High CPA can quickly kill profitability—even with decent ROAS. But blindly cutting spend or shrinking audiences won’t solve the problem. Let’s walk through proven ways to lower CPA without harming results.

1. Improve Landing Page Load Speed

A delay of just 1 second can reduce conversions by 7%. Use tools like Google PageSpeed Insights or GTmetrix to optimize.

2. Test High-Intent Audience Segments

Instead of targeting broad interest groups, test:

• Lookalikes based on high LTV customers

• Custom segments (e.g., cart abandoners, video viewers)

• Purchase-intent audiences from search data
  

3. Tighten Location & Device Targeting

Focus on:

• Top-performing cities or regions

• Devices with higher conversion rates

• Excluding underperforming segments
  

4. Refresh Creatives Every 2–3 Weeks

Ad fatigue increases CPA. Test new hooks, formats, and offers consistently.

5. Use Lead Forms or WhatsApp for Mobile

On mobile, people prefer faster options. Try Meta’s lead ads or click-to-WhatsApp if your site isn’t converting.

6. Test Value-Based Lookalikes

If you have enough purchase data, Meta and Google allow LTV-based lookalikes—giving you a better match.

7. Leverage Smart Bidding or ASC

Sometimes automation works better. Test tCPA or ASC if manual setups are inconsistent.

Final Thoughts

Lowering CPA isn’t about doing less. It’s about doing smarter. Test, analyze, and refine—your results will follow.
