About tailored ads
We work with ads partners to bring you more useful and interesting advertising content. For example, we may do this based on information that 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 hashed 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 information 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 match your account to information shared by ad partners to tailor ads for you, 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 to tailor ads for you. This means we would not match your account to information shared by ad partners, including browser-related information, mobile device identifiers, and email hashes, to tailor ads for you. This is the only place you’ll need to disable this feature on Twitter.
Twitter also supports Do Not Track (DNT). When you have DNT enabled in your browser, Twitter does not match your account to browser-related information to tailor ads for you. Get more information on DNT here.
On your mobile device, you may also have a “Limit Ad Tracking” setting (on iOS devices) or a setting to “Opt out of Interest-Based Ads” (on Android). If you enable these settings, Twitter will not tailor ads for you by matching your device to app information from ad partners.
In addition, Twitter works with its affiliate TellApart and third-party advertising partners, including Google, to market our services on our behalf and serve ads on behalf of Twitter customers, including through the delivery of interest-based ads. You can learn more about opting out of receiving interest-based ads at www.aboutads.info/choices and www.networkadvertising.org/choices and from TellApart’s FAQs. You can also opt out of Google Analytics by installing Google’s opt-out browser add-on, and out of interest-based Google ads using Google’s Ads Settings.
