What is a call to action (CTA)?
Also called: CTA, CTA button, call-to-action button
Definition
A call to action (CTA) is the prompt, usually a button or link, that tells a visitor what to do next, such as "Start free trial", "Launch your product" or "Join the waitlist".
Call to action (CTA), explained
Every page should have a job, and the CTA is how the visitor does it. The best CTAs are specific about what happens when you click. "Start free trial" beats "Get started", which beats "Submit". "Generate my robots.txt" beats "Go". Specific wording reduces the uncertainty that makes people hesitate.
Say what it costs and what happens next when it matters: "Start free, no credit card", "Book a 20-minute demo", "Join the waitlist, we'll email when it's ready". Hidden commitments make people abandon forms halfway through.
Placement: put the main CTA in the first screen, then repeat it after the sections that answer objections, and at the end of the page. On long pages, a visitor who's convinced halfway down shouldn't have to scroll back up. On mobile, make buttons large enough to tap easily.
One primary action per page. Secondary actions ("See pricing", "Watch demo") can be present but visually quieter. Five equal buttons make every choice harder.
Honesty matters for CTAs more than for most copy. If a product isn't live, the CTA should say "Join the waitlist" or "Apply", not "Buy now". Our own paid offers collect a waitlist or application until payments are live, and the buttons say so. Misleading CTAs may lift clicks briefly, but they create angry sign-ups and support tickets.
Content pages need CTAs too. A glossary entry or guide should end with a relevant next step, like a tool to try or a deeper guide, not a hard sell unrelated to the topic.
Why it matters for founders
Visitors who are ready to act need an obvious, honest next step. Small wording and placement changes to CTAs are among the cheapest conversion improvements available.
Example
A founder changes "Get started" to "Create your first report free" and adds "No credit card" underneath. Sign-ups from the same traffic go up, and fewer people abandon the sign-up form.
Common mistakes
- Vague labels like "Submit" or "Learn more" everywhere.
- Several competing primary buttons on one page.
- CTAs that promise something the product can't do yet.
