Have you heard about SponsoredTweets.com? It’s the latest way to advertiser through the Twitter platform with people who have a good Twitter following. You have to pick and choose who you want to Tweet your message and you can track the performance through links. From my initial experience with Sponsored Tweets it has been really great exposure for my campaigns. Also, I’m ready to be one of their Tweeters and make some money by Tweeting other people’s messages. I can approve or deny any requests to Tweet which is really cool. I’m completely stoked with SponsoredTweets…they have done a great job with the platform. It’s pretty easy to use once you get the hang of it. And they a really nice looking affiliate program as well.
