A Call to Action (CTA) is a prompt on a webpage or interface that tells the user to take some specific action. It’s usually presented as a prominent button or link with imperative language. Common examples of CTAs are buttons like “Sign Up Now,” “Buy Now,” “Learn More,” or “Download the App.” In UX and marketing, CTAs are critical because they guide users toward the desired interactions and business goals (like making a purchase or registering for a service). A good CTA is clearly visible (often using a distinct color or size), concise in wording, and conveys a benefit or action. For example, instead of a generic “Submit,” a CTA on a newsletter form might say “Subscribe for Updates” which reminds the user of the value they get. CTAs should also appear at the right moment in the user journey — for instance, after providing information about a product, a “Get Started” CTA encourages the next step. In summary, CTAs are the elements that drive user action, and effective CTA design is key to both user experience and achieving product objectives.
