Small tests require a much bigger sample size to determine the winner. Big companies like Google or Amazon can do very small tests because they have a huge number of visitors every day. However, it’s almost impossible to do them in your small startup.
The only thing that makes sense is to do only those experiments that can have a huge impact, for example, that can improve overall conversion by 30%.
In the early phase of growth, focus on experiments that will have the greatest impact on growth in the least amount of time.
It’s not about testing as many ideas as possible.
Don’t do experiments that have a low impact on growth.
You may start doing these later, when even a small improvement will be significant.
