Across 120 campaigns, spend beats channel for sales
Across 120 ad campaigns, one number explained almost everything: how much was spent. Ad spend alone accounts for 95% of the difference in sales between campaigns.
Every RM1 spent on ads returned about RM3.21 in sales, roughly three times over.
The pattern held on Meta, Google and TikTok alike: campaigns at the same spend returned about the same sales, with no channel standing clearly apart.
Predictions of sales from budget landed within about 14% on campaigns held back from the analysis, and returns stayed steady across the budgets tested, from about RM500 to RM12,000.
So the budget can be set to a sales target rather than guessed, funded wherever the product margin beats the return, and scaled with confidence within the tested range.
