These are the costs revealed in the leaked email from Twitter's ad sales department:
- Cost of $2.50 and $4 per follower
- $0.75 to $2.50 for each click, favourite, retweet or reply.
- Commitment to a minimum campaign spend of three months and $15,000
Since Twitter introduced its advertising through its Promoted Tweets we've had questions from marketers about costs and whether the service would become available to advertisers with smaller budgets as is possible through Adwords, Facebook and LinkedIn.
