A call-to-action, most commonly referred to as a CTA, is a technique used in content marketing ads and campaigns to motivate or entice viewers to take action. It usually instructs viewers to make an immediate response, such as “call now “or “visit us today.” A CTA may often come in the form of a reason that a viewer should act immediately, such as “limited stock” or “offer expiring soon.” Marketers also use CTAs in the form of special deals within a specified time frame, such as “order in the next hour to receive a free gift.” The goal of including a CTA is to compel a viewer to purchase or act promptly rather than delaying.
