When analyzing a landing page's performance, which metric MOST directly indicates whether the page effectively converts visitors after they click an ad?

When analyzing a landing page's performance, the Conversion Rate is the metric that MOST directly indicates whether the page effectively converts visitors after they click an ad. Conversion rate is calculated as the percentage of visitors to a landing page who complete a desired action, such as making a purchase, filling out a form, or subscribing to a newsletter. For example, if 100 people click on an ad and land on your page, and 5 of them make a purchase, the conversion rate is 5%. A higher conversion rate indicates that the landing page is effectively persuading visitors to take the desired action, while a low conversion rate suggests that there are issues with the page's design, content, or user experience that are preventing visitors from converting. While metrics like bounce rate and time on page are important, they are indirect indicators. Conversion rate directly measures the percentage of visitors who complete the desired action, making it the most direct indicator of a landing page's effectiveness.
