Engagement metrics are essential to evaluate ad engagement. Metrics like Click-Through Rate (CTR) measure how often people click on the ad after seeing it. A high CTR indicates strong ad relevance and appeal. Conversely, a low CTR might suggest the need for better targeting or more compelling creative.

Ad placement and viewability are crucial factors influencing ad engagement. Ads placed in prominent positions on a webpage or app are more likely to be seen and engaged with. Ad viewability ensures that the ad is actually seen by users, which is fundamental for any engagement to occur.

Cost metrics like Cost Per Click (CPC) and Cost Per Mille (CPM) are closely related to ad engagement. CPC measures the cost of each click, while CPM measures the cost per thousand impressions. Both metrics help marketers understand the financial efficiency of their campaigns in driving engagement.

Higher ad engagement often leads to improved conversion rates. When users engage with an ad, they are more likely to take the desired action, such as making a purchase or signing up for a newsletter. Monitoring engagement helps in predicting and enhancing conversion outcomes.

Ad reach and bounce rate are also significant in the context of ad engagement. Ad reach refers to the number of unique users who see the ad, while bounce rate measures the percentage of users who leave a webpage without interacting. A low bounce rate combined with high engagement indicates effective ad targeting and content.
