You’re creating a video ad for a salon and your goal is to drive client bookings through the salon’s website. Which of the following call to actions (CTAs) should you use in the ad?

Book now" is the most effective CTA because it directly aligns with the campaign's goal of driving client bookings through the website. It clearly communicates the desired action to the viewer. "Call now" would be suitable if the goal was phone bookings, but the question specifies website bookings. "Learn more" is too generic and doesn't explicitly prompt a booking, while "Take a look" is even less action-oriented and unlikely to convert viewers into clients.
