Pinterest ad previews now cover promoted pins only, using a new Has Been Promoted field on Pin Media Entity.

The Ad Image Preview and Ad Video Preview reports previously mirrored every image and video attached to any pin on the connected ad account — including pins that were never used in an ad. On large accounts that is the overwhelming majority of the catalogue, so previews took hours to extract and most of what they stored was not an ad creative.

Both reports now mirror media of promoted pins only. Pinterest reports whether a pin has ever been promoted, and Improvado carries that flag through to Pin Media Entity as the Has Been Promoted field.

What changes for you

• Fewer new previews. Previews are no longer created for pins that have never been promoted. Previews already stored are not removed, so existing rows and links keep working.
• New field on Pin Media Entity. Has Been Promoted is what the preview reports read to decide which media to mirror, so it has to be collected on Pin Media Entity for them to return anything. It has already been added to every extraction that feeds a preview report; select it yourself when you set up a preview report from now on.
• Preview links were refreshed once. Preview files are now stored per medium rather than per pin, so a pin carrying several images or videos gets a separate file for each. Links generated after this release differ from the ones stored before it; the earlier files remain available.

If you need media for organic pins

These two reports are scoped to advertising creatives. Media for pins that were never promoted is still available through Pin Media Entity, which continues to cover the full pin catalogue and carries the source image and video URLs.
