Welcome to the Q&A Forum

In the top right you will see "MOZ PRO" click on that. This will bring you to your home page that will have a listing of your website. Click the "View" button next to it on the right hand side. This will bring up your dashboard and on the left hand side you will see a menu like this: Dashboard Search Social Links Brands & Mentions Click on the one that says "Search." From there, scroll to the very bottom and on the right hand side there will be a list of the errors you're looking for.

Thanks, I'll get the Pinterest meta tag posted to my website right away.
