Promoted Trends on Twitter continue to charge more and more money, and according to a Report by AllThingsD they now charge $200,000 a day. Clocking in at more than twice the original price of $80,000 a day in 2010, Twitter clearly understands that it has a market for the Trends, which were used by both Obama and Romney in the past election, as well as Coke, Disney, and Hyundai in the past year. Purchased hashtags are placed at the top of the trending topics list, and users who click the hashtag see a tweet from the company who purchased it. Other options beyond the Promoted Trend include promoted Tweets and Accounts, which have also proven effective as marketing strategies, but according to Twitter’s data Promoted Trends have a much higher degree of engagement than any other form of advertisement on the site. If, and it’s a big if given the hefty pricetag, Twitter can sell this advertising slot every day, they could generate up to $70 million in revenue just through this method alone. It hasn’t happened yet, but it could in the very near future as social media marketing continues to thrive.
