I am trying to create pins from my Etsy shop that will have the "shop" bubble on it because I want my pins to appear for people who are specifically searching on Pinterest to shop. I just recently learned that this is called a "product pin" and that in order to get my pins to be product pins I need to validate my shop's URL. I tried validating the URL of my shop, and it doesn't work. But I can validate the URL for an individual product. Pinterest says that my URL is validated, but my pin is still not a product pin. Am I missing something? Does it take a day to two for the pin to convert to a product pin?
