Data without action is just numbers on a screen. The goal of e-commerce analytics is not to track everything -- it is to track the right things and act on what you find.
The Five Metrics That Matter
1. Conversion Rate
What percentage of visitors buy? E-commerce average: 2-3%. If yours is below 1.5%, there are usability or trust issues. Track overall and by traffic source to identify your best channels.
2. Average Order Value (AOV)
How much does the average customer spend per order? Increase AOV with bundling, upsells, cross-sells, and free shipping thresholds. A 10% AOV increase has the same revenue impact as a 10% traffic increase.
3. Customer Acquisition Cost (CAC)
How much do you spend to get one new customer? Include all marketing costs. If CAC is higher than your first-order profit, you need either higher prices, lower marketing costs, or a subscription model for repeat purchases.
4. Customer Lifetime Value (LTV)
How much does a customer spend over their entire relationship? LTV should be at least 3x your CAC. If it is lower, focus on retention, repeat purchases, and loyalty programs.
5. Cart Abandonment Rate
What percentage of carts never convert? Average: 70%. Track this weekly and test checkout improvements to bring it down. Even a 5% reduction translates to significant revenue.
Setting Up Tracking
At minimum, install:
- Google Analytics 4 with Enhanced E-commerce
- Facebook/Meta Pixel for social media attribution
- Google Ads conversion tracking if running ads
- Heatmap tool (Hotjar, free tier) for understanding user behavior
