The Promoted Tweets you’re used to seeing in searches and on the Twitter.com sidebar will soon show up in your Twitter stream.

As reported by TechCrunch.com, the initial rollout of this new advertising service aims to make Promoted Tweets feel like an organic part of Twitter streams (see the example below):

To be clear, the sponsored Tweets will only appear in your timeline if you already follow the account that has paid for the spot. If that’s the case, a single Promoted Tweet will appear at (or near) the top of your main timeline when you log in to twitter.com for the first time in any given day. As you get new Tweets, these Promoted Tweets will be pushed down just like regular Tweets. But if you refresh the page, the ad will appear at the top of the timeline again, is our understanding.

These ads will also be clearly marked as “Promoted” with an orange arrow icon below the tweet (this is the way Promoted Tweets and Trends are currently shown on the sidebar or in search). And it will say the full company name of the company that is doing the promotion (just in case their Twitter handle isn’t perfectly clear). These Tweets can also be dismissed from your timeline with one click.”

Neither the Tech Crunch article nor Twitter’s blog post on the announcement indicates if this new element will affect the cost of Promoted Tweets. According to ClickZ, Twitter currently suggests a $15,000 minimum spend over a three month period for its Promoted Tweets service.
