Report: Longer tweets elicit more clicks

Zarrella found that as the length of tweets grew, so did the number of clicks for a link in the tweet. Once the tweet reached 130 characters—the maximum number of characters for a tweet is 140 characters—the number of click-throughs fell.

“So it seems as though Twitter users are more likely to click on links in tweets if they’re accompanied by something else, such as a description of the link,” Zarrella explained in a blog post.
