Because it is simple, visible, and easy to implement, while the harder work of earning citations usually lives in content quality and third-party evidence. The study shows hype is not the same thing as outcome.

## Methodology

Built from HTTP scans of 37,894 AI-cited domains, linked to 337,362 citations and 882 citation snapshots in the Trakkr corpus.

## Direct Answer

Mostly because it is simple, visible, and easy to implement, while the harder work of earning citations usually lives in content quality and third-party evidence. The study shows hype is not the same thing as outcome.
