Which one of these is a bad Call To Action?

Get started" is a weak Call To Action (CTA) because it is vague and doesn't clearly communicate the benefit or the next step for the user. While it implies an action, it lacks specificity about what "starting" entails. "Buy it today!" is a strong CTA for a product, clearly indicating the desired action and creating urgency. "Schedule your free call" is excellent for service-based businesses, offering a clear, low-commitment next step with a benefit. "Download the guide now!" is effective for lead generation, providing immediate value in exchange for a click and creating urgency. These options are superior because they are specific, benefit-oriented, and guide the user toward a clear action.
