How do I effectively use a clear call-to-action on Google Ads landing pages?

A clear call-to-action on a Google Ads landing page tells visitors exactly what to do next. It should be easy to find, action-oriented, and placed both at the top and bottom of the page. The button should stand out visually. The wording should be direct, such as “Book a Demo” or “Start Free Trial.” Repeating it naturally throughout the page helps guide decisions.
