A Call to Action (CTA) is the specific instruction you give someone to take the next step—like "Start Free Trial," "Book a Demo," or "Download Guide." It's the bridge between interest and action. Good CTAs are clear, specific, and create urgency. Bad CTAs are vague ("Learn More") or create friction ("Request Information").
Use CTAs everywhere you want user action: landing pages, emails, blog posts, pricing pages, signup flows. Every page should have one primary CTA (what you most want them to do) and optionally secondary CTAs (alternatives). The key is making the desired action obvious and low-friction.
