Root Cause Insights

Why is conversion low when CTR and CAC are excellent?

Your outstanding CTR (2.3%) and low CAC ($72) prove you’re reaching the right people with compelling ads at efficient costs. But losing 29 customers/month between click and conversion suggests post-click friction. This pattern typically indicates:

1. Mobile form friction: 62% of Facebook ad clicks are mobile. Complex forms or poor mobile UX kill conversions
2. Response time expectations: Local service seekers want immediate contact options (click-to-call beats forms)
3. Trust signals missing: Post-click landing pages may lack reviews, licensing, emergency availability messaging
4. Form length: Every additional form field reduces conversion ~5-10%

Why this is good news: You’re already paying rock-bottom CAC to reach qualified prospects. Fixing conversion won’t require more ad spend—just better post-click experience. Each 1% conversion improvement adds ~$3,200/month in profit.
