What is a Call to Action (CTA)?

A Call to Action (CTA) is a prompt—usually a button, link, or short message—that tells users what to do next. It guides visitors toward a specific action such as purchasing, signing up, downloading, or contacting a business.

An effective CTA converts passive visitors into engaged leads or paying customers.

• Communicate value or benefit clearly
