Fast Food Usability Series: Burger King Case Study

Marc Madjaric by Marc Madjaric

In This Series: Studying the Usability of Fast Food Ordering

  1. Fast Food Usability Series: Wendy's Case Study
  2. Fast Food Usability Series: Burger King Case Study

We visited fast food restaurants to test how real-life users experience ordering through their websites.

This is part two of our multi-part series on usability issues with fast food eCommerce websites. In each part, we’ll highlight the usability problems (and possibly some successes) we discovered through performing guerrilla user testing(1) at popular fast food restaurant locations.

We’ll also offer suggestions on improving each website for higher conversions and customer satisfaction. 

Restaurants have some of the highest conversion rates in the industry(2), complex menus with lots of options, bundling, and pricing configurations. This series teaches you about fast food’s successes and failures. Let’s get started!

Case Study: Burger King

In this part of our series, we're studying how users order at http://bk.com. By testing and evaluating how users navigate the site, we will discuss some of the biggest problems and show some suggestions on how we would solve each issue.

Usability Issue: Button Position 

The first usability issue is the “Share Location” button, which is placed at the bottom of the homepage.

When the page is opened on a small screen, the “Share Location” button is hidden. Making matters worse, having the button located so far away from the store finding components creates confusion and makes it harder to locate.

Solution: Better Placement 

Allowing users to quickly find the closest store location speeds up the ordering process and lessens site abandonment. We can find one solution on the Five Guys site, which has a component that allows users to search using their current location. When a user clicks the “Use My Location” button, the closest locations are displayed below. They also highlight the nearest location, speeding up the ordering process and raising conversions.

On the Burger King site, we would solve the “Use My Location” button issue by moving the “Share Location” button next to the “Your Location” text box. The principal of placing related items closer to each other is related to the Law of Proximity(3) from Gestalt psychology.

Usability Issue: Required Sign In

Another usability issue is blocking users from completing their purchases by requiring them to Sign In. Currently, Burger King forces users to Sign In with a validated email by creating an account before allowing them to payThe Sign In multi-step process slows ordering by adding friction, leading to cart abandonment rates that often lie between 68% and 75%(4)

It takes over one minute to complete the steps required to Sign In.

Solution: Remove Extra Steps

KFC’s site shows an excellent competitive example of how to solve the issue. They remove the Sign In and registration processes, which allows users to checkout in one step.

By removing the extra steps, Burger King would allow users to complete the ordering process and pay without abandoning their transactions.

Interrupting a user before they have completed ordering slows the process, which prevents a quick checkout. Registrations involve extra steps and potential problems for things going wrong. There is a direct connection between user hassle and lost sales(5)

Usability Issue: Only Credit Cards Allowed 

Users can only pay by credit card on the Burger King site. This issue creates user frustration for anyone with other payment services set up on their phone. Burger King slows the ordering process and lowers conversions by limiting payment options.

Solution: Add EasyPay

A good solution would be adding other payment options such as Google pay, Apple Pay, and PayPal. Since 2020 mobile payments have increased by 27.9% from $1.54 trillion. According to projections(6), the market will continue growing at 29.1% annually over the next seven years, eventually reaching $11.83 trillion by 2028. Limiting users’ payment options, Burger King creates an opportunity for other services that users may find quicker and easier to use.

By removing these remaining obstacles from the users’ ordering journey, Burger King will speed up the checkout process and create a more seamless experience. Creating a positive ordering experience(7) will give users a strong impression long after leaving the site. 

 

🥳 Usability Success: Customization

Burger King has one excellent example of successful usability: its product customization.

By keeping the interface simple and consistent, users can process orders quickly with less confusion. This site makes complex choices straightforward by utilizing the UX Principal of Visual Hierarchy(8), labeling and grouping complex options for the user.

This area of the Burger Kings site is an excellent example of how UX design and visual-design principles(9) can improve customer satisfaction for a fast food eCommerce site.

🤔 Usability Issue Example: Forced Options

On Chipotle, when a user selects a product, they must pick all available options or select the no option for each section. Users must scroll through a long list of possible choices. Not having default options pre-populated will slow the ordering process and lower conversions.

Conclusion

We discussed three ways that Burger King could improve its site:

  • Improve the placement of the “Share Location” button at the bottom of the page, which is hidden on smaller screens.
  • Remove the process requiring the user to Sign In before purchasing.
  • Accept forms of digital payments that are easy to use: Apple Pay, Google Pay, etc.
From our experience implementing comparable changes, we believe conversions would go up 4% just by making the three suggested changes. Making comprehensive, research-backed product design improvements, we have doubled conversions for similar retail clients.

Look out for our next post, where we will guerrilla test another fast food eCommerce restaurant website. We tackled similar problems in the previous post, Wendy’s usability issues
