Getting a good click through rate means people are interested enough to click, but conversion is what happens after they land on your page. If people click but do not take action, the problem is often the page itself. The message in the ad must match what they see next, or they may feel confused. Also, slow loading pages or unclear offers can make people leave quickly. It is important to guide visitors clearly on what to do next. What do you think matters more, the ad or the landing page?
