How to Choose the Best E-commerce KPIs for Your Business

Okay, so you’ve learned about the different e-commerce KPIs. But now comes the big question: 

“What KPIs should I pick for my business?” 

Here are some points to keep in mind before selecting your best fit:

Align with Your Business Goals

First things first, understand your business goals. 

Are you focusing on customer acquisition, retention, or increasing average order value? Depending on your objectives, the KPIs you monitor will change. 

For instance, if customer acquisition is your primary goal, metrics like ‘Website Traffic’ or ‘New Customer Rate’ should be on your radar.

Consider Your Industry

A crucial KPI for a fashion e-commerce site may not hold the same importance for an online grocery store. For example, a fashion store might prioritize ‘Return Rate,’ while an online grocery might be more concerned with ‘Inventory Turnover.’

Evaluate Your Business Stage

Is your business in its seed stage, or have you been around the block a few times? 

For newer businesses, focusing on ‘Customer Acquisition Cost’ or ‘Conversion Rate’ might be beneficial. In contrast, more established businesses might look at ‘Customer Lifetime Value’ or ‘Repeat Customer Rate.’

Pick Easy-To-Measure KPIs

Select easily measurable KPIs that offer valuable insights into your business growth. For example, there’s no point in measuring Brand Equity or Perception, as these are difficult to measure given the time and effort. Instead, you should track KPIs like customer lifetime value or conversion rate, as these can give you a clear picture of your business’s performance. 

Don’t track so many KPIs that don’t matter to the business goal and add to the confusion. Select a few that gives you the most useful and actionable information. 

Final Thoughts

Choosing the right e-commerce KPIs is crucial for the success of your online business. These act as your compass, guiding you toward meeting your business goals.

Once you’ve set your KPIs, track those metrics regularly to stay on track and make data-driven decisions.
