Evaluate the service as an investment, using your own numbers. Work out what the project costs in full over a set period and how many extra customers it has to bring in to cover that. Then decide how you'll tell whether the website was the cause. "ROI-driven" is a label an agency chooses for itself. What you can check is the evidence behind its past results, what you'll own at the end, and how the outcome will be measured.
