What UX & UI design lessons can we learn from Asda’s troubled website migration?

If you’re an avid online shopper at one of the UK’s top supermarkets, Asda, you may have something in common with one of Effect’s Account Managers, Sam Fox: you’re absolutely fuming with their new grocery order interface.  

Two weeks ago, Asda migrated from a sub-domain to a sub-directory - a feat that was no doubt hugely complex - and gave the interface a major facelift in the process. Sistrex recently wrote a great article that covers the massive impact this has had on their search visibility (spoiler: it is currently 12% down on visibility and has given up over 20 VI points to competitors), but what is the impact of these changes on existing, loyal customers?  

I sat down with the aforementioned Account Manager and devoted Asda shopper, Sam Fox, to learn more. She raised two key failures: 

  1. The search functionality no longer works effectively, meaning you just can’t find certain items.  

  2. The changes in the user journey for regular customers have made it difficult to order your recurring slot, and you can no longer add a prepopulated shopping list to your basket. 

 This has resulted in customers not being able to do the two key functions of the site: find the food they want, add it to the basket, and secure a regular delivery slot.  So, like, the whole point.  But they do now have a lovely little animated shopping basket whilst your payment goes through! Says Sam, ever the optimist!  All that got me thinking…we design brilliantly effective interfaces, often geared towards conversion, for many of our partners, including Way of Life, London City Airport, Panache Lingerie, Scott Bader, and more. What ‘brilliant basics’ do our UX & UI design experts, Sanjay and Paul, always implement when they approach a new project? And will utilising these allow us all to avoid a similar misstep? 

Lucky for me, they have two key guiding principles which form the basis of every project:  

1. Navigation is the beating heart of your website. Everything – user experience, journeys, satisfaction, and much more - stems from it. 

How users will use your site is largely up to how you allow them to. What journeys are customers likely to take through your site? What journeys do you want them to take? It’s imperative to keep those simple, straightforward, and easily navigable.  So, as a completely hypothetical example, if you were a major grocery retailer redesigning your site, you should start that process from navigation and then work your way out from there. Your most important journey on the site may be for a user to book a delivery slot and populate a shopping basket. If so, keep those at the top of the hierarchy, intuitively placed so they are easily found by all customers. When we approach a new project, one of our first steps is to document a written sitemap to map out the navigation hierarchy, including pages and page types, content requirements, and other structural notes. In some cases, we run a tree test to sense-check if users will be able to easily find what they’re looking for.  “What is a Tree Test?” I hear you cry! A tree test is a simple way to test a draft structure of the site. We’ll engage a test group representative of the different types of people that may engage with the website to user test the draft structure and navigation, asking our testers to find items in a stripped-back list of pages. We measure the success of our design based on the percentage of users who can successfully find the item, how directly they found it, and how long it took them to find it.  Even if a high percentage of users are eventually successful in finding an item, if they aren’t able to find it directly or quickly enough, it flags those potential friction points early on, allowing us to ensure that our labels and hierarchy make sense before we move on to designing the full interface.  

2. Use visual hierarchy to avoid design fatigue and aid in customer conversion – but one size does not fit all. 

Now that you know that users will be able to navigate your site with ease and find exactly what they’re looking for, you don’t want to trip at the final hurdle! Once a user navigates to a product page or searches for a specific item, your UI steps in to help seal the deal and convert customers.  

Visual hierarchy allows users to skim read through a page of products to easily find what they’re looking for and avoid overstimulating the user.  

What that hierarchy should be, however, will depend on what you’re selling.  

If you’re designing a hierarchy for a clothing brand, for example, the image is the first thing you’ll want to see. ‘Do I like this? Will it look good on me?’ 

Then the secondary tier is price – ‘How much does it cost?’  

Once those two stand out, the rest is tertiary – ‘What brand is it? Are there any reviews? Does it come in any other colours? Is it new?’

In our example here, our lovely model (aka Director at Effect, Natasha Riley) showcases this hierarchy beautifully: The image modelling the product is the largest component in this product card, followed by the price. Then, the additional components, including social proof (customer reviews), brand, sizing, colour options, etc, all appear subtly to further enhance the customer’s purchasing decision without overwhelming them. 

But you should approach a product card differently if you’re designing the UI for, say, a grocery retailer.  

For example, especially in the current economic climate, the first thing you’re probably looking at when doing your weekly online food shop is the price of a product, and then the price per measurement of that product. 

Then, if you’re unfamiliar with a product, you might look at the reviews to see if other people have enjoyed it.  

Then, the rest is tertiary - things like the brand name and whether the item is on sale (e.g. ‘Rollback’ or ‘Aldi Price matched’).

In this example, whilst the image is still a significant portion of the product card, the price takes much more of a front row seat compared to the clothing brand product card. Customer reviews also appear more prominent to aid in the customer’s perception of product value.  

Now trust me, we've really only scratched the surface of designing effective and intuitive UX & UI - but consider this your crash course. If you can get these two principles right, you’ll be on the path to building an impactful website that truly puts your customers first.
