Pinterest indexes the description content.
Images are not indexed. Its the related content - in the description that's being indexed. So in the example of the description it's weighted to be related more to popsugar. It's also @tagged. Also, SM2 does not have an option to add a description even if you are using your own images.
It's like a hole in creating my brand if I'm including someone elses content in my ads (pins).

So it would be good if SM2 could replace the description when the pin is created, with content related to my site or board.
I have been deleting the description and or replacing it manually without any issues. The problem is that it's manual process to do all the cleanup.
