Certain things cannot be measured just by the number of likes and shares.

The way a product is designed, how simple and intuitive it is, the consumers trust in the product, their love and hate towards it, how they interact with other products, and how they use it as time passes.

• Adding new features makes the metrics go up, but it fails when we keep adding newer features, making the application bloated.
• The brand power, of big brands like Apple or Nike, is hard to track on mere numbers, and the goodwill or trust they enjoy due to their past work is hard to put down in metric numbers.
• Current behaviour cannot accurately predict future behaviour due to the inherent complexity and unpredictability of where technology and consumer preference goes.

1. Use retention as a way to assess your market-product fit, as it tells you how valuable the customers find your product after they stop using it.
2. Understand the steps your customers have to take to get to your product, and if you can eliminate extra steps.
3. Focus on key data, and do not waste time on unimportant metrics.
4. Ask yourself what information you want from the customers to increase sales.
5. Understand the metric goals clearly, not just on face value.
6. Use counter-metrics to stress-test your figures.
7. Pair your hard data with qualitative research like usability testing, focus groups and surveys.
