity, You.com, etc.) can crawl your site.
Allow crawling in robots.txt:

If you offer services/tools, having an OpenAPI spec or well-documented API increases the chance of AI tools integrating or understanding your service capabilities.

Use natural language, FAQs, tutorials, and explainer content — this is easy for ChatGPT to ”learn from” when ingested by AI search tools.
Tools like Perplexity, Phind, and AI-based assistants that crawl in real-time prioritize informational content written clearly and structured.

If your goal is to be discoverable by AI tools using ChatGPT/GPT-4/LLMs:

Perplexity.ai: Optimize for their search engine with clear, authoritative content.
ChatGPT + Browsing: Ensure your content is crawlable.
OpenAI Plugins or API integration: If you expose a service.
RAG (Retrieval-Augmented Generation): Some companies feed websites into LLMs using embeddings — your structured content is crucial here.

Area	Action
Schema.org	Add structured data (JSON-LD) for clarity
Semantic HTML	Use meaningful tags and avoid content hidden by JavaScript
Helpful content	Publish Q&A, use cases, comparisons, tutorials
Allow Crawling	Ensure `robots.txt` and sitemap allow bot access
APIs/Docs	Expose developer-friendly docs if relevant
Embeddings/LLMs	Consider RAG-style ingestion if building custom ChatGPT tools
