Testing the same offer across two language audiences — not just two ad creatives — found a 43% cost gap and where the real winner was.
Two campaigns ran the same offer to two different language audiences. Rather than assuming one message fits everyone, we tested both against each other.
The primary-language campaign came in at RM5.23 per enquiry and carried 61% of all enquiries; the secondary-language campaign, while still comfortably under market at RM7.48, cost 43% more. That gap is the optimization story — not a bad ad, just the wrong emphasis for that audience.
Ad frequency stayed at 1.91× — a genuinely fresh account, with real room to scale the winning campaign before any sign of fatigue.
The same offer tested across both language audiences to find which one actually converts cheaper.
Weekly monitoring surfaced the 43% cost gap between the two audiences early.
Budget weighted toward the winning audience, while the other gets fresh creative to close the gap.
