1. The Agency Opportunity: Reselling Enterprise CRO
In 2026, driving traffic to client websites via SEO and PPC is only half the battle. Digital agencies are under intense pressure from clients to demonstrate tangible conversion rate improvements and revenue growth.
However, executing professional Conversion Rate Optimisation (CRO)—including heatmap analysis, session recording reviews, UX wireframing, and statistically significant A/B testing—requires dedicated UX researchers and frontend engineers.
Partnering with a specialized white-label CRO provider allows agency owners to resell high-margin conversion optimization retainers under their own brand at wholesale rates—expanding Monthly Recurring Revenue (MRR) with 50%+ net margins.
