Impressions, clicks and click-through rate are the three base metrics of digital visibility, and each answers a different question. An impression counts one instance of your content being served to a screen. A click counts one person who acted on it. Click-through rate, or CTR, is clicks divided by impressions, expressed as a percent. Together they show not just how many saw you, but how many cared.

What an Impression Measures
An impression records that content appeared, nothing more. Impressions count exposure, so a high number confirms your reach was wide, not that anyone read, remembered or responded.
The metric is a denominator, not an outcome. Impressions matter as the base against which action is measured, and read as a result on their own they become the textbook vanity metric.
What a Click Measures
A click records a decision. Unlike impressions, a click means a person saw your content and chose to engage, which makes clicks the first genuine signal of interest in the funnel.
Clicks still stop short of value. A click proves attention was won, not that the visit converted, so clicks sit between raw impressions and the outcome that actually pays.
What CTR Reveals
Click-through rate connects the two. CTR divides clicks by impressions, so it measures how compelling your content was to the people who saw it, independent of how many that was.
A rising CTR means relevance improved. Two campaigns with identical impressions can post very different CTRs, and the gap is the clearest read on whether your message matched the audience.
How to Read Them Together
Never judge one metric alone. Impressions without CTR hide whether reach was wasted, and clicks without impressions hide whether the rate was strong or merely lucky on a tiny base.
Use CTR as the diagnostic. When impressions are high but CTR is low, the targeting worked and the message did not; when CTR is high but impressions are low, the message works and distribution is the constraint.
Context decides which number matters. A brand campaign may accept low CTR for wide impressions, while a performance marketing push lives or dies on CTR, so the same three metrics tell opposite stories depending on the goal.
