Marketing measurement starts with a clear action. Decide whether the campaign should produce calls, WhatsApp enquiries, bookings, store visits, orders, or repeat purchases. Then record the source and outcome.
Use simple labels such as Google, WhatsApp, Instagram, referral, flyer, or campaign name. Record how many people asked, how many were suitable, how many bought, total revenue, direct cost, and time spent following up. For a service business, include booked appointments and completed jobs rather than enquiries alone.
Review the numbers weekly or monthly. A channel with fewer enquiries may produce better customers. A high number of messages may reveal that the offer is unclear or the price is missing. Likes and views can help diagnose reach, but they are not the business result. Measure the next step after attention.
