After these updates, there are a couple things we’ll do to improve Promoted Pins (we’re still only testing in the U.S.):
1. We want to help advertisers better understand how their Promoted Pins are doing. For example, an advertiser may want to know how often their ads are showing on Pinterest or how many people bought a product after clicking on a Promoted Pin. In the future, we’ll report that info to them.
2. We also want the Promoted Pins you see to be relevant to you and come from brands you’ve shown interest in. We hope to incorporate information advertisers share with us so that we can show you Promoted Pins that don’t feel random or distracting.
If you don’t want us to use info from advertisers to personalize the Promoted Pins you see, you can change your account settings. We’ll continue to support Do Not Track for personalization on Pinterest, as well.
