Call to Action Buttons: Examples and Best Practices

Call to action in web design — and in user experience (UX) in particular — is a term used for elements in a web page that solicit an action from the user. The most popular manifestation of call to action in web interfaces comes in the form of clickable buttons that when clicked, perform an action (e.g. "Buy this now!") or lead to a web page with additional information (e.g. "Learn more…") that asks the user to take action.

How can we create effective call to action buttons that grab the user’s attention and entice them to click? We’ll try to answer this question in this post by sharing some effective design techniques and exploring some examples.

Best Practices for Effective Call to Action Buttons
