What this ranking means
Ranked in tiers: documented shopping integration, discovery integration, explicit robots permission, no sampled robots block, restrictions, then unknowns. Equal categories share a rank. Integrations are limited to the named partner route; they do not imply access for every agent. These are 51 major US retailers from the Billions sample, not an exhaustive list or a ranking by revenue.
We check ChatGPT-User, Claude-User, Perplexity-User and GoogleAgent-Shopping against /, /cart, /checkout and /account. Training crawlers are excluded. Specific endpoints may differ; robots.txt expresses crawl policy, not enforcement or successful purchases. A partner API can work even when browser agents are restricted.
Primary policy and integration records are reviewed separately and expire from ranking after 14 days without review. No sampled block is not permission to buy. Failed policy retrieval is marked Not verified. Earlier audit findings stay dated and separate from our current observations.
