A few years ago, I learned that if I told people to "CLICK HERE", many of them would.
Nowadays, "click here" is considered lame or spammy, but it still works.
This short article covers some other ways to use language to get action from a visitor.
http://www.dustincurtis.com/you_should_follow_me_on_twitter.htmlThe result of switching to a command is pretty remarkable; the clickthrough rate jumped by 55% to 7.31%.
As a side note, I also found that using a lower case “t” for Twitter in this phrase and the ones below (but, for some reason, not the first one) led to a slightly higher rate of clicks (up to 6% more). I can’t really think of any rational reason for this except that a lowercase “t” makes the phrase look more like an uninterrupted sentence.
