Either “offers”, “review”, or “aggregateRating” should be specified

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

Google recommends disabling the schema to your product category archives. The Product Schema is only for the actual product, and not for anything else. You can check this link for more information:
https://developers.google.com/search/docs/data-types/product#guidelines

To fix this issue, you may need to enable the Remove Snippet Data option in Rank Math > Titles & Meta > Product Brands as that removes the product schema from those pages.

Once done, you can revalidate the issue in your Google Search Console, and give Google some time to recrawl your site.

Hope that helps.

Thank you.
