Should I test one element at a time or multiple changes together?
As an e-commerce manager, I'm struggling with conversion rate optimization and unsure about the best approach to testing changes. I want to improve my website's performance but don't know whether I should make incremental, single-element changes or test multiple modifications simultaneously. The uncertainty is causing me to hesitate and potentially miss out on potential improvements. I need a clear strategy that balances scientific rigor with practical business needs and helps me understand the most effective way to run optimization tests.
