CTA stands for call to action. It's a marketing term for the next step or action that a marketer wants a consumer to take.
In simpler terms, a CTA is a prompt or instruction to encourage a specific action. It's often used in marketing materials, such as websites, emails, and social media posts.
Effective CTAs are usually clear and concise. They contain strong action verbs (e.g. "Buy now," "Sign up") as well as a sense of urgency.
