Block Amzn-User in robots.txt

User-agent: Amzn-User
Disallow: /

Blocking a search or user-triggered bot removes your pages from that assistant's answers. To opt out of model training only, block the operator's training crawler instead.

Analysis using this data

  1. Who blocks AI crawlers? What 10,000 robots.txt files revealPublishers block training, not answers; half of all blocklists leak; Cloudflare writes the most common AI policy.
  2. The opt-out asymmetry: you can block the small AI engines, not the big oneThe AI surfaces with the most users are the ones publishers can't refuse and can't measure.

  2. Link to this page (https://kuldeep.cc/data/ai-search/crawlers/amzn-user), not to the download file, so readers can check the source of every number.
  3. Include the date. These figures change; say “as of Oct 29, 2026” or link to the version you used.
  4. Mark changes. If you filter, recalculate or chart the data yourself, say so (“analysis based on data from…”).
  5. Cite the original source for single figures when you quote one reported number; it is linked in every row.
