Google Search Console warnings

[idigbooks]

I received an email today from Google Search Console that reads:

To the owner of https://idigbooks.square.site/:

Search Console has identified that your site is affected by 7 Products issues:

Top Warnings

Warnings are suggestions for improvement. Some warnings can affect your appearance on Search; some might be reclassified as errors in the future. The following warnings were found on your site:

Missing field "priceValidUntil"

Missing field "review"

Missing field "sku"

Missing field "url"

No global identifier provided (e.g., gtin, mpn, isbn)

We recommend that you fix these issues when possible to enable the best experience and coverage in Google Search.

Should I be concerned? How would I go about fixing these anyway?

Thanks for your post, @idigbooks.

For now you don't really need to worry about these; they affect how products are display in search but don't affect indexing or ranking. If that ever changes then I would expect that we'll make some changes on our end in advance to support those.
