When running Facebook ads, it is important to understand the purpose of your campaign to decide whether traffic or conversions is a better metric. Traffic is ideal if your goal is to increase the number of visitors to your website or landing page. It helps you gauge interest and reach. However, conversions are the better metric if your goal is to drive specific actions like purchases, sign-ups, or form submissions. Conversions give you a clearer picture of your return on investment (ROI) and the effectiveness of your ad in achieving your business goals.
