Pinterest: How to Use the Homefeed Tuner to Manage Your Recommendations

Users can stop boards and pins from being used for content suggestions

By default, as you browse and save Pins to boards on Pinterest, the Pinterest application will use your activity to add similar content to your home feed going forward. If you’re seeing lots of content on your home feed that you’re not interested in, you can use the platform’s “Homefeed tuner” feature to “turn off” recommendations related to specific boards you’ve created and Pins you’ve looked at.
