How do you verify that a product claim survives the path from page to feed?

Disclosure: I work on Verity Score, a product-data auditing tool.

A concrete example for a catalog review: a shopper needs headphones that help colleagues hear them during calls in a noisy office. A listing that only says “noise cancelling” leaves an important distinction unresolved: noise reduced for the listener versus background noise processed in the microphone signal.

This is an illustrative listing, not a defect measured on a merchant's site. Sony's WH-1000XM6 documentation separates listening and call features, which makes it a useful example of model-specific evidence.

The review method I use is:

1. Record the purchase requirement and its source.

2. Find supporting documentation for the exact model and variant.

3. Check whether the visible page explains the relevant function.

4. Compare that with the data Merchant Center actually receives instead of assuming a page edit propagated through the connector.

Google supports an optional `product_detail` field for technical specifications, with rules against keyword lists and duplicating details already supplied in other attributes. It is a possible destination for a missing technical fact, not a universal requirement or a ranking guarantee.

For teams managing multiple feeds: how do you compare received values with the source catalog? Is that part of routine monitoring or something you investigate after an issue appears?
