Your MVP should have analytics from day one. This will allow you to monitor how users use your product. Otherwise, you will be flying blindly. Below you’ll find three tips about setting up metrics:
1) Set up an events-based analytics product. Google Analytics isn’t great to identify what actions your users took when using your product. Were they clicking on that button, were they seeing this particular screen? For this type of insight, you need products such as Mixpanel, Amplitude, Heap, etc.
2) Define your main KPI. A Key Performance Indicator is a number that you track to reflect how your company is doing. Your KPI should almost always be one of two things:
Revenue if you are planning to charge money from your customers.
Usage (like daily active users) if you are not going to charge money.
3) Pick only 5 to 10 important stats. Avoid tracking all that your users are doing. Pick a few simple stats that move your main KPI and educate everyone in your team to access them.
