Product analytics guides: choosing a tool, implementation and SaaS metrics
These guides are for product, growth and data people at startups who want product usage data they can make decisions with. The first section helps you decide when you need a product analytics tool and which kind fits, including warehouse-native options and experimentation. The comparison section puts Mixpanel, Amplitude and PostHog side by side, including Amplitude against PostHog, on features, AI assistants, APIs and pricing at several event volumes. The implementation section covers the first events to track, identity merge, migrating from GA4 or Heap and the mistakes that break each tool. The metrics section defines marketplace metrics, activation, cohort retention, net revenue retention, CAC payback and the LTV to CAC ratio with formulas you can check. The last section covers mobile app attribution, SKAdNetwork and choosing an MMP such as AppsFlyer or Adjust. If you want analytics implemented or audited, see our product analytics service.
