What specific campaign performance metric directly indicates the percentage of users who clicked on an ad after seeing it?

The specific campaign performance metric that directly indicates the percentage of users who clicked on an ad after seeing it is the Click-Through Rate (CTR). CTR is calculated by dividing the number of clicks an ad receives by the number of impressions (times the ad was shown), and then multiplying by 100 to express it as a percentage. A higher CTR generally indicates that the ad is relevant and engaging to the target audience. For example, if an ad receives 1000 impressions and 10 clicks, the CTR would be 1%. Monitoring CTR is crucial for assessing the effectiveness of ad creative, ad copy, and targeting. A low CTR might indicate that the ad is not resonating with the audience or that the targeting is not precise enough. Therefore, CTR is a key metric for optimizing LinkedIn ad campaigns and improving overall performance.
