Label buttons clearly Usability

The label of a button should tell users exactly what happens when they click the button.

Good examples of button labels include Search, Create Account, Cancel, Send Message and Register

The default label Submit does not clearly indicate what happens when the button is clicked, and since it’s the default label triggers very different actions on different sites.
