7 Best Conversion Rate Optimization Courses for CRO & Experimentation
Conversion rate optimization is about more than changing buttons or landing page copy. Good CRO combines customer research, analytics, psychology, experimentation, and statistics to understand why people convert and what to improve.

Contentsquare’s 2026 Digital Experience Benchmark, based on 99 billion sessions across more than 6,500 websites, found that traffic fell 3.8% year over year and conversion rates fell 5.1%. Returning visitors also converted at 2.9%, compared with 1.7% for new visitors.
