Hello,
Showing CollectionPage schema on Product archive pages is also not a good idea, Google suggests using Product on the category pages: https://i.rankmath.com/yHTG0u
https://developers.google.com/search/docs/guides/sd-policies#multiple-elements
As per the Google norms you should only include the data in snippet which exists on the page:
The structured data on the page should describe the content of that page. You should not create blank or empty pages just to hold structured data; nor should you add structured data about information that is not visible to the user, even if the information is accurate.
Since product category pages don’t contain all the product information like brands, reviews etc, we are not adding it in the archive page schema.
As individual product page exists on your site and Product schema is added in the individual product pages, I would suggest you not to add Schema data on the archive pages as it is irrelevant and not needed. You can remove schema data from archive pages by enabling the Remove Snippet Data option in Dashboard >> Rank Math >> Titles & Meta >> Product Categories.
Hope that helps. Thank you.
