You're making a video ad for a travel company with the goal of driving bookings on their website. Which of the following call-to-actions (CTAs) should you use in the ad?

For a video ad with an action-oriented goal like driving website bookings, you should use Book now because it is a specific, high-intent call-to-action (CTA) that aligns perfectly with the desired bottom-of-funnel conversion. While "Learn more" or "Check us out" are better suited for awareness or consideration phases, "Book now" removes ambiguity for the viewer, clearly directing them to complete the purchase and significantly increasing the likelihood of a direct conversion from the ad.
