About tailored ads
We work with ad partners to bring you more useful and interesting advertising content. We may do this based on information that our ad partners share with us. We hope that this increases the usefulness of Twitter Ads for you.
Here’s one way it would work. Let’s say a flower shop wants to advertise a Valentine’s Day special on Twitter. They’d prefer to show their ad to floral enthusiasts who subscribe to their newsletter. To get the special offer to those people, who are also on Twitter, the shop may share with us an unreadable scramble (called a hash) of emails from their mailing list. We can then match that to a hash of emails that our users have associated with their accounts in order to show them a Promoted Tweet for the Valentine’s Day deal on Twitter.
Another way this works is when a person visits the flower shop’s website. In that case, the shop may share with us browser-related information (a browser cookie ID) that we can then match to an account that may receive the Valentine’s Day offer.
It’s up to you
If you do not want Twitter to tailor ads based on our ad partners’ information, you can uncheck the box next to “Promoted content” in your account settings at any time:
When you uncheck this box, Twitter will not match your account to information shared by ad partners for tailoring ads. This means we would not collect browser-related information from our ad partners or match their email hash for tailoring ads. This is the only place you’ll need to disable this feature on Twitter.
In addition, Twitter supports Do Not Track (DNT). When you have DNT enabled in your browser, Twitter would not receive browser-related information from our ad partners for tailoring ads. Get more information on DNT, including how to enable it in your browser.
