A call to action is the sentence — usually inside a button — where you stop describing and start asking. Everything above it argues; the CTA collects. If the rest of the page did its job, the CTA is the smallest bit of copy on the screen and the most important.
The three jobs of a CTA
Any button copy that converts is doing three things at once:
- Names the action. The reader knows exactly what happens on click.
- Names the outcome. The reader knows what they get in return.
- Lowers the perceived cost. Time, effort, risk, or commitment feels small.
“Submit” does one of these. “Get my free proposal” does all three in four words: names the action (get), names the outcome (proposal), lowers the cost (free, my — already yours, no obligation implied).
Verb first, always
A CTA should start with a verb the reader performs, not the verb the company performs. Not “Learn more” — that’s what you want them to do. Try “See the pricing,” “Book my strategy call,” “Start my free month.” The reader is the subject; the outcome is the object.
Verbs that pull
- Get / Grab / Claim — when a specific thing is delivered.
- Start / Begin — when the value is immediate and ongoing.
- Book / Schedule — when a human interaction is the next step.
- See / Show me — when the ask is low-commitment browsing.
- Send / Reply — for email or DM-based conversion.
Verbs to retire
“Submit,” “Learn more,” “Click here,” “Continue” — these describe UI plumbing, not outcomes. If the button copy would also make sense on a bank’s login page, it’s not selling anything.
The first-person swap
Try rewriting your CTA from the reader’s point of view. “Get your free audit” → “Get my free audit.” It reads as a small internal commitment the reader makes on the reader’s behalf, not a marketer’s command. Test it on your top landing page for a week. It usually wins.
The microcopy under the button
The 8–12 words directly beneath the button are the second most valuable text on the page. Use them to remove the last silent objection:
- “No credit card. Cancel any time.”
- “Takes about 90 seconds.”
- “We’ll reply within one business day.”
You’re not decorating the button. You’re resolving whatever the reader was about to hesitate on before they clicked.
Where the CTA belongs
A common mistake: hiding the CTA at the bottom of a long page and hoping. On a short page, one primary CTA above the fold is enough. On a long page, the same CTA repeats after every major argument. A reader who’s convinced at section three shouldn’t have to scroll to section nine to act.
Rule of thumb: after every major promise or proof point, there should be an obvious next step within one screen’s scroll. Same button copy, same destination — not a buffet of choices.
One page, one primary action
Every additional CTA cuts the conversion rate of the main one. If your landing page has “Start free trial” and “Talk to sales” and “Download the whitepaper” all fighting for attention, none of them will do their job. Pick the one action worth the traffic. Make everything else a link, not a button.
A good CTA doesn’t ask harder. It shows up at the exact moment the reader has already decided, and gives them one obvious way through.
A ten-minute audit
- Write out your current CTA. Does it start with a verb the reader performs?
- Does it name the outcome, not the action name of a form?
- Rewrite it in first person. Read both aloud. Which one sounds like something a real customer would think?
- Add one line of microcopy that resolves the biggest remaining objection.
- Ship it. Check the click-through in two weeks.
