It appears that Promoted Tweets have started appearing in TweetDeck. In September, Twitter announced it was bringing “promoted tweets”  to third-party apps. However, only Hootsuite publicly confirmed plans to include promoted tweets within the streams of tweets in its app. Twitter.com began displaying promoted tweets last year.

Today, Promoted Tweets began appearing in TweetDeck users’ streams. These tweets “stick” at the top of columns and are marked with “Promoted by [Twitter Name]” under the tweet. It is unknown how long promoted tweets remain “stickied” at the top of Tweetdeck columns, or if these options can be varied by the advertising. There is also no option in Tweetdeck to turn off Promoted Tweets, unlike in Hootsuite, where you can upgrade, at a cost, to avoid Promoted Tweets.

Previously, advertisements on Twitter have only appeared on Twitter.com, and users who accessed Twitter through apps like TweetDeck didn’t see Promoted Tweets. Twitter charges for these tweets on a cost: advertisers pay whenever someone clicks through to a link, retweets the ad, or follows the advertiser. Now that Tweetdeck is showing promoted tweets, it will be interesting to see if and when Tweetdeck allows users to pay to opt-out out of Promoted Tweets.

Have you started seeing Promoted Tweets in TweetDeck? Would you pay to opt-out of advertising on TweetDeck?
