The pages ChatGPT pulls from

A few of the most-cited reddit.com pages behind these answers.

How we measured this

  • We asked ChatGPT brand-free shopping questions across 18 product categories and recorded every source URL it cited — 293,240 citations in all.
  • This page counts how often reddit.com showed up among them. Citation counts are for the public category studies only, not any private client work.
  • A citation is ChatGPT surfacing the source. It is not an endorsement, a link, or traffic.
  • One engine, one country, one point in time. The shelf, and who writes it, moves.
