Been cycling through different testing tools but keep hitting walls with sample sizes or delayed reporting.
Need something that actually gives me confidence in the data when I’m pushing changes weekly.
Google Optimize works fine for weekly pushes honestly.
Consider Amplitude Experiment. It offers real-time results and accurate significance calculations. No delays in report refreshing. Focus on key metrics by selecting one primary goal per test. This helps achieve significance quicker with smaller samples. Many tools struggle because users dilute traffic across too many variants. Keeping it simple leads to actionable data in days instead of weeks.
Optimizely gets the job done if you can handle the pricing. Fast results most of the time.
VWO has been solid for me when I need quick turnaround on app funnel tests.
The reporting updates fast enough that I can make decisions within a few days instead of waiting weeks. Their statistical engine seems more reliable than some of the cheaper options I tried before.
Just make sure you set up your events properly from the start because fixing tracking mid test will mess up your data.
