E-commerce
October 1, 2026
Are you wondering how to choose the right KPIs for your e-commerce business? The answer can be summed up in one sentence: align your indicators with your strategic goals, not with generic metrics. A relevant KPI tells you in a few seconds whether you are gaining or losing ground, without drowning your team in unreadable spreadsheets.
The trap? Copying someone else's dashboard or stacking dozens of metrics that do not reflect your reality. Between standard KPIs (conversion rate, average basket) and custom indicators (sales by category, by channel), you need to find the right balance.
So how do you choose the right KPIs for your e-commerce? On the agenda:
Why standard KPIs are not enough?
How many KPIs to track per dashboard?
How to define a KPI based on your objectives?
Which custom KPIs for your store?
How does Qstomy help track the right indicators?
Let's go.
Summary
Why standard KPIs are not enough for your e-commerce?
Standard KPIs, such as email bounce rate or net margin, are useful for comparing your store against the competition. They provide an overview of the health of your business and identify operational weaknesses. But be careful: they only tell part of the story.
Let's take an example. You launch a new product line aimed at a specific target, say 18-25 year olds. Your site's overall conversion rate may remain stable, while this range completely fails with that audience. A standard KPI will not catch this. However, a custom indicator on sales by demographic segment will alert you immediately.
That's why the hybrid approach is the most effective: combine universal metrics for benchmarking and in-house indicators to drive your strategy. Your teams then align on a common goal, and you avoid false diagnoses.

How many KPIs should you track per dashboard?
The temptation is great to measure everything: sales, traffic, average cart, abandonment rate, customer satisfaction... But too many KPIs kill the KPI. An indicator must be understood in a few seconds, not require an in-depth analysis. It is a signal, not a full report.
The simple rule: aim for about seven KPIs per dashboard, maximum ten. Beyond that, you dilute your team's attention and spend more time interpreting than acting. Each department can have its own dashboard, but each must remain readable.
For example, for your marketing team, focus on acquisition cost, return on ad spend, and conversion rate by channel. For logistics, track delivery time and stockout rate. The goal: that everyone knows at a glance if they are on the right track.
How to define a KPI based on your objectives?
The best way to define a KPI is to start with your annual or quarterly objectives. If your goal is a 5% growth in revenue, your KPI will simply be the year-over-year percentage change. It is a simple, immediately understandable indicator.
But not all objectives are quantifiable. Improving internal communication, for example, cannot be measured by a sales figure. In this case, you can create a KPI based on a satisfaction survey of your teams. The result becomes an indicator tracked over time.
The important thing is to link each KPI to an action plan. If the figure is bad, you must be able to identify the cause. A KPI with no possible cause is just a decorative figure. Ask yourself: what will I do if this KPI drops by 10%? If you do not have an answer, it is not a good indicator.
Which custom KPIs for your shop?
Custom KPIs are those that reflect your specific business. Here are the most common and useful ones for an e-commerce:
Sales by product category: essential if a category has just been launched or is in decline. You can react quickly.
Sales by promotion: track the impact of your promo codes, special events, or contests. You will know what really works.
Sales by channel: compare your website, Amazon, your emails, or your physical stores. You can direct your investments toward profitable channels.
Logistics efficiency: measure delivery times by area. Times that are too long reduce repeat orders.
These indicators give you a detailed vision, but they must remain limited in number. Choose those that correspond to your current challenges.
Track sales by product category
Tracking sales by category is a powerful KPI, especially when a range is new or losing momentum. You can then allocate your marketing budgets accordingly, or launch targeted corrective actions. For example, if a "summer" category drops in September, you know you need to clear stock or redirect your campaigns.
To set up this KPI, use the reports from your e-commerce platform or Google Analytics. Segment by category, sub-category, or even by product. The important thing is to compare performance over time, not just in absolute value.
This KPI is all the more useful as it combines with others, such as the conversion rate by category. You then identify the categories that attract traffic but do not convert, and you adjust your product pages or your prices.
Measure the impact of your promotions
Promotions are a classic sales lever, but they can also eat into your margin. Measuring sales by promotion tells you if a promo code actually generated incremental sales or if it simply cannibalized purchases that would have happened anyway.
This KPI covers special events, unique codes, contest entries, etc. You can even compare the effectiveness of different types of promotions: percentage discounts, free shipping offers, free gifts. Each format has its impact.
By linking this KPI to your margin, you avoid overly generous promotions that attract unprofitable customers. It is an indicator that protects your profitability while boosting your sales.
Analyze sales by channel
Your sales come from multiple channels: your website, marketplaces like Amazon, your email campaigns, your social networks, or your physical stores. Knowing the performance of each channel is essential to guide your marketing strategy. A channel that brings in little but costs a lot must be optimized or abandoned.
For this KPI, segment your sales by acquisition source. Use UTM parameters for campaigns, and the native reports of your platforms. Compare the revenue, but also the margin and the acquisition cost per channel.
This tracking helps you decide where to invest your next advertising dollars. For example, if your emails generate a better return than your Facebook ads, you can rebalance your budget. It is a KPI that guides your daily decisions.
Optimize logistics efficiency
Logistics is a key factor in customer satisfaction. A KPI on delivery efficiency can include average order processing time, on-time delivery rate, or transport cost per order. These metrics show you if your provider is performing well or if you need to change.
Too long transit times for certain geographical areas can reduce repeat orders. Customers expect fast delivery, and a delay can drive them to a competitor. Tracking this KPI by region allows you to identify problem areas.
This KPI pairs well with the stockout rate. If a product is out of stock, you lose an immediate sale, but potentially also a loyal customer. Good logistical tracking protects your reputation and your turnover.
Evaluate customer satisfaction
Traditional customer service KPIs, such as the number of calls or the average call duration, do not tell the whole story. A call to place an order is short, while a call for a complaint is long. Comparing durations does not indicate satisfaction. It is better to survey customers after each interaction.
Implement post-call or post-chat satisfaction surveys. Ask for a rating out of 10, and track the evolution of this rating over time. It is a simple KPI, but directly linked to the customer experience.
You can also measure the first-contact resolution rate. If a customer has to call multiple times to resolve a problem, their satisfaction drops. This KPI helps you improve your internal processes and train your teams.
The basic principles for creating KPIs
There are no strict rules for creating KPIs, but a few common-sense principles. A KPI must indicate success or failure and be linked to a report or dashboard that helps identify the cause. Without that, it is useless.
Keep your KPIs simple and understandable in a few seconds. If a metric requires a five-minute explanation, it is too complex. Focus on metrics that your team can visualize and interpret quickly.
Finally, review your KPIs regularly. Your goals change, your metrics must follow. A KPI that is relevant today may become obsolete in six months. Adapt your dashboard to your current strategy.

Check your dashboard before finalizing it
Before finalizing your dashboard, check these points:
Strategic alignment: does each KPI correspond to a specific goal?
Limited number: do you have fewer than ten KPIs per dashboard?
Actionability: do you know what to do if the KPI changes?
Readability: can the indicator be understood in a few seconds?
In brief
Choosing the right KPIs means finding the balance between standards and custom solutions, and keeping a dashboard readable. Track your goals, not someone else's.
