Google webmaster tools: Pinterst/Blocked resources

If these resources are not hosted on your site, you can ignore those blocked resources, as you won’t be able to make any changes so that content can be indexed. Since the content isn’t hosted on your site, you also don’t really have any interest in having it indexed.

In the example you posted above, that Pinterest widget page shouldn’t really be indexed; it’s only used to server widgets or sharing buttons on your site, and doesn’t include any meaningful content.

When reviewing the Blocked Resources report, you’ll want to focus on things that are hosted on your site, and that you would like Google to index.

I hope this helps.
