Your e-commerce website is launched — but are you sure it’s actually working? That’s where metrics and KPIs come into play. Metrics provide you with raw data (such as sales figures), whereas KPIs indicate to what extent you’re achieving target goals (such as reaching $100K/month in sales). Collectively, they reveal to you what works, and what doesn’t, and how to do better.
Why monitor them?
Monitoring ecommerce metrics enables you to:
- Understand customer behavior
- Enhance conversions and retention
- Optimise marketing spend
- Plan for long-term growth
Now, let’s consider the 10 most significant e-commerce metrics every company must monitor.
