With conversion rates in the e-commerce space hovering around 3-5% globally, CRO can be a distinction maker, especially at scale.

Having an online platform through GoldenArchesUnlimited.com, McDonald’s enables its company to preserve a long-lasting relationship with its loyal buyers by igniting a modernized way of meeting its brand’s fanatics and products in one place.

2. Walmart.ca 

In 1994, Walmart.ca already started flourishing in the business. Now, it has one of the largest employers and numerous subsidiaries and distribution centers. They continuously grow in the industry as they unfolded contactless pay, home delivery services, online shopping, and others. But one fantastic thing that happened to Walmart.ca was their responsive redesign boost conversions that spiked up to 20%. It took them almost a year to make a responsive site and improve revenue through mobile devices. 

Based on their research, the general look of their site on mobile was dreadful and required a lot of time to load. From here, they started working on speeding up the overall experience and making it responsive to the screen size or device it was being used on. 

Walmart performed hands-on usability tests on its old, and new designs ran A/B tests on different website features and made general speed improvements. Finally, Walmart saw a 20% increase in conversions across all devices as an outcome of their new design. On mobile, orders rose by 98%, which is a good number.

After eradicating the “View Details” option from products that cannot be purchased online, they noticed an increase in conversions.

How fun is it to know that even a simple action can take you to greater heights, right? So, better start exploiting your website, do some research, and stay curious about what can transpire for your business! 

3. Isadora Agency

Through the years, Isadora Agency has already built a name as one of the top companies for eCommerce Digital marketing Agency.

They collaborate with American personal transporter manufacturer Razor as part of their craft. They discovered that there weren’t many reasons for users to visit the website because it lacked all the features required by an eCommerce website to facilitate direct sales.

Isadora accordingly made all the alterations after conducting in-depth research and analysis of the circumstance. The new product page ultimately served as the center of attention for Razor’s revamped eCommerce website. Visitors can now easily find any information on the website thanks to these solutions. Isadora has improved the user experience since the website’s inception through analytics reviews, A/B testing, and website upgrades.

This brief case study only tells you to try working with other companies and acknowledging that getting help is not bad. Besides, thorough research, maintaining strong ties, and conducting different methodologies for your consumers are just as important as your goals. So, balance them and ace the eCommerce game. 

4. BliVakker.no

Even though this case study is a little dated, it is generally accepted that streamlining the checkout process can improve conversion rates and advance income.

Given that everyone has a Facebook account and that Facebook is frequently linked to it, why not use Facebook Login to make the checkout process simpler?

BliVakker.no, one of Norway’s most prominent online cosmetics retailers, has been receiving 20,000 daily visitors. They sought to enhance their checkout process by making changes based on the findings of usability testing, well-known best practices, several A/B tests, and analytics data.

In one of these tests, they applied Facebook Login to checkout pages. Here, 8000 visitors were used to test the website using Visual Website Optimized. As a result, a 3% boost in conversions on the checkout page without Facebook equated to an additional $10,000 in weekly income.

We can learn from here that even though BliVakker adhered to accepted practices and conventional thinking, they erred by assuming that Facebook Login would increase conversions. Best practices by themselves fall short. Similarly, never, ever, ever allow the outcomes of a third party’s analysis to dictate how you should adjust your page. Always do your testing. 

5. Heineken 

Heineken N.V., a Dutch brewing company, launched Heineken Lager Beer, famously known as Heineken. It is a product with 5% alcohol by volume pale lager beer that comes in a green bottle with a red star. The brand has aspired to attract more customers and create different campaign materials over the years. 

With this in mind, Heineken thought of the UEFA Champions League as a marketing tool to draw in new internet visitors and consumers. They also ventured into engaging customers who only use digital devices after finding that most of their clients are UEFA Champions League viewers.

To reach this online audience, they carried out a Drinkies direct-to-consumer operation in Amsterdam. Within 60 minutes of placing an order, clients may receive cold beer and snacks at their doors. Huge thanks to the development of an eCommerce channel. The number of Drinkies remarkably rose on match days during the 2019 spring UEFA Champions League knockout phase. Correspondingly, they increased sales, and data showed a growth in the number of new Drinkies customers.

This Heineken eCommerce case study proves how their sponsorship of the UEFA Champions League allowed them to align with new customers and foster overall penetration. As a brand or startup business, you might want to combine direct-to-consumer operations with transparent marketing for your eCommerce campaigns to be successful. There are different ways to do this, but always remember to arrange everything in line with your brand. 

6. Taloon.com


The Finland-based online hardware retailer, Taloon.com, provides supplies for plumbing, electrical, gardening, and other building projects. They use the VWO platform to handle its website optimization requirements. Eventually, they opted for testing because they wanted to boost sales on their product pages.

 Contrary to popular belief, Taloon.com examined two product pages—one with social buttons and the other without—to see any discernible difference. Surprisingly, the competitor, often known as the page without sharing buttons, saw an 11.9% conversion boost. 

The key takeaway from this conversion rate optimization case study is that do not be afraid to take risks and discover new things, even if you go against the standard approaches. Including social sharing icons on your website typically increases traffic and conversion rates. But this study tells a different story. So, go and explore; perhaps you are the next one to uncover out-of-the-ordinary strategies.

Domino’s hired programmers and digital marketers to present lunch delivery to the IT world to sustain and develop this. Since then, they have advanced into an eCommerce company that sells pizza all over the globe.

8. Coca-Cola

For business development in 2020, everything revolves around COVID-19, including brand advertisements and how they behave in these darkest times. Lockdowns have sparked a digital shopping boom as consumers started looking for safety measures without interacting with products or people. As a result, eCommerce has become increasingly significant. 

At this moment, Coca-Cola is also prioritizing packaging choices that are appropriate for online sales, boosting in-app exposure with e-delivery, and testing out fulfillment methods that are supported by technology. In response, Coca-cola launched the MyCoke System, a more convenient way of ordering and shopping for consumers. As a result of this choice, Coca-Cola is growing its online businesses, such as Coca-Cola En Tu Hogar, which enables customers to order beverages and groceries for home delivery.

Consequently, customers may shop, buy, and track orders for Coke Catalog products easily. Thanks to MyCoke’s efficiency, it brings tons of advantages for Coke loyalists. Here, Coca-cola attests to the power of innovation and the purpose of technology during these trying times. It is harder for people to go outside due to the threats of the virus. That’s why they initiated a modern way of connecting with them without sacrificing their well-established brand.

You can always learn something from Coca-cola or other more prominent companies that have been standing here in the industry for decades. You can get ideas from reading their creative briefs, watching their ads, and understanding their case studies like this. 

9. SmartWool


Peter and Patty Duke, ski instructors from New England, founded the American brand Smartwool in 1994. From there, the brand constantly makes a mark in the industry and gathers more consumers behind them. 

Now, SmartWool is online and wants to increase its eCommerce revenues. Hence, they contacted Blue Acorn for assistance in increasing conversions. And here is their problem: Experienced conversion optimizers can improve a poor site’s performance substantially, but what if your customer already has a well-designed site that adheres to all best practices?

Luckily, the SmartWool team was open to testing various page layouts and the like to see which ones worked the best. One of the initial pages to be assessed was the category page. Its high traffic volume accelerated the process of receiving test results. 

With this, the Blue Acorn team created a brand-new, attractive design that was original and distinct. They tested their novel design against a tried-and-true alternative that uses repeating images arranged in rows of equal-sized images to enhance eye tracking when browsing merchandise. Eventually, they used Optimizely to build up the test and get the results. The findings show that: with a statistical confidence of 95% and 25,000 visitors tested, the variation—the more conventional category page—won by rising revenue per user by 17.1% compared to the baseline.

In this conversion rate optimization case study, you can infer that product images with bigger sizes can garner more clicks but do not give assurance for more purchases. Therefore, you should always run tests and use different analytical tools because it is paramount for your eCommerce objectives. 

10. Adidas

Most people know that Adidas, or Adidas AG, is a German manufacturer of special sports footwear and sporting goods. Despite thriving in the industry for years, the global health crisis affected Adidas’ business plans. 

In 2020, Adidas expected its online sales to reach $4.3 billion, a 55% eCommerce sales increase. And given the risks of the pandemic, Adidas efficiently invests in the digital realm. They have been attempting to digitally engage its clients in North America as its strategically targeted market.
