Answer
Conversion rate optimization (CRO) typically costs between $2,000 and $15,000 per month for agency services, with enterprise programs exceeding $25,000 monthly. In-house teams require salaries for specialists, tool subscriptions, and testing platforms, often totaling $100,000+ annually.
Costs vary based on scope, traffic volume, and complexity. Small businesses may spend $500–$2,000 monthly on tools and freelance help. Larger companies invest in enterprise A/B testing tools like Optimizely or VWO, which charge based on pageviews and features. Some agencies offer project-based pricing, ranging from $5,000 for a CRO audit to $50,000 for a full-year engagement.
