Definition
A call to action (CTA) is the explicit instruction — typically a button, link, or imperative sentence — that tells a visitor what to do next: "Get a Quote", "Start Free Trial", "Book a Call".
The CTA is the conversion. Everything before it — copy, design, social proof — exists to earn the click. A weak CTA squanders that work; a strong one cashes it in. The CTA is the single most-tested element in conversion optimisation precisely because small changes have outsized effects.
Good CTAs are specific, action-oriented, and benefit-led. "Submit" is what the form does to the data. "Get my free audit" is what the visitor gets. The first focuses on the system; the second on the user. Conversion-optimisation testing has shown over and over that user-centric CTA wording outperforms system-centric wording by 10–30%.
Origin
Direct-response advertising has used calls to action since mail-order catalogs in the 19th century ("send 25 cents and we'll mail you …"). The phrase entered web design through the email-marketing and conversion-rate-optimisation movements of the early 2000s.
How it works
- Define the action — what should the visitor do?
- Phrase it as a benefit to the visitor, not a system instruction.
- Make it visually unmistakable — high contrast, generous size, isolated from competing elements.
- Place primary CTA above the fold and at the end of every meaningful section.
- Have one primary CTA per screen — secondary CTAs (text links) handle alternative paths.
- Test wording, colour, position; let data settle the disagreements.
When to use it
Use when
- Every page that has a goal — and that's most pages.
- Every email, ad, or asset designed to drive an action.
Skip when
- On purely informational pages with no business goal — but those are rarer than teams assume.
Key metrics
- Click-through rate on the CTA.
- Conversion rate on the goal the CTA leads to.
- Test win rate when CTA wording is varied.
Examples
- The CTA wording change from 'Sign Up' to 'Start Building' lifted clicks by 22%.
- One primary CTA per screen — competing CTAs split attention.
- We tested 7 CTA variants; the winner was 19% above control.
In practice at Makreate
Makreate writes and tests CTAs as part of every landing page and ad — wording, position, contrast, and friction all get measured. On a recent B2B engagement we replaced "Submit" with "Get my free roadmap" on a lead-capture form. Same form, same audience: form-fill rate climbed 31%. CTAs aren't decoration; they're the conversion.
Website Design & Development →Common mistakes
- Stacking competing CTAs. Visitors who can't pick, leave.
- Vague verbs ("Submit", "Learn more", "Click here"). Specificity wins.
- Insufficient contrast. CTAs that visually melt into the page lose clicks silently.
- Inconsistent CTA wording across surfaces. The same offer should use the same words across ad, page, and email.
- No test. The first CTA you write is rarely the best one.
Frequently asked
How many CTAs per page?
One primary CTA repeated multiple times. Secondary CTAs (text links) for the alternative paths a visitor might want.
Best colour for a CTA?
The one with the highest contrast against everything else on the page. There's no universal "best colour" — there's the colour that pops on your specific design.
Verb in the CTA?
Yes, almost always. Imperative verbs ("Get", "Start", "Book") outperform noun phrases ("Free Trial").
