You're working on a Google Search ad that's not performing as expected. You specifically want more users to click on the ad. What action might improve the click-through rate on your ad?

Changing the call-to-action (CTA) message directly impacts user engagement and can significantly improve click-through rate (CTR). A compelling and relevant CTA encourages users to click by clearly stating what action they should take and what benefit they will receive. Increasing website trustworthiness and modifying the landing page load speed are important for overall ad quality and user experience after the click, but they don't directly influence the decision to click on the ad itself. Reducing the bid rate would likely decrease ad visibility and potentially lower clicks, rather than increase them.
