High CAC is rarely a media-buying problem. It's almost always a creative, offer, or funnel problem dressed up as one. Here's the order we use to bring it down within 30 days.
1. Audit the funnel before the ads
If your landing page converts at 0.6%, no targeting tweak will save you. Fix headline clarity, hero proof, and a single primary CTA first. A 2x conversion lift halves CAC instantly.
2. Shift budget toward proven creatives
Most ad accounts have a long tail of mediocre creatives draining spend. Pull a 14-day report, identify the top 20% by ROAS, and concentrate 70% of budget there. Then build more variations of those winners.
3. Tighten audience signal
Broad targeting works only when the creative does the qualifying. If yours doesn't, add interest stacks, lookalikes from purchasers (not leads), and exclude existing customers.
4. Introduce a faster offer
A lower-commitment offer (a sample, a guide, a trial) widens the top of funnel and gives the algorithm more conversion data — which lowers CPA across the account within 7–10 days.
5. Cut frequency, raise creative refresh
When the same person sees the same ad 6+ times, CTR collapses and CAC climbs. New creative every 2 weeks keeps frequency healthy and unit economics intact.
