Call-to-Action (CTA)

Definition
A call to action is the short line of copy or button that tells someone exactly what to do next, pairing a clear verb with a promised benefit.

Why it matters

Interested readers rarely act without being told what to do. A vague prompt lets that interest fade, and a page with plenty of traffic can underperform for this reason alone.

The call to action is also where the page's job is stated. A page with five buttons asks the reader to choose, and a reader who has to choose often leaves. One clear next step is easier to follow, and easier to measure.

It is one of the cheapest changes on a website, too. Rewriting a button takes minutes, needs no developer for most sites and can be tested by comparing results before and after. A change to the headline or the offer is harder to undo. A change to a button label is not.

And it protects the budget spent bringing visitors in. Paying for traffic, a campaign or a conference lead and then giving them an unclear next step wastes what was spent to reach them.

How to apply it

  • Start with a verb and name the outcome: "Get the pricing guide" works better than "Click here".
  • Offer one primary action per section. Several competing buttons split attention.
  • Match the ask to how ready the visitor is. A cold visitor may not be ready for "Buy now", but may take a guide or a short demo.
  • Reduce perceived risk where it is true, for example "no card needed".
  • Place it right after the proof that justifies it, and repeat it at the end of the page.
  • Test wording one change at a time, so the result can be traced to a cause.

What it is

A call to action is the specific instruction at the point where a reader decides whether to move forward. It is usually a button, but it can be a link, a banner or the closing line of an email. A strong one has a verb, a clear outcome and, where it helps, a hint of how little effort or risk is involved.

Compare two buttons on a pricing page. "Submit" says nothing about what happens next. "Book a 20-minute fit call" names the action, the format and the time it takes.

Common mistakes

  • Generic labels such as "Submit" or "Learn more".
  • Asking for too much too soon, like a full form before any value has been shown.
  • A call to action that does not match the promise of the advert or email that brought the visitor.
Worked example

Suppose a consultancy's guide page ends with a button reading 'Submit'. Of all visitors to the page, 1.2 per cent press it. The team builds a variant on a landing page in Unbounce, changing only the button to 'Get the pricing guide' and adding 'No card needed' underneath.

Over three weeks with the same traffic, conversion rises to 2.1 per cent. Nothing else on the variant changed, so the wording is the likely cause. A later test that changes the headline runs separately, so its effect can be measured on its own rather than blended into the first result.
