Ads are Pins that businesses pay to promote. They appear in your home feed and search results.
If you see a product you want, you can buy it. Click the Pin to be taken to the advertiser's website where you can complete your purchase.
If you see an ad that doesn't interest you, you can hide it. Pinterest uses your feedback to make sure you see more relevant ads in the future.
If you don't want to see ads from a specific advertiser, you can block the advertiser's Pinterest profile. You can block up to 1,000 advertisers.
While you can't turn off ads completely, you can limit the kinds of information we use to pick which ads you see.
