Advertising on Twitter? There are a number of factors to consider: use of hashtags, use of keywords, target audience and locations.

Our research shows that promoted trends lead to higher number of tweets, while promoted tweets lead to higher user engagement, which may be the ultimate measure of success. For a use-case study, see:
