Market Capacity
The total addressable size/capacity of a given market or GEO.
Market Capacity is the total addressable size of a given market or GEO — how much traffic and how many convertible users realistically exist before you saturate demand and returns diminish. It sets the ceiling on how far a profitable campaign can scale within one geo before frequency climbs, CR drops and cost per result rises past the point of profit.
Buyers weigh capacity when deciding whether to pour budget into scaling a winner or to expand into new geos instead. Small Tier-1 niches saturate fast: you scale, audiences overlap, and the same offer that printed money last week stops converting. Misjudging capacity leads to overspending into a tapped-out market — read rising frequency and falling CR as the signal you've hit the ceiling.
In buyer speech
“We've maxed the market capacity in this GEO — frequency's climbing and CR is dropping, so let's open a second geo instead of scaling here.”
