Using the word “click” on your links takes the user’s attention away from your interface and on to their mouse. Users know what a link is and how to use a mouse. It’s unnecessary to call attention to the mechanics when clicking a link. Doing so diminishes their experience of your interface because it momentarily takes their focus away from it. Instead of focusing on the interface and its content, “click here” diverts their attention to the user and their mouse. Not to mention, you can also make them feel dumb by suggesting that they don’t know what a link is or how to use a mouse.
