Which option correctly describes CTR?

• A. Clicks to impressions.
• B. Impressions to clicks.
• C. Clicks to conversions.
• D. Conversions to impressions.

Answer: (A)

CTR shows how often people who see an ad actually click it. It’s the number of clicks divided by the number of impressions, usually shown as a percentage. That means the idea described is clicks relative to impressions—the viewer sees the ad (an impression) and a portion of those views result in a click. The other descriptions don’t match CTR. Impressions to clicks would be the inverse ratio (how many impressions per click), which is not CTR. Clicks to conversions describes the conversion rate (how many clicks lead to a desired action), which is a different metric. Conversions to impressions describes conversions per impression, another distinct metric.
