Output: the modelled cost of the same sessions at a reference cost per click, in currency per period.
Returns what the same traffic would cost as paid media, in currency per period. It supports one decision: whether a page or channel earns its keep against paid acquisition.
The calculation is sessions multiplied by a reference cost per click. It is a comparison, not a report of money you spent.
Read the result against the cost of buying the same sessions.
12,000 sessions × $0.70 = $8,400 / month
A high value means the traffic would be expensive to buy. A low value means paid acquisition is the cheaper route. Neither reading says the sessions convert.
