What you can Pin
You can Pin:
Images that are at least 100px in one dimension (height or width) and at least 200px in the other dimension
Videos from YouTube, Vimeo and Kickstarter – both from their sites and embedded in yours (using standard embed codes)
Note: We check with Flickr before Pinning images hosted there. When adding Pins from Flickr, you might see an image turn gray and become un-Pinnable – this is usually because someone used an image from Flickr that was marked as private by its owner.
You put in an image! The Pin It button won't work if you don't give it an image to Pin.
You put in the fully-qualified URL for the page and image you want to Pin, including the http:// part.
Note: To check this, copy the URLs from the form, paste them into a new browser tab and make sure they load. If they won't load in your browser, we can't Pin them.
If counters aren't showing next to your Pin It button or if you see a the fullscreen version of the Pinterest add a Pin dialogue, go back to the widget builder and check that:
You didn't choose the No Count version when you made the button
Note:To conserve bandwidth we don't maintain a persistent connection between the Pin It button and Pinterest. The counter will increment when you reload the page after Pinning. There may be a delay, depending on internet conditions.
You don't have to include our script in the body of your page. If you'd rather load it asynchronously with the other third-party tags you're using, you can try this:
Note: As long as our script fires after all the Pin It buttons have been rendered into the document, you should be fine. If you’re loading other asynchronous scripts, feel free to include them in the array of scripts, third line from the bottom.
Some people have asked if we have a callback option or a way to dynamically create Pin It buttons. We don't have these yet, but we know you want more advanced options and are working on it!
Data Pinterest can collect
If someone goes to your website and you have a Pin It button (or other Pinterest widget) on your site, we can use that info to personalize their experience on Pinterest. For example, we might suggest more recipe Pins to someone who visits a bunch of cooking sites.
We think using this data will help Pinners find more things they're into, but if people aren't interested, they can turn off personalization from their settings. And of course, we also support Do Not Track.
