Tweets With Exclamation Points Get More Retweets!
Because these things actually matter and because there's a guy who love to dig into this stuff, we now know that tweets that include exclamation points get more retweets. However, thanks to Dan Zarrella's examination of 2 million link-containing tweets sent by accounts with at least 1,000 followers, tweets with exclamation points get fewer clicks.
Why is this data important when it's usually all about the click? Because sometimes it isn't. Sometimes all a brand wants to do is make it known something relevant to the brand and of interest to consumers is interesting. JCPenney hyping a sale. Southwest touting discount flights. Or CNN just trying to get a breaking story widely disseminated.
