How to write a call-to-action (the formula)

Writing a great call-to-action isn’t art — it’s a formula. Once you know it, you can fix any weak button in seconds.

The formula

Action verb + value + specificity

• Action verb: start with what they’ll do — Get, Start, Claim, Add, Grab. Not “Submit.”
• Value: name the benefit or remove the risk — free, today, save, no card needed.
• Specificity: be concrete — “Get my free checklist” beats “Sign up.”

Keep it to 2–4 words. Long CTAs lose people; one-word CTAs (“Submit”) say nothing.

Add the shopper’s voice

First-person framing converts: “Start my free trial” tends to beat “Start your free trial.” It reads as the visitor talking, which makes clicking feel like their decision.

Common mistakes

• Generic filler — “Click here,” “Continue,” “Learn more.” Vague and robotic.
• No benefit — “Sign up” tells me the action but not why.
• Competing buttons — if your secondary CTA looks as loud as your primary, you’ve split attention.
• Hiding it — the main CTA should be the most prominent element, above the fold, with room around it.

A quick before/after

❌ “Submit” ✅ “Get my free quote”

Same button, very different click-through.
