Reach is modeled as impressions ÷ frequency, capped at your audience size — a planning estimate, not a guarantee.

Real platforms de-duplicate reach differently and apply frequency caps that vary by channel.

An effective frequency of 3–7 is ideal for most awareness goals.

Reach, Frequency & Impressions

Three metrics that define every awareness campaign — and how they relate.

Impressions

Every single time your ad renders on a screen — including multiple views by the same person. Bought via CPM.

Reach

The count of unique individuals who saw your ad at least once. This is the audience you actually touched.

Frequency

The average number of times each reached person saw your ad. Frequency = Impressions ÷ Reach.

Effective Frequency

The 3–7 exposure window where memory and response peak. Too few and it fades; too many and it fatigues.

Audience Coverage

Reach as a percentage of your total addressable market. 30–50% coverage at frequency 3+ drives brand lift.

Cost Per Reach

Budget ÷ unique reach — the true price of getting your message in front of one new person.
