- An impression is a display, not an attentive view nor a distinct person.
- The definition changes by platform: Google Ads counts the display, Meta counts appearance on screen, Search Console counts presence in the results page even without scrolling.
- Impressions divided by reach gives frequency, often more telling than either figure on its own.
Definition
An impression is one display of an ad or a result. It says nothing about the attention paid, nor about the uniqueness of the person reached.
Formula
There is no calculation: the metric is a counter. Two ratios derive from it: CTR, clicks divided by impressions, and frequency, impressions divided by reach. CPM derives from it too.
Worked example
A campaign records 200,000 impressions for 45,000 people reached: frequency is 4.4. With 2,000 clicks, CTR is 1%. If frequency keeps climbing while CTR falls, the audience is tiring: the problem is repetition, not the creative.
Orders of magnitude
The metric has no benchmark value: a hundred thousand impressions mean nothing without the budget, the audience and the objective. What you watch is how it moves against reach and cost.
The most common mistakes
- Confusing impressions and reach. Impressions count displays, reach counts people. One person alone can generate twenty impressions.
- Adding up frequencies across campaigns. Frequency is not additive: two campaigns at a frequency of 3 do not make 6 on a shared audience.
- Reading Search Console impressions as seen displays. A result in tenth position counts an impression even if the visitor never scrolled. On Google Ads, the symmetrical question of coverage is read through impression share.
Where to find the metric
In Google Ads, the Impr. column. In Meta, the Impressions column, to be read with Reach and Frequency. In LinkedIn Ads, the Impressions column, with viral impressions counted separately. In Search Console, the Performance report, Impressions column.
