Expanded explanation

## Why AI Crawlers / LLM Crawlers Matters for SEO

Allowing AI crawlers is now a strategic choice. Being crawled is a prerequisite for being cited, block GPTBot and ChatGPT can't reference you. These crawlers behave differently to Googlebot, so understanding the distinction matters for your AI visibility strategy.

## How AI Crawlers / LLM Crawlers Works

Crawlers visit pages, extract content, and feed it into training datasets or real-time retrieval systems (RAG). Different crawlers serve different purposes: some collect training data, others power live knowledge retrieval. Robots.txt is the primary control mechanism for allowing or blocking specific crawlers.

## Common Mistakes

- Blanket-blocking all AI crawlers in robots.txt without understanding the trade-off
- Not monitoring which AI crawlers are accessing your site via log file analysis
- Assuming blocking AI crawlers protects valuable content, it more often reduces visibility
