How much can a conversion optimization consultant improve my conversion rate?

Conversion improvements vary widely, but experienced CRO consultants typically achieve 10-30% improvements, with some projects seeing 50%+ increases. Results depend on your starting point—sites with major issues often see bigger improvements. Factors affecting results include traffic volume (more traffic = faster testing), current conversion rate (lower rates have more room for improvement), and industry. E-commerce sites often see 15-25% improvements, while SaaS companies might see 20-40% improvements in sign-up rates. The key is consistent testing and optimization over time. A good consultant sets realistic expectations based on your specific situation and focuses on sustainable improvements.
