Beyond the views: measure what matters. A clear objective and a realistic plan make the work easier to evaluate.
Start with the objective
Discovery campaigns may track relevant reach and visits. A promotion may track enquiries, redemptions or documented purchases.
Prepare measurement before launch
An offer code or a simple registration record may help. Collect only necessary data and explain its intended use.
Keep the distinctions clear
An enquiry is not an order; an order is not necessarily paid. Seasonality, price changes and other campaigns can also explain a change in sales.
