When you create a website, you have a goal with it. You want to inform, to convince or to activate your visitors. Most of the time you don’t want for your visitors to only read or watch; you want them to do something. You want them to subscribe for your newsletter, to buy your product or to contact you for example. Make sure your visitors can easily find the buttons that will bring them to that action you want achieve. Make sure it’s a simple button that is well noticable and let the text tell the action as a verb.
