Last updated: April 5, 2026

Meta ads deliver SaaS leads at $45-80 CPA, with trial signups at $45-60 and demo requests at $65-80. The key to reducing CAC is retargeting — 60% of SaaS conversions from Meta come from retargeting, not cold traffic.

Trial vs Demo Optimization

Trial campaigns: $45-60 CPA, 8-12% trial-to-paid. Demo requests: $65-80 CPA, 20-30% close rate. Sub-$100/mo products: optimize for trials. $500+/mo enterprise: optimize for demos. Track CPA-to-LTV, not just CPA.

The Retargeting Funnel

Cold traffic converts at 1-2%. Retargeted visitors: 8-12%. Three layers: top-of-funnel content ads, mid-funnel demos and case studies, bottom-funnel trial offers. Allocate 30% cold, 70% retargeting for optimal blended CAC.

Creative Strategies for SaaS

Product demos under 30s outperform screenshots by 2x. Testimonials with metrics ('reduced churn by 34%') beat generic claims. UGC-style 'day in the life' product videos are the top format in 2026.
