Which metric directly reflects the percentage of users who click on your ad after seeing it?

The Click-Through Rate (CTR) is the metric that directly reflects the percentage of users who click on your ad after seeing it. CTR is calculated by dividing the number of clicks your ad receives by the number of times your ad is shown (impressions), expressed as a percentage. For example, if your ad is shown 1000 times and receives 10 clicks, your CTR is 1%. A higher CTR indicates that your ad is relevant and appealing to your target audience, while a lower CTR suggests that your ad copy, targeting, or bidding strategy needs improvement. CTR is a key indicator of ad performance and a crucial factor in determining your ad's Quality Score.
