What is a Call to Action (CTA)? Guide & Examples

The prompt that tells visitors exactly what to do next.

A call to action (CTA) is a prompt — usually a button or link — that tells visitors what to do next, such as "Add to cart," "Get 10% off," or "Subscribe."

CTA examples in ecommerce

  • Add to Cart / Buy Now — the primary purchase action.
  • Get 10% Off — an incentive-driven popup CTA.
  • Subscribe — for email and SMS capture.
  • Claim Offer — for time-limited deals.

What makes a good CTA?

  • Clear, action-oriented text — say exactly what happens next.
  • Contrasting colour — the button should stand out.
  • Strong placement — visible without hunting.
  • A sense of value or urgency — "Get my discount" beats "Submit."

Why popup CTAs convert better

A CTA inside a popup has the visitor's full attention — there are no competing links or distractions. Combined with a clear incentive, that focus is why discount popups and email popups convert so well.
