Today when I converted my Pinterest from a personal account to Pinterest I spent several hours searching and trying the help section of both Pinterest and Typepad without any luck, and trying to verify my blog. Then I read how to verify your blog for google and tried the same thing for Pinterest, and it worked. So hopefully this will help someone else save time – and hopefully it will work for you as easily as it did for me.
If you are just now converting follow all the steps and when you get to the verification step follow the directions below
If you have already converted from personal to a business file then go to your settings and were unable to verify at the time… go to your settings and scroll down until you see the website and verification.
Then you will see a screen like this
Click on Download the HTML verification file (each browser might be different, mine saved it to my computer). Then I went to my Libary Tab and clicked on Files and uploaded the saved verification file to my files.
