Signal
Offer cost legibility
An agent can read your full cost on a cold product page - the current price and any sale in parseable text with currency and tax, plus shipping, fees, unit price, and any free-shipping threshold - and every figure matches checkout.
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 | Cost reaches ChatGPT through feed fields (price, sale_price, shipping_price, shipping) rather than page parsing, and checkout returns taxes, fees and totals. | Source (opens in new tab) · verified 2026-09-18 |
| Gemini / Google AI Mode | Partial | Price and currency are required and must match in three places. Google does not frame cost as something read off a cold product page. | Source (opens in new tab) · verified 2026-09-18 |

How to act on this
With images suppressed, confirm the current price, sale window (priceValidUntil), currency, tax treatment, shipping, fees, unit price, and free-shipping threshold are all present as real numbers and match checkout.
Related checklist items
- Make total landed cost (price + shipping + fees) readable before the agent commits to checkout. Selection
- State unit pricing (per 100 ml, per count, per kg) where it aids comparison. Selection
- Put the current price in parseable text/markup, never only inside an image. Selection
- Make currency and tax treatment explicit near the price (e.g., incl./excl. VAT). Selection
- Make sale pricing and its validity window legible, matching checkout. Selection
- Show shipping cost before checkout, not only at the payment step. Selection
- State free-shipping / free-returns thresholds as concrete numbers. Selection
