Digital marketing evangelist Avinash Kaushik says, “Most businesses are data-rich but lack information.”

Hence, the importance of eCommerce key performance indicators (KPIs)!

Having so much data at one’s fingertips is incredible, but time and again, we see how overwhelming it is for business owners who have no idea how to read Google Analytics or what to keep track of.

This blog will discuss everything you need to know about the most important eCommerce KPIs.

What Are Ecommerce Key Performance Indicators?

Main KPIs

eCommerce KPIs are important performance metrics that may be used to assess your company’s performance. They can be used to keep track of your internet business growth and sales, as well as the net promoter score of your business. KPIs can be established based on your company’s goals.

So, by combining the number of sales you’ve made in addition to your website traffic, you’ll arrive at what we call a conversion rate. It’s determined by taking the number of sales, dividing it by the number of visitors, and then multiplying the result by 100.

Thus, a KPI might be to improve conversion rates by 20%. Therefore, it uses specific metrics to gauge achievement.

Why are eCommerce KPIs like conversion rates important? With proper conversion rate optimization services, you’ll be able to increase revenue per visitor, acquire new customers and grow your business.

Plus, tracking the most important eCommerce metrics allows you to spot patterns you might not have noticed otherwise.

Why Are Ecommerce KPIs so Important?

KPIs help achieve goals

If you have an online store, you may utilize promotional KPIs to find out what products are being sold and who is buying them, as well as how and why. Benefits include writing quality product descriptions, gaining insight into product development, and marketing more effectively in the future.

KPIs are purely objective, and devoid of emotions. They are somewhat predictive in nature, allowing online retailers to better understand their customer’s end-to-end experiences and transform data (insights) into actionable business strategies.

Ecommerce KPI Mistakes to Avoid!

Tracking the wrong key performance indicators can doom your eCommerce business. KPIs are strategic decision drivers, not accounting mechanisms. They should lead and not just track digital initiatives.

The seven common mistakes eCommerce store owners make when it comes to KPIs are:

  • Setting vague KPIs;
  • Tracking too many KPIs;
  • Having too many KPIs dependent on external factors;
  • Not defining those responsible for KPIs;
  • Focussing too much on the process and not the results;
  • Not linking strategic goals and KPIs; and
  • Having the same KPIs as other companies.

Measuring the wrong KPIs may paint an inaccurate picture of your eCommerce store’s performance. Vanity metrics, for instance, can make your company look good to others, but they do little to move the needle or inform future strategies.

A typical example of a vanity metric is tracking page views, but not conversions. Knowing how many people visit your pages is great; however, it doesn’t indicate whether your visitors are becoming new customers or if your landing pages are effective.

As your company meets important eCommerce metrics, you’ll need to adjust your KPIs to reflect newfound growth. It’s normal to take time to reach your business goals, however, having objectives to work towards keeps both you and your team members motivated.

Ecommerce KPI Mistakes Examples

Now that you’re in the process of determining which KPIs are appropriate for your company, there are a few you should stay clear of. The key performance indicators below often fill business owners and their marketers with a deluded sense of achievement.

1. Website Traffic Without Conversion Rates

High traffic with low CRO

Your eCommerce website is your business’s primary hub to make sales. The more visitors it receives, the higher its conversion rate should be.

Conversion rate is a key performance indicator that refers to the process of increasing the percentage of users or website visitors to take a desired action.

Generally, it involves taking one of the following steps:

  • Subscribing to email newsletters;
  • Completing lead capture forms; and
  • Making purchases.

Monitoring site traffic is important but is not necessarily indicative of increased sales. If prospective customers aren’t converting, they may as well not be there in the first place.

Instead of just getting more visitors to your eCommerce site, try to focus on your customer retention rate. Optimizing this metric convinces more people to stay with you for years to come.

2. Calculating Profit Without Factoring in Costs

B2B companies typically spend between 2 to 5 percent

The old axiom goes: “You need to spend money to make money,” which is true, yet a lot of new eCommerce businesses focus on gross profit without looking at net income. Many don’t even consider a marketing budget.

For fledgling companies, exposure is possibly the most critical component needed to grow a brand. Establishing your eCommerce business is easier when you employ strategies like paid advertising, SEO-related campaigns and email marketing tactics.

Businesses solely focused on their bottom line have a tendency to squander valuable funds that could be put into other important business areas like marketing.

Industry standards dictate marketing budgets are a percentage of projected revenue. B2B companies typically spend between 2% to 5% of their total revenue on marketing, whereas B2C companies allocate between 5% to 10%.

3. Thinking Marketing Success Equates to Profit

Although it’s thrilling to know you’ve just surpassed 5k followers on Instagram or that you’re being ranked on the first webpage of Google with the most popular keywords you’re tracking, those numbers don’t necessarily equal sales.

These key metrics are positive indicators, but should never be mistaken for conversions or net profit. Acquiring a bird’s eye of your company can help you identify gaps and alter your strategy when needed.

Do More KPIs Mean More Sales?

Steps in the KPI process

KPIs aren’t merely relegated to marketing. A company can have many KPIs to improve and measure customer service, talent acquisition, employee upskilling, and so on. Therefore, you have to distinguish marketing KPIs from overall business KPIs.

Only measuring marketing KPIs isn’t a reliable representation of your company’s financials. Every department should have unique KPIs. Most areas of business have between four and 10! Of course, these key metrics can be further segmented into mini-goals, too, etc.

All KPIs start with strategy. Experienced business professionals will tell you which KPIs matter most, depending on your business and industry. When developing your marketing KPIs, the key consideration is always whether measuring them will actually assist business growth.

You don’t need tons of KPIs, just the right ones!

Helpful Ecommerce KPIs to Track

What is the most important KPI to track

Every eCommerce KPI you track should:

  • Be consistently and accurately quantifiable;
  • Occur in real-time;
  • Make an impact; and
  • Have action items that permit you to make adjustments as you go.

We recommend keeping track of the following KPIs to monitor your eCommerce business:

Useful Ecommerce KPI Examples

Churn Rate

Sometimes called attrition rate, churn rate is the rate at which customers stop buying from you over a period of time. It may also apply to the number of subscribers who cancel or don’t renew a subscription.

To determine your churn rate, you subtract the remaining customers at the end of the month from the total number of customers you had at the beginning of the month and multiply it by 100.

You can also divide this number by 12 and then divide the result by 12 to determine your annual churn rate.

Time Between Purchases

This is the average number of days a customer takes between purchases over a 365-day period.

Take the purchase frequency of the customer and divide it by 365 days. If you notice the number of days passed between transactions is greater than you’d like it to be, you may have to work on improving your marketing campaigns and sales funnel to increase profits.

Additionally, getting more customers to buy from your eCommerce store more frequently also builds a loyal customer base.

Average Order Value (AOV)

This is the average amount of money customers spend on every order. To work it out, simply take the total amount divided by the number of orders you’ve received.

AOV directly correlates with how much revenue you make. It informs your marketing and pricing strategy and directly impacts revenue growth.

Cost of Goods Sold (COGS)

COGS are all the direct costs incurred to create the products or services a company sells. Some tend to be variable — for example, materials and labor — while others are fixed, like storage space rent.

To determine this figure, take the cost of your inventory at the beginning of the year and add it to other inventory costs acquired during the year. Then, subtract the end inventory value at the end of the year.

Gross Profit

The most important eCommerce KPI to monitor is gross profit. It’s calculated by taking the cost of selling goods after subtracting your total value of sales.

Gross profit helps determine the general profitability of your eCommerce business. It also shows how effectively you use raw materials, labor and other supplies to make and sell your products and services.

Customer Acquisition Cost (CAC)

How much will your eCommerce store invest to gain an additional customer? Customer Acquisition Cost provides insight into the capital required to increase your customer base.

All internet-based businesses strive to keep CAC as low as possible to maximize profits.

To calculate CAC, take the sum you’re spending on new customer acquisition and subtract it from the total number of new customers acquired.

Ideally, CAC should be 3:1, meaning the value of your customers must be three times more than the cost of acquiring them.

Repeat Purchase Rate

This is the number of people who visit your site to make repeat purchases. A healthy repeat purchase rate indicates you’re providing increasing value to customers and reveals a degree of customer loyalty.

It is calculated by dividing the total number of customers who have purchased products more than once by your total number of customers.

Shopping Cart Abandonment Rate (CAR)

Roughly 70% of shoppers don’t complete a transaction. When online shoppers add products to their shopping carts but don’t buy them, we call this shopping cart abandonment.

There are a couple of reasons for this: long delivery times, lack of brand trust and additional shipping costs.

To improve CAR, you can streamline the checkout process, offer popular payment methods, and free shipping.

You can calculate CAR by taking the number of transactions completed and dividing it by the number of abandoned carts. Multiply by 100 to determine the percentage.

Shopping Cart Conversion Rate (CCR)

On the flip side, it’s beneficial to keep track of the frequency at which your shopping carts checkout. It helps you identify where your sales funnel works.

To figure out this KPI for eCommerce, take the number of conversions and then divide that number in relation to the total number of people who visit your website. Thereafter, multiply this total by 100 and determine the conversion rate for your carts.

Ecommerce Conversion Rate

Conversion rate optimization is a critical eCommerce KPI. To recap: it’s the percentage of users who visit a website and take a desired action, like making a purchase or filling out a form.

More often than not, it is used to determine how many website visitors land up making a purchase.

To figure out the conversion rate, calculate the total number of visitors to your site and divide it by the number of conversions. Then, multiply that number by 100.

You can determine different conversion rates according to the particular conversion goals you’re following. For instance, you could be tracking various rates of conversion for lead capture forms, telephone calls, the use of social media, and more.

Average Profit Margin

The average profit margin is a reference to the amount of net profit you’ve earned during a specific time. To work out this eCommerce KPI, you must calculate your gross profit and then divide it by your revenue.

5% is generally considered a low-profit margin, 10% is healthy, and 20%+ is high.

Your profit margin represents the overall financial health of your business. Remaining fiscally healthy is always attractive to potential investors.

Revenue-per-Click

Revenue-per-click is calculated as follows: total income divided by the number of clicks you receive for the duration of a specific campaign.

Comparing what you earn per click provides a good indication of the profitability of a given keyword. Earning more revenue can justify an increase in ad spend, whereas a loss often means marketing spend should be reallocated.

Customer Lifetime Value (CLV)

Every person who contributes a dollar amount to your company has a lifetime value metric. Focussing on establishing an excellent relationship with your clients and ensuring high customer satisfaction will increase the customer lifetime value of each client.

To determine customer lifetime value, calculate the annual net profit contribution of the customer multiplied by the average number of years that they have been purchasing from you, and then subtract their acquisition cost.

CLV helps companies balance short and long-term marketing goals, and have a better grasp of their financial return on investments.

Purchase Frequency

This key performance indicator is the number of purchases a customer makes over a period of time. It can be a useful KPI for assessing how loyal customers are to your company and will pinpoint the most successful products, as well as those that require additional marketing.

To calculate purchase frequency, divide your total number of orders by the number of unique customers for the same time frame.

Add-to-Cart Rate

This lesser-known KPI is the percentage of visitors who place at least one item in their cart during a session.

As an eCommerce metric, it is useful to track since it tells you about the success of your product selection, UX design and general marketing efforts.

To figure out this number, simply take all the times that a customer has added items to their cart and then subtract it from the total number of their sessions.

How Often Should Ecommerce KPIs Be Evaluated?

KPIs evaluation

As with most responses regarding internet marketing, the answer is dependent on several variables like:

  • How well-established is your online store or eCommerce company?
  • Have you just launched, or do you have a loyal following?
  • Do you have products requiring seasonal promotion?

Furthermore, the frequency with which you check your KPIs is contingent on the KPI. Some require intensive monitoring, while others are less so inclined.

Weekly

Certain metrics should be evaluated on a weekly basis to monitor and track progress. For instance, web traffic or participation on social networks, or total impressions.

Any metrics with paid ads that have, let’s say, a three-month campaign life also requires constant monitoring because you can pivot and adjust your marketing campaigns more quickly, especially if a particular campaign is time-sensitive.

Shorter campaigns may need daily or even bi-weekly monitoring.

Bi-Weekly

If you’d like to collect more data than a snapshot of weekly KPIs, think about tracking certain data points biweekly. This gives you a more precise representation of the numbers.

Examples of biweekly KPIs include the average value of an order as well as customer acquisition costs, or shopping cart abandonment rates.

Monthly

Cost-per-lead, search engine rank based on your SEO campaigns, average email click-through rates and social media metrics are good to track on a monthly basis.

We suggest this time frame because something like SEO won’t yield results in a day or even a week. Checking keyword rankings at the end of the month is also a good idea to determine if your target keyword selection is working.

Quarterly

Quarterly KPI analysis can help optimize a digital marketing plan and provide an overall picture of how your business is growing. These metrics also reveal more significant patterns and trends affecting your company.

Common KPIs to monitor each quarter include customer lifetime value, as well as the average profit margin and the rate of repeat purchases.

Which KPIs Should I Track if I Have Minimal Time?

Honestly, tracking KPIs is not only critical to a business’s success, but also to its survival. If you really have no time to get stuck into granular data, we recommend hiring a digital marketing agency to do the work for you.

It’s worth the investment and will undoubtedly improve your business. Remember, the digital world is fast-paced, and it’s an agency’s business to keep track of industry changes, customer markets, and target audience behavior.

Online businesses with limited resources would do well to keep track of these key performance indicators:

Cost-per-Acquisition and Customer-Lifetime-Value

As we mentioned earlier, you have to invest money to acquire customers. There just is no way around it. Because your marketing efforts cost money, you should keep track of them.

Monitoring cost-per-acquisition and customer lifetime value is essential to your business’s financial health.

It’s basically the difference between how much you have to spend to get customers and how much they’re willing to invest in your company throughout their lives.

The link between the two data sets is vitally important. For instance, if you pay $50 to gain an additional customer, yet their lifetime value is $45, this indicates the cost-per-acquisition is excessive.

If this was to continue across the entire scope of your company, then it would not be worthwhile having an online store in the first place.

It is ideal for eCommerce businesses to have countless customers who have a greater purchasing longevity than its acquisition costs.

This is especially true for eCommerce businesses that have a subscription model with the potential to maximize their return on the investment they make each month.

As a general rule of thumb, when reviewing the results of the KPIs for eCommerce, make sure you begin by looking at your cost to acquire customers as well as their value over time.

Average Order Value (AOV)

This KPI offers insight into how much profit an average order from your site visitors generates.

When you are calculating this number, be sure to look at the time frame like a month, one quarter and even a year to determine the effectiveness of your sales strategies.

If your store doesn’t attract loads of customers, but the average order value is very high, that’s a great thing. The most efficient method for an eCommerce store to boost revenue isn’t to get new clients but to maximize the spending habits of repeat customers.

Repeat purchasers usually have the highest spending, when compared to a customer who has only made one purchase and is likely never to do it again.

Customer AOVs can also help determine shipping limits. For instance, if you observe your average purchase is worth $40, you may offer free shipping on orders of over $50 to encourage more spending.

Be Ready to Revise Your Ecommerce KPIs

As your business grows, so do your KPIs. You should always be willing to tailor your list of eCommerce metrics when the following happens in your business:

  • Strategic goals change;
  • Team or department goals change;
  • Goals have been achieved, and performance is monitored only for exceptions, not improvements;
  • You realize a KPI isn’t a good match for your eCommerce platform goals; and
  • The KPI drives data manipulation or is a vanity metric.

Reviewing KPIs is a normal business activity. If something isn’t working, you can change it. Just do it sensibly.

This process also depends on two things:

  1. How fast your business develops. If you’re growing slowly, but steadily, then you probably won’t need to update your KPIs as frequently.
  2. Your customer purchase cycle. Businesses with short buying cycles should revisit their KPIs often. Unless you’re a B2B business with a two-year buying cycle, for example.

Ecommerce KPIs Help With Conversion Rate Optimization

5 steps to improve conversion rates

Conversion rates are a tough goal to master. Ideally, you want your website to work smarter rather than harder to generate more qualified leads and customers. Thankfully, our expert team can show you how.

Why High Conversion Rates for Ecommerce Are a Challenge

A sizable number of eCommerce websites have the same issue — low conversion rates.

From targeting the wrong audience to using an ill-suited marketing channel or having a poorly designed website — the reasons for low conversion rates are many. Often, it’s a combination of factors that have a knock-on effect, which is why achieving high conversions is no easy feat.

Websites with high traffic but low conversion rates typically have ineffective calls to action, bad user experience, a lack of clarity around the business’ value proposition, or copy that isn’t persuasive enough.

Here are our top tactics to improve your conversion rates and grow your business.

1. Set Clear Ecommerce Key Performance Indicators

As the saying goes, “failing to prepare means preparing to fail.” The first thing we do with all our clients is to assess their current online statuses and then help them set clear marketing goals. Remember, a conversion is the point at which a recipient of a marketing message performs the desired action.

So, it’s not enough to say you want to improve conversions. Do you want to improve sales or newsletter subscriptions? A business can also have more than one conversion goal. For example, “increase sales by 20% in three months” and “increase newsletter subscriptions by 45% in six months.”

2. Write Compelling Product Descriptions

The majority of eCommerce product descriptions are boring, dull, and lackluster. A good description explains what a product is, highlighting its key features and benefits in an effort to convince people to buy it.

Most make the mistake of assuming a product description’s only purpose is to “describe,” but it’s also there to:

  • Qualify: Help shoppers quickly decide if your product is valuable to them.
  • Persuade: Convince customers why they should buy your product.
  • Boost SEO: Optimized with the right keywords, your product pages stand a good chance of showing up in search engine and Amazon results.

If possible, include social proof. Showcasing awards won, endorsements and positive reviews illustrate others trust you and convince new customers to click “buy product.”

3. Invest in Email Marketing for Ecommerce

Many businesses don’t pay enough attention to top-0f-funnel micro conversions which affect purchases. Email marketing, for instance, is a multi-level tactic that starts with capturing a prospect’s contact details and strategically following up with a series of emails, sharing brand and product information and product to encourage purchases.

Building a list of email subscribers helps your business in the following ways:

  • Expands your leads;
  • Collects important 1st party data used to shape future campaigns; and
  • Converts those leads into customers, driving more revenue.

To capture email leads you can hold giveaways, provide discounts for newsletter sign-ups, and embed sign-up forms on key website pages. It’s also possible, with automation software, to segment your target audience and send personalized messages to them based on their interests and interactions with your brand.

4. Don’t Forget About Ecommerce Remarketing Strategy

As you know, not every customer will purchase something on their first visit to your website. Enter remarketing. This tactic involves showing ads to people who have already visited your website. Remarketing has a high conversion rate because ads are highly personalized and based on items potential customers have already shown an interest in.

Customers retargeted with ads are 70% more likely to convert! Understand ordinary consumers see up to 10,000 ads online every day. Remarketing gives them a gentle reminder to finish what they started on your website while reinforcing your branding and messaging to them every time they encounter your company online.

5. Publish Product Line Comparisons

Today’s consumers are accustomed to convenience. They want to purchase goods with the least amount of friction. For instance, in your emails and on your website, you should help customers with their buying decisions by offering comparative information that simplifies their purchasing choices.

Product comparisons are essentially simpler versions of competitor analyses. The aim is to compare two products in a way that readers can instantly grasp. This enables you and your visitors to see where your items are better than your competitors.

Hire the Ecommerce KPI Experts

Increasing your conversion rate is essential to expanding your business and creating repeat buyers. A high conversion rate lowers customer acquisition costs by deriving more value from the visitors and users you already have. When you optimize your conversion rate, you increase revenue per visitor, acquire more customers, and grow your business.
