Signal
Facts per token, complete against peers
Your listing packs specific, verifiable facts per token (specs, price, GTIN, availability, policy) and fills the comparable attributes the top listings in your category expose, so an agent has real substance to decide on rather than superlatives.
Per-platform status
Where a platform documents relevant behavior, its status and source are shown. Undocumented platforms show "unknown" - honest unknowns, never invented.
| Platform | Status | Notes | Source |
|---|---|---|---|
| ChatGPT | Partial | Selection considers structured metadata such as price and description plus other third-party content, and the feed bars placeholder values. There is no token-density concept. | Source (opens in new tab) · verified 2026-08-28 |
| Gemini / Google AI Mode | Partial | Google documents that fuller, accurate attributes matter, which supports filling comparable fields, but has no token-economy concept. | Source (opens in new tab) · verified 2026-09-18 |
| Perplexity | Unknown | Not documented by this platform. | - |

Lead every machine surface with specs, price, GTIN, availability, and policy; list the attributes the top 3 competing listings expose and fill your gaps truthfully with measurable facts, not superlatives.
