Product information shapes what a buyer can understand before they buy. In an AI-assisted journey, that information may be summarised, compared or combined with information from other sources.
The useful starting point is consistency: do the product page, the specifications and the structured data describe the same product? Are model numbers, attributes and availability unambiguous?
Structured data can make an explanation more explicit. It does not make an inaccurate statement correct, nor does it guarantee a recommendation. The underlying information needs to be useful and defensible.
I would prioritise the attributes that can change a decision. A well-maintained explanation of compatibility, constraints and suitability often gives a team a more concrete improvement task than producing more generic content.
