How does Facebook decide which ads to show me and how can I control the ads I see?

We want the ads you see on Facebook to be as interesting and useful to you as possible. To decide which ads to show you, we use:

Information you share on Facebook (example: posts or comments you make) and your activity on Facebook (such as liking a Page or a post, clicking on ads you see).
Other information about you from your Facebook account (example: your age, your gender, your location, the devices you use to access Facebook).
Information advertisers and our marketing partners share with us that they already have, like your email address.
Your activity on websites and apps off of Facebook.

For more information on the information Facebook receives and how we use it, visit our Data Policy and Cookies Policy.

You have several ways to control which ads we show you:

Adjust your ad preferences. Click or near the top-right corner of any ad on Facebook, and select Why am I seeing this? You’ll see an explanation of why you’re seeing the ad, and you can choose to hide all ads from that advertiser. Select Manage your ad preferences to see more audiences you’re a part of that influence which ads you see on Facebook, and adjust which audiences you're a part of. You can also view and adjust your ad preferences here.
Use interest-based advertising controls. If you don’t want Facebook to use information based on your activity on websites or apps off Facebook for the purpose of showing you ads, you can opt out from your settings. Learn more about online interest-based advertising from Facebook. You can also opt out from all participating companies through the Digital Advertising Alliance in the US, the Digital Advertising Alliance of Canada in Canada or the European Digital Advertising Alliance in Europe, or opt out using your mobile device settings.
