As an ecommerce seller, you have access to data-driven insights that can help you make informed business decisions.
But knowing which metrics to focus on and, most importantly, how to act on them can make the difference between growing your business, or staying stuck.
If you’re not a seller analytics pro, but you know you NEED to start taking these insights seriously, keep reading. In this quick guide, we’re reviewing the key data points you need to track. (And how to use them to grow and improve your ecommerce business.)
What seller analytics should I track as an ecommerce seller?
Use real-time data insights to gauge opportunities and risks your company might be up against.
Here’s what to track and what to do about it:
Conversion Rate (CR)
Track your CR often to see the percentage of visitors who make a purchase. You can do this by dividing the number of conversions by the total number of visitors. Then, multiply the result by 100.
One of the most valuable aspects of seller analytics is having access to insights that can help you improve your conversion rate. Behavioral Intelligence (BI) Analytics can uncover why customers are visiting your site but not buying.
This includes insights into:
- Which pages or steps in the funnel are causing friction
- Customer satisfaction levels (via reviews and ratings)
- Which product listings they scroll past
- Checkout abandonment rates
It can also flag data by customer segments, such as most purchased products, product/feature preferences, abandoned carts, and product return percentage.
Our advice? Perfect the user experience.
Use heat maps, session recordings, and checkout funnel analysis to identify areas where customers drop off, then test different strategies to improve those specific stages.
For example, if you notice many customers abandoning their cart at the shipping options stage, try offering free shipping or simplifying the options to see if it increases conversions. (Still make sure they can cancel anytime, though, so you don’t bruise trust.)
➜ Small improvements in conversion rate can lead to substantial revenue growth, especially when scaled across high-traffic pages.
Sales volume (SV)
Track your SV to see how many items you’re selling over a specific period. This helps you evaluate your business’s performance based on quantity sold, not revenue.
Next, use your sales volume data to guide your pricing strategy.
Analyze how price changes affect the number of units you sell and adjust your pricing margins to maximize both volume and profit.
How to monitor your sales volume and adjust your pricing strategy
Here’s a simple process to follow:
- Check your sales volume to understand current performance.
- Use price elasticity analysis to see how changing prices affect sales and profit margins.
- Review competitor pricing using your analytics tool to ensure you’re within a competitive range.
- Once you’re competitive, run A/B tests. For instance, test $19.97 vs. $21.97 to find the price that generates the most profit.
You can also track sales volume variance to adjust your strategy for better inventory management and sales planning. (This measures the difference between the actual units sold and the number of units you expected to sell.)
And if speed is a priority, calculate your sales velocity to see how fast a product is selling (e.g., units sold per day or week). More specifically, this shows you how fast deals move through your sales pipeline and how much revenue you’re generating in a given period.
You can calculate it with this formula: (Number of Deals x Average Deal Size x Win Rate) ÷ Length of Sales Cycle
➜ Sales volume and the other relevant metrics we mentioned here are key signs of your business’s financial health. They reveal how well you’re selling products and measure how well your marketing, sales team, and business strategy are working.
Inventory Turnover Rate (ITR)
Use your seller analytics to get real-time data and details on which products are performing well and which aren’t.
Checking your ITR helps you:
- Identify slow-moving inventory that needs to be marketed better or cleared out
- Manage stock levels more effectively to avoid both overstocking and stockouts
- Spot best-selling products and scale inventory accordingly
Do this to track your inventory turnover rate and predict the demand cycles for products so you can make just-in-time inventory decisions.
For manufacturers, using the best order management software for manufacturing can also help keep sales orders, inventory levels, and production planning aligned as demand changes
For example, if you see a spike in demand for summer clothing, you can increase stock ahead of time to meet that need and get more sales.
➜ Efficient inventory management based on data helps sellers avoid losing sales because of running out of stock. It also stops them from wasting money on unsold items and storage fees.
Average Order Value (AOV)
Watch your AOV to get actionable insights about what customers like to buy and how they’re spending their money.
A high AOV suggests that customers are purchasing more expensive products. Or maybe opting for bundles, upgrades, or upsells. This is a great indicator that your upselling and cross-selling strategies are working, so keep using them! ✅
For example, if your AOV is higher during sales events or with certain product bundles, consider offering similar deals more frequently.
Or try experimenting with different product pairings to increase total sales.
It’s also important to give shoppers plenty of ways to pay, allow refunds within a reasonable time, and list any other fees they’re responsible for. These details lower barriers to entry and give users more autonomy, which can encourage a higher AOV.
➜ A higher AOV means more revenue from fewer transactions, which can help you improve your net profit even without increasing customer traffic.
Repeat Purchase Rate (RPR)
Take a close look at your RPR sales data to gauge how many customers make multiple purchases from your store within a specific period.
To increase RPR, consider creating loyalty programs, offering discounts for repeat customers, and sending personalized reminders. (Notify customers about these via targeted email campaigns, in-app notifications, or push notifications.)
You can also run retargeted ads.
For instance, if a customer bought a product a few months ago, send a follow-up email with a related item. Or instant access to a discount code to encourage another purchase. Or follow them around the web with an irresistible offer — like a buy-one-get-one deal.
➜ A higher RPR indicates customer satisfaction and brand loyalty, meaning your customers find value in your product lines and are more likely to return.
Return On Ad Spend (ROAS)
Track your ROAS by campaign, channel, and audience segment to see how much revenue you’re generating for every ad dollar spent.
If you’re spending $1,000 on ads and making $1,200, your ROAS is technically positive. But is it good enough? Not if you’re barely covering costs or missing higher-return opportunities.
How to optimize your ROAS
To optimize your ROAS, regularly review your ad spend and profit across platforms. Adjust your bids, refine your target audience, and experiment with different ad creatives and copy to see which combinations lead to higher returns. Using a reliable Facebook ad maker can also help you quickly test multiple creative variations without increasing production time or costs.
For example, if you find that Facebook ads targeting a specific demographic generate higher returns than LinkedIn ads, allocate more of your budget to that platform.
➜ ROAS helps you move from guessing about your ad campaigns to scaling what works. A high ROAS means your targeting, timing, and messaging are aligned and worth doubling down on.
Customer Acquisition Cost (CAC)
Monitor your CAC to understand how much it costs to gain a new customer.
This metric includes everything you spend on marketing, sales, and promotions divided by the number of new customers acquired in that period.
A lower CAC means you’re efficiently acquiring new customers without overspending. Compare this to your CLTV to make sure you’re not cutting too far into your profit margins. (More on CLTV further below.)
For example, if your CAC is too high, check which ads or audience groups are costing more than others but not converting well. You might discover that ads targeting a narrow audience are surprisingly more expensive and aren’t leading to sales for your recently built ecommerce app. Broadening your targeting or testing different keywords, in this case, might help you lower your costs.
➜ Keeping your CAC in check protects you from overspending on customer acquisition and helps you use your marketing budget more efficiently.
Customer Lifetime Value (CLTV)
Measure your CLTV to understand how much a customer is worth during their relationship with your company.
A high CLTV means customers are sticking around, making repeat purchases, and engaging with your business often, so don’t skip this.
How to apply data analysis to boost your CLTV
Use customer segmentation in your analytics to target high CLTV customers with personalized offers and loyalty rewards.
For example, offer your high-value customers exclusive deals, early access to new products, and personalized product recommendations to increase their lifetime value even more. Make sure they know you’re rolling the red carpet for them by using terms like “VIP” or “loyal customer” in your marketing messaging.
Besides, if you’re looking for different tools to help with data collection and segmentation for these loyalty programs, you may want to explore Formstack alternatives.
➜ A higher CLTV means greater long-term revenue potential. Focusing on increasing CLTV can help you build a more sustainable and profitable business model.
Wrap up
Tracking the valuable insights in your seller analytics tool is key to getting the full picture of your true profitability. Without it, you’re simply guessing your way through business, which isn’t a strategic approach.
Be sure to regularly monitor these metrics to make smarter, more informed decisions, refine your strategies, and encourage more sales.
