Digital marketers love ROAS because it creates a simple number. Spend LKR 100,000 on advertising, attribute LKR 800,000 in revenue to the campaign and report an 8x return on ad spend. On the screen, that looks exceptional.

The problem is that revenue and profit are not the same thing.

Imagine a tour operator sells an LKR 300,000 package. A large part of that money may immediately leave the business through hotels, vehicles, guides, tickets, meals and payment costs. If the operator keeps only a relatively small margin, evaluating advertising against the full LKR 300,000 creates an inflated picture of campaign performance.

Hotels face similar complications. OTA commissions, payment fees, meals, housekeeping, utilities and promotional discounts can change the actual economics of a reservation. A direct booking and an OTA booking with the same room revenue may have completely different profitability.

Cancellations create another distortion. Advertising platforms may attribute a booking when the reservation is created, while the customer later cancels or receives a refund. If the marketing report never reconciles those outcomes, ROAS becomes artificially high.

This is why customer acquisition cost deserves more attention. Instead of asking only how much revenue advertising generated, businesses should understand approximately how much it costs to acquire a paying customer and what contribution that customer creates after variable costs.

Longer-term customer value can change the equation again. Spending LKR 10,000 to acquire a guest may look expensive on the first booking, but the economics become completely different if the same guest returns next year or refers additional customers without requiring another paid campaign.

Different products also deserve different acquisition thresholds. A one-hour activity worth USD 30 cannot usually support the same acquisition cost as a fourteen-day private holiday. Treating every conversion equally makes budget allocation much less intelligent.

This is where proper tracking and financial data need to meet. The marketing team may understand clicks and campaigns while the operations team understands margins and cancellations. Strong decisions require both sides.

ROAS remains useful, but it should be treated as one diagnostic metric rather than the final definition of success. Cost per qualified lead, customer acquisition cost, conversion rate, cancellation rate, average booking value and margin can provide a much more complete picture.

A campaign should not be celebrated because a dashboard shows a large multiplier. It should be celebrated when it creates customers the business can serve profitably.

At Tourithm, we believe tourism marketing becomes much more valuable when reporting moves past advertising-platform numbers and connects with the actual economics of the business.
