Try Benefit Buttons instead of just task based ones. Imagine two simple buttons displayed on a page. One button tells you that it will “Save You Money”, while the other one asks you to “Sign Up”. I’d place my bets that the first one might have a higher chance of being acted on, as a sign up on it’s own has no inherent value. Instead, a sign up process takes effort and is often associated with lengthy forms of some sort. The hypothesis set here is that buttons which reinforce a benefit might lead to higher conversions. Alternatively, the benefit can also be placed closely to where the action button is in order to remind people why they are about to take that action. Surely, there is still room for task based actions buttons, but those can be reserved for interface areas that require less convincing and are more recurring in use.
