To keep search engines like Google and Yahoo! from showing your Pinterest profile, you can change your privacy settings.
1Click your name at the top of Pinterest, then Settings
2Switch Search Privacy from No to Yes
3Click Save Settings
Although we can hide your profile, we can't always hide your name, especially if other people have Pinned your Pins. For extra privacy, you can change your name or use secret boards.
After you edit your privacy settings or name, it’ll take several weeks for the search engine to update those changes. If you’ve turned on the search privacy setting and you’re still seeing your profile in search results, you can ask Google to remove a page more quickly.
