Your home feed is a blend of Picked for you Pins and Pins from the people, topics and boards you follow. You can hide individual Pins from your home feed or unfollow the board, topic or account that the Pin came from. This helps Pinterest understand the kinds of Pins you do or don’t want to see. If you hide a Pin on accident, you can unhide it.
To learn more about why you’re seeing a Pin in your home feed, click the ellipsis icon in the bottom-right corner of the Pin. You’ll be given a reason for why you’re seeing the Pin.
To edit all of your recommendations at once, you can tune your home feed to turn on or off recommendations that you do or don’t want to see.
