Key takeaways

  • Test three new hooks every week
  • Verify Pixel and Conversions API before changing budgets
  • Consolidate small ad sets to speed up learning
  • Match your landing page to the ad promise
  • Refresh creatives before frequency climbs

Rising cost per acquisition is the most common complaint we hear from new clients. The good news is that it is usually fixable without cutting your budget.

Start with your creative, not your targeting

Meta’s algorithm now finds buyers on its own. What you control most is the creative. Weak hooks and generic visuals push your CPA up faster than any audience setting.

Test at least three new hooks every week. Keep the offer the same and change only the first three seconds.

Fix your tracking first

If Meta cannot see your purchases, it cannot optimise for them. Check that your Pixel and Conversions API are both firing and that events are not duplicated.

Consolidate your campaigns

Too many small ad sets split your data and slow learning. Fewer campaigns with more budget each usually perform better.

Match the landing page to the ad

If your ad promises a discount and the page opens on a generic homepage, people leave. Send them to the exact product or offer.

Watch frequency and refresh early

When the same person sees your ad five or six times, results drop. Refresh creatives before performance falls, not after.

Quick checklist

  • Three new hooks tested weekly
  • Pixel and Conversions API verified
  • Campaigns consolidated
  • Landing page matches the ad
  • Frequency checked every week

Small, steady fixes beat big budget changes. If you want help auditing your account, get in touch for a free proposal.
