Thank you for sharing this. I kept trying to validate for rich pins using my home page URL. Rich pins are important for Pinterest business and do not know why this small bit of info was not included in the training here at WA.
I've followed the exact steps to enable rich pins but with the validator I get an error "We were unable to retrieve any data from your URL", any ideas?
Ahh just after asking I kept clicking "Validate" and the message changed to something like "The Pinterest server is having trouble", then I clicked it again (a few times) and it finally went through and got validated yay!
This was a helpful tutorial. I have a Pinterest account, but I will remember this tutorial when I get further into my posting on my site and use this feature. Thanks for the tutorial!
