eCommerce growth funnels

In today’s interconnected world, eCommerce is definitely the high street. The rapid expansion of the internet has brought about a significant shift in consumer behavior, with global eCommerce sales expected to reach $6.9 trillion by 2024.

Nonetheless, in the fiercely competitive environment of eCommerce, businesses must learn to maximize every interaction. The key to turning browsers into buyers and one-time customers into repeat customers lies in the art and science of eCommerce growth funnel optimization.

A growth funnel maps the conversion path of potential customers, from their first interaction with your brand, through the decision-making process, all the way to the point of purchase, and beyond. Understanding how to effectively navigate this journey can mean the difference between the thriving success of your eCommerce business and being left in the dust of your competitors. 


How to Build Your eCommerce Growth Funnel

Building an eCommerce growth funnel is akin to constructing a blueprint for your customers’ journey that should ideally culminate in conversion and customer loyalty.

Key metrics and goals for each stage of the funnel

Let’s delve into the essential stages of an eCommerce growth funnel and the key metrics you should be following for each of them. 

Awareness stage

In this initial stage, your goal is to attract as many visitors to your site as possible. 

The strategies you deploy here are crucial, as they set the tone for all subsequent funnel stages:

  • Search engine optimization (SEO)

  • Pay-per-click (PPC) advertising

  • Social media marketing

  • Content marketing

  • Influencer marketing

For instance, the digital fitness platform, Peloton used influencer marketing to build awareness. They partnered with influencers and celebrities in the fitness industry, leveraging their followings to increase brand exposure. The influencers would showcase the Peloton bikes and classes in their social media posts, making their followers aware of the brand.

Key metrics to monitor in this stage:

  • Website traffic

  • Social media reach and engagement

  • Ad click-through rates

  • Brand mentions

Consideration stage

Once a visitor lands on your site, the next step is to pique their interest in your products or services. This involves high-quality product images, compelling descriptions, customer testimonials and reviews, and FAQs. Video demos or tutorials can also be a useful tool in this stage.

Take Apple, for instance. Their product pages are well-known for their captivating images and detailed product descriptions. They also provide customer reviews and ratings to build trust and pique visitor interest.

Key metrics to track in this stage:

  • Pageviews

  • Time spent on the website

  • Bounce rate

  • Email open and click-through rates

Conversion stage

This is when your prospective customers actually make purchase decisions. Offering competitive pricing, flexible payment options, free shipping, and a smooth checkout process can all play a significant role in the conversion funnel.

For example, ASOS offers a ‘Buy Now, Pay Later’ option to make it easier for customers to complete their purchase, reducing the financial burden on the customer and making the process easier.

Key metrics to monitor at the purchase stage:

  • Shopping cart abandonment rate

  • Conversion rate

  • Average order value

  • Cost per acquisition

Loyalty stage

After the sale, your task is to build customer loyalty and encourage repeat purchases. This can be achieved through excellent customer service, loyalty programs, personalized offers, and regular engagement through email newsletters or social media.

For instance, Starbucks’ loyalty program is a prime example of a successful customer retention strategy. They offer points for every purchase, which can be redeemed for free drinks and food, encouraging customers to come back.

Key metrics at this stage include:

  • Customer lifetime value (CLV)

  • Retention rate

  • Repeat purchase rate

  • Net promoter score (NPS)

Common challenges of eCommerce funnel optimization

While all this may look easy and straightforward, creating eCommerce growth funnels doesn’t come without its challenges:

  • Driving traffic: While techniques like SEO, PPC, and social media marketing can drive traffic, they require time, effort, and expertise to execute effectively.

  • Visitor engagement: Keeping visitors on your site long enough to pique their interest can be tricky. High-quality content and blog posts, intuitive navigation, and fast load times can help here.

  • Conversion: Turning interest into sales is a considerable challenge. Streamlining the checkout process, providing excellent product descriptions, offering competitive pricing, and displaying customer reviews can help improve conversions.

  • Shopping experience: A single glitch, slow load time, or complicated checkout process can result in cart abandonment, so ensuring a seamless user experience is vital.

  • Customer loyalty: Acquiring new customers is often more expensive than retaining existing ones, yet building customer loyalty can be difficult. Regular engagement, excellent customer service, and loyalty programs can be effective strategies here.

In each of these areas, it’s essential to continually test, measure, and optimize to ensure you’re meeting your customers’ needs and expectations. Take a look at our guide on eCommerce growth experiments to further improve your knowledge on this topic.

How to Measure Your eCommerce Funnel Performance

It’s great to know all the specific tactics, but how can you measure it all and know how to adjust your strategy over time? This is where the Noibu tool gets to shine.

The Summary Dashboard serves as the central hub, offering a succinct snapshot of your website’s health. It provides insights into the total revenue loss, significant issues, funnel steps affected, and the efforts of your team.

The Quick Stats panel is your starting point on the Summary Dashboard. It gives a quick overview of the annual revenue saved, the outstanding revenue loss, and any new issues identified within the selected time frame.

The Funnel Analysis chart complements the Quick Stats, displaying the Annualized Revenue Loss totals for each step in the marketing funnels during the chosen timeframe. It tracks the customer journey through four critical stages:


  1. When a customer lands on your site.

  2. When a customer adds a product to their cart.

  3. When a customer initiates the checkout process.

  4. When a customer finalizes their order.

The chart helps visualize potential revenue losses at each stage due to errors, aiding you in prioritizing your debugging efforts.

Key features of Noibu

Noibu’s platform offers features that showcase all errors affecting revenue and conversion. It pinpoints the funnel step affected and flags the common steps to reproduce the error. 

  • Session Replay: This feature allows an in-depth replay of the customer journey, negating the need for inbound customer tickets or reliance on insufficient details. It includes video replay and console information, simplifying the error reproduction process.

  • Developer Tab: The Developer Tab provides vital details needed for confident debugging. It offers stack trace, browser details, last steps, HTTP information, and more, allowing for faster and more effective issue reproduction.

  • Issue Management: This helps in planning and executing bug resolutions right within Noibu. It allows for ticket triage directly on the platform and syncs with Jira for convenience. With custom tags, organizing and managing issues becomes straightforward, and the sharing capability facilitates cooperation with external partners.

How to Improve Your eCommerce Growth Funnel Optimization

Implementing the mentioned tactics is necessary if your goal is immediate growth, but shaping strategic, long-term plans through a proactive approach will continuously improve your eCommerce growth funnel. Here are some advanced, big-picture tactics to consider.

Leverage data for personalized experiences

Utilize the power of eCommerce data to personalize your user experience at every touchpoint. You can personalize emails, product recommendations, content, offers, and more based on user behavior and preferences. 

One example would be to use something similar to “Customers who bought this also bought…” and “Frequently bought together” recommendations to drive additional sales.

Optimize for mobile

With the rise of mCommerce, a mobile-responsive design that loads quickly and provides a seamless browsing and shopping experience across different devices can significantly improve conversion rates.

Apart from providing a mobile-friendly site, consider building an intuitive app and offering features like visual search and social media integration to enhance the mobile shopping experience.

AI and machine learning

AI and machine learning can be leveraged to improve product recommendations, personalize customer experiences, automate customer service via chatbots, and predict future trends. They can help create a more seamless, efficient, and personalized experience for your customers, improving your conversion process and customer retention.

Fashion retailer Stitch Fix uses AI and machine learning to personalize clothing recommendations for customers based on their style, size, and price preferences, creating a unique, tailored shopping experience.

Scaling and Expanding the Funnel

Expanding your eCommerce growth funnel isn’t just about enlarging your customer base, but also about deepening the relationships with your existing customers. 

The following are some advanced tactics to help you scale and expand your funnel growth:

  • Diversify marketing channels: Consider exploring channels such as influencer marketing, podcast advertising, or even offline advertising like print or television, depending on your target audience.

  • Explore international markets: If your products have potential appeal outside your current geographic market, consider expanding internationally. Fashion retailer Zara is a great example. It operates in over 96 countries, adapting its product offerings and marketing strategies to local trends and cultures.

  • Enhance product range: This can attract new customer segments and encourage existing customers to make additional purchases. Be sure to conduct thorough market research to understand what new products your customers might be interested in.

  • Implement new technologies: Whether it’s AR technology to allow customers to ‘try on’ products virtually, AI chatbots to enhance customer service, or personalized video marketing, staying on the cutting edge of technology can provide a significant competitive advantage.

  • Optimize operations: As your funnel expands, you’ll also need to optimize your operations to handle the increased volume. This might involve enhancing your supply chain management, implementing automation in areas like customer service or inventory management, or improving your website’s hosting and load times to handle increased traffic.

Final Thoughts

While the tactics outlined in this article can provide a solid foundation, remember that no two businesses are exactly alike. The best strategies will always be those that align with your ultimate goals, target audience, and brand identity. Therefore, constant testing, iteration, and flexibility are critical to your sales funnel optimization efforts.

Keep in mind that technology has a significant role to play in this process, with platforms like Noibu providing comprehensive tools for measuring, analyzing, and optimizing your funnel growth and performance.


And finally, remember to maintain a big-picture perspective, focusing not only on immediate tactics but also on long-term strategic planning. Your eCommerce journey is what shapes you and your business, instilling resilience, agility, and an unerring focus on the customer – qualities that are the hallmark of every successful eCommerce venture.
