Call to action buttons are very important for websites and should not be neglected in any case. Getting a visitor do to a certain action translates into a conversion and that’s an important part of any site. Making an effective call to action is not as easy as people might think. It’s not only the color that matters, but also the shape and the message that you apply on it. You want the visitor to do a certain thing, like adding a product to cart, or registering for a service or downloading a file.
Although there are a lot of call to action buttons, I am surprised that not many of them take a modern approach to this issue. However, while researching for this article I’ve seen some sites who pay attention to this little but very important detail. The examples that you have here in this article have each their own style and I hope they will inspire you when working on your next project.
