Self-serving ads have been on Twitter for a while. So what’s the big deal? Their ad platform is now open to all US users, instead of by invitation only. The ad platform now includes a bit of Twitter-in-house analytics to help advertisers manage their campaigns. Additionally, their reporting system offers extended data on Promoted Tweets to help advertisers maximize their ad dollar, or at least track it better. Far from Google Analytics, the data will still help advertisers compare across channels to analyze where they get the most bank from their buck.
