Why it matters
Google's merchant listing guide says Product rich results only support pages that focus on a single product, or on several variants of the same product. Said at Search Central Live: structured data also points Google at the pertinent data and stops its systems pulling in extraneous information such as the prices of related products, while Google's own extraction sometimes fails to find a page's main content.
How to meet it
Generate Product and Offer markup only for the product the page is about, and give recommendation, recently-viewed and bundle carousels no Product markup.
How to test it
The Rich Results Test on product pages lists exactly one product (or one product group with its variants).
How Regensbot covers it
Decided from one URL.
An audit reads the response, the headers, the HTML, robots.txt, the sitemaps and the structured data, and the finding shows the evidence it saw.
