I think that this quite recent article (June 2014) about the "Sign Up" buttonarticle about the “Sign Up” button is interesting.
The, the author changed the “Sign Up” button to “Try it Free”changed the “Sign Up” button to “Try it Free” and clicks increased by 212%.
His thesis is that the standard "Sign Up"“Sign Up” buttons don'tdon’t work because "“they ask for blind commitment"” and "“do not offer any value"”.
Visitors also "see“see common elements repeated on many sites"sites” and "they“they begin unconsciously ignoring those elements (aka “habituation”)"”.
Therefore heHe suggests to:
- Tie it to your product. If you have a SaaS for trading bitcoins: “Start Trading Bitcoins.” If you have a marketplace for artists artists: “Start“Start Selling Art.” This helps prevent the button from being overlooked being overlooked.
- Give, don’t take. “Get Access” and “Sign Up” both lead to thethe same thing, but one makes the visitor feel they’re getting
something something, while the other doesn’t.- CompellCompel people to act. Use action verbsverbs such as get, start, and try.
Of course there are many variables to consider (what kind of website is yours? Changing the label of the button increases clicks, but what about new subscriptions? etc.) but it may be worth having a look at it.
