## Why it matters

AI systems need to link to specific facts, not just entire pages. When AI cites a source, a deep link to the specific section increases response credibility and allows the user to quickly verify the information.

## In practice

GitHub documentation automatically generates anchor links for every heading, enabling precise citation. When ChatGPT references GitHub docs, the user goes directly to the relevant section.

## How be1st checks it

Checks whether key facts and information on the page have direct URLs (anchor links): whether headings contain ID attributes, whether deep links to specific sections exist, and whether specific information can be shared directly. The check counts headings with an id (at least 3), elements with an id (at least 5) and anchor links (at least 2).
