Also known as: Call to Action

Short answer

A CTA (call to action) is the element that invites a person to take the next step: a button such as "Get a quote", a link such as "See plans" or a line at the end of an ad. It turns interest into action. A good CTA says exactly what happens when someone clicks.

Hypothetical example

A solar energy company had a button that said "Submit" at the end of its form. It changed it to "Get my savings estimate", making clear what the person receives.

Same form, same fields. What changed was the expectation: whoever clicks knows they will get something useful, not that they are joining a sales list.

Weak CTAs and strong CTAs

A weak CTA describes the mechanics of the click: submit, click here, learn more. A strong CTA describes what the person gets in return: the estimate, the quote, the access. The difference looks small and changes the decision, because it answers the question visitors ask before clicking: what do I get?

From weak to strong
	Weak	Strong
Form	Submit	Get my estimate
Store	Buy	Buy with free shipping
Software	Sign up	Try 14 days, no card
Service	Learn more	See prices and timelines

Where to place the CTA

At the top, visible without scrolling, for people who arrived already decided.
After the arguments, for people who needed to read first.
At the end of the page, for people who read everything.
Always the same one, repeated. Several calls to different actions on one page split attention.

How to write a good CTA

Start with a verb and state the result: "Book my assessment", "Download the guide".
Remove risk up front: "no commitment", "cancel anytime", when it is true.
Use the first person when it fits: "Send me my proposal" often feels closer than "Request your proposal".
Make the button look like a button: contrast with the background and a comfortable size for a thumb on mobile.
Do not promise what will not happen. If the click opens a long form, say so.

CTAs exist beyond the website

Every ad has a CTA, sometimes in a button set by the platform and sometimes in the copy itself. Emails have CTAs, videos have CTAs, posts have CTAs. The rule is the same everywhere: one clear action per piece, phrased so people know what comes next.

What does CTA stand for?

How many CTAs should a page have?
