I need your help! I'm totally lost. I'm running several campaigns and it seems like they're getting good traffic. How do you determine which is performing better than another? Is there a certain metric I should focus on? I'd recommend focusing on click-through rate. The click-through rate metric is best at helping digital marketers know the relevance or effectiveness of their ad. No worries. We all get lost sometimes. You should continue to focus on impressions. Traffic is the most important metric for PPC. Definitely clicks. You want clicks to be higher than impressions eventually. This means that people are highly interested in your ad and promoted product
