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?
Best Practices for Effective Call to Action Buttons
1. Draw user attention with size
2. Draw user attention with prominent positioning
3. Use whitespace to detach call to actions from other elements
4. Use highly contrasting colors
5. Offer secondary alternative actions
6. Convey a sense of urgency
7. Tell users that taking action is easy
8. Tell users what to expect
