I got the following email from Google Search Console a few days after implementing MEC:
Top Errors
Errors can prevent your page or feature from appearing in Search results. The following errors were found on your site:
Missing field “location.address”
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 “offers.validFrom”
Missing field “performer”
Missing field “offers.availability”
Missing field “location.name”
Missing field “offers.price”
We recommend that you fix these issues when possible to enable the best experience and coverage in Google Search.
I have no need to use those parameters in MEC for my events and wish to keep them empty. But I cannot have them be impacting my searches on google. Please advise.
