Twitter has announced a new always-on service that automatically promotes tweets called Promotion Mode.

The social platform launched the feature, priced at $99 a month for those who want to have an automated, advertising solution for their brands and products. According to Twitter, smaller brands, with up to 2,000 followers will see the most value.

The service automatically selects tweets to be promoted, which will become ‘promoted’ tweets. For these (probably) smaller brands, all they have to do is post as they normally do to and this new feature boosts the message to their target audience. When the feature is enabled, the first ten Tweets that pass their quality filter will be placed into a campaign that targets that audience. Retweets, quote tweets and replies are not included in this feature.

The ‘promote mode’ will also promote the account running the campaign as a user to follow users in its target audience. Twitter said that not every tweet that is added to your Promoted Tweet campaign will serve an impression, and how well that tweet is promoted depends on its individual performance. They’ve anticipated that through this feature, accounts can reach an average 30,000 more people and add around 30 followers a month.

Users utilizing ‘promote mode’ can access data for their tweets, reach, and profile visits through a specialized dashboard. Twitter said it plans to announce a tier based system for accounts with larger followings at a higher price “in the future.”
