Reply To: Structured Data Errors In Webmaster Tools

[Bart Pluijms]

I am having the same error for “Blog is not a known valid target type for the mainContentOfPage property.” on a site.

I’ve also the following error for the search result page which is probably related:
“SearchResultsPage is not a known valid target type for the mainContentOfPage property.”

I hope you can find a solution for this.

Best regards,
Bart
