After auditing more than 200 ad accounts, we see the same money leaks again and again. The good news: every one of them is fixable in an afternoon.

1. Broad targeting without creative segmentation

Broad audiences work in 2026 — but only when your creative does the targeting. Run distinct angles for each customer persona instead of one generic ad.

2. Ignoring the Conversions API

Pixel-only tracking misses up to 30% of conversions after iOS privacy changes. Pair the pixel with the Conversions API for accurate optimization signals.

3. Killing ads too early

Meta needs roughly 50 conversion events per week per ad set to exit the learning phase. Judging an ad after two days and $20 guarantees false negatives.

4. One landing page for every campaign

Message match matters. A cold prospect and a retargeted visitor need different pages with different promises.

5. No retargeting ladder

Build layers: engaged viewers, site visitors, add-to-carts. Each layer gets a sharper offer.

6. Forgetting creative fatigue

When frequency passes 3 and CTR drops 20%+, refresh the creative — not the audience.

7. Optimizing for the wrong event

If you can, optimize for purchases, not clicks. Cheap clicks are the most expensive thing in advertising.

Fix these seven and most accounts see CPL fall within two weeks — no extra budget required.
