Call to Action (CTA)
A call to action (CTA) is a prompt, usually a button or link, that tells a visitor exactly what step to take next toward a desired outcome.
In depth
A CTA works as the bridge between content and conversion: after the page builds interest or delivers value, the CTA names the next action and makes it easy to take. It typically pairs an action verb with a clear outcome and stands out visually so it is impossible to miss. Good CTAs reduce decision friction by removing ambiguity, signaling low risk, and arriving at the moment the visitor is most motivated rather than too early or too late.
A frequent pitfall is vague or self-centered wording such as "Submit" or "Continue," which tells the visitor nothing about the value waiting on the other side. Effective CTAs are framed around the visitor's benefit and matched to the funnel stage, so an early CTA invites a low-commitment first step while a later one collects the payoff. In a quiz funnel, the primary CTA starts the assessment ("Find your score") and a second CTA on the result page drives the conversion that captures the qualified lead.

Frequently asked questions
What is the difference between a CTA and CTA optimization?
A CTA is the prompt itself, such as a button telling visitors to start a quiz. CTA optimization is the ongoing process of testing and improving that prompt's copy, design, and placement. In short, the CTA is the element, and optimization is how you make it perform better.
Where should I place the main CTA?
Place it where motivation peaks, which usually means right after you have communicated the value, not buried at the bottom. On long pages, repeat the primary CTA at logical decision points. On a quiz result page, the conversion CTA belongs next to the personalized outcome the visitor just earned.
Can a page have a CTA without a button?
Yes, a CTA can be a text link, an inline prompt, or even a voice or chat cue, though a clearly styled button is the most common and visible form. What matters is that the next action is obvious and easy to take. The format should match the context and the device.
