We use tailored ads on Twitter
Twitter works with ads partners to bring 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.
