What is a performance marketing agency?

A performance marketing agency is an agency that runs paid social and PPC as an acquisition system built around acquisition economics, with creative testing, tracking and conversion optimisation working together, then improved on evidence rather than opinion.

It builds the whole loop: strategy, targeting, creative, landing experience, tracking and reporting. Then it runs it as a cycle of testing, reading and adjusting, so spend goes behind what works and away from what doesn't.

The defining trait is accountability to a measurable outcome. If the work isn't tied to a cost per acquisition or a return on ad spend, it isn't performance marketing, it's just media buying.

A general agency may run paid media as one of many channels. A performance marketing agency makes acquisition economics the centre. The creative is built to convert, the tracking is built to attribute, and the budget is governed by what the numbers say, not by a schedule.

When paid spend is real money and the question 'did it work?' needs a defensible answer. A performance marketing agency earns its fee when the cost of being wrong about spend is higher than the cost of getting it right.
