<p>Twitter is ready to roll out retargeted ads fueled by browser cookies, sources confirm. Twitter could make the announcement as soon as tomorrow, expanding retargeted ads beyond the "experimental" phase that started in July. The secret sauce of Twitter's retargeting is the use of your account as a cross-device identity layer, allowing it to target ads on mobile based on where you've been on the web. Update: Confirmed, Twitter has now announced the program.</p><p>Some details of the announcement are hazy. It's said to be somewhat of a "soft launch" in that all advertisers might not be immediately eligible to buy the ads, and they might not show up to all users. Retargeted Promoted Tweet ads will almost surely become available for purchase, though it's unclear if Promoted Accounts will, too. I haven't heard whether Twitter will be expanding email address retargeting either. Twitter declined to comment on this story.</p><p>[Update: Twitter has confirmed our scoop with the announcement of Tailored Audiences - its name for retargeted ads. Available globally to all advertisers via a slew of adtech startup partners, advertisers will be able to target recent visitors to their websites with retargeted Promoted Tweets and Promoted Accounts. While we nailed most of the details including the launch date and how Tailored Audiences work, rather than selling retargeted ads directly to advertisers as we expected Twitter to do in continuation of the retargeting alpha program, it will sell them through partners Adara, AdRoll, BlueKai, Chango, DataXu, Dstillery, Lotame, Quantcast, ValueClick, and [x+1].]</p><p>Cookie retargeted ads could make sure the ads you see on Twitter are for things you actually want. For example, if I visited the pricing webpage for a Financial Times subscription, it could later retarget me with this promoted tweet, which I'm likely to click as I was already considering buying a subscription.</p><p><a href="http://techcrunch.com/2013/12/04/twitter-retargeted-ads/">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.adweek.com/news/technology/how-twitter-stepped-its-ad-game-154326">Tech: How Twitter Stepped Up Its Ad </a> (Adweek)</p><p><a href="http://www.usatoday.com/story/tech/2013/12/05/twitter-takes-next-steps-in-promoted-tweets-ads/3880001/">Twitter takes next steps in promoted tweets ads</a> (USA TODAY)</p><p><a href="http://www.pcworld.com/article/2069680/twitter-gobbles-up-more-cookies-with-retargeted-ads-says-users-have-privacy-choices.html">Twitter gobbles up more cookies with retargeted ads, says users have privacy ...</a> (PCWorld)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=dKGO7T8cz1UmB1MurdPuwsO32gh6M&ned=us">120 additional articles.</a></p>
