LLM Indexing Guide

AI models don't crawl the web like search engines. Learn how to make your website truly readable and understandable by large language models.

How LLMs "See" Your Website

Unlike Google, LLMs don't crawl your site in real-time. They learn from training data, which may include cached versions of your website, Wikipedia, news articles, and other sources.

Google Crawling

  • • Real-time website crawling
  • • Indexes page by page
  • • Follows links dynamically
  • • Updates index regularly

LLM Training

  • • Learns from training datasets
  • • Knowledge has cutoff dates
  • • Synthesizes information
  • • May have outdated info
