This lesson covers the key metrics you need to monitor in Ads Manager — Click-Through Rate (CTR, how many people click after seeing your ad), Cost Per Click (CPC), Cost Per Result (CPR, cost per lead/purchase/etc.), and Return on Ad Spend (ROAS). It covers what “good” benchmarks generally look like for each metric depending on your industry and objective, and how to identify which metric is signaling a problem — for example, low CTR often points to a creative issue, while high CPC with good CTR might point to audience or bidding issues.
