Optimising or delivering mobile UX?

As I was choosing which usability test clips (we ran 120 usability testing sessions) to share in this post I was reminded of a video that Google posted a few years ago that drew a parallel between the online and offline checkout experience.

Its purpose, I think, was to help retailers ‘humanise’ some of the problems that Google Analytics was reporting.

The video, in case you skipped it, shows a customer at a supermarket checkout struggling with the assistant who characterises a slow online checkout with a bad UX.

The video conveys, in a compelling and funny way a simple truth: people will leave a website if it’s too difficult to buy.

But, isn’t that obvious? Surely nobody would purposefully design a slow/poor checkout experience (unless RyanAir could make a swift pound from upgrading you to the fast/good one)?

Why, as digital professionals, do we need a video to show us this? 

I started asking myself similar questions as I was choosing which video clips to include in this post:   

  • Why can’t smartphone users zoom in to see what they’re buying?
  • How come search is so difficult?
  • Has anyone actually tried to get to, let alone click on, a link in the footer?
  • Don’t these leading UK retailers know of these problems?

Perhaps they do. And perhaps as they incrementally improve their sites these issues will be addressed (since websites are, of course, never finished),

Or are we too early in the lifecycle of mobile commerce for retailers to concern themselves with optimising UX?

It may be, as was recently explained to me by an ecommerce manager, enough that there is sales growth: “we’ll worry about optimising as the growth plateaus”.

As you consider the five key insights I’m sharing from the report, please think about your own organisation’s attitude to mobile UX. Where are you on the continuum of merely delivering (at one end) to optimising (at the other) mobile UX. 

How we did it

The research was conducted in January 2014 using the WhatUsersDo platform and jointly published with Practicology.

Smartphone users were set common shopping tasks (such as find a product, add to bag, checkout, look for returns information) across 15 high profile UK retailer sites.

These sites included Amazon, Argos, ASOS, Currys, Debenhams, House of Fraser, Fat Face, Goldsmiths, Ikea, John Lewis, Marks & Spencer, New Look, Ted Baker, TopShop and Very.

Insight one: search usability

We found that many smartphone users shared the same expectations of site search, and that for some retailer sites (particularly Fat Face and TopShop) their experience of search was particularly poor.

We found:

  • Users expect type-ahead functionality on search fields.
  • Users expect to use search for both finding products and other on-site information e.g. returns, contact us.
  • Almost no users changed the way that the results of their search were displayed (such as switching from product image to product detail views). 

In this clip you can see one user struggling to even find the search box on TopMan. He eventually gets there after two minutes. 


Insight two: product image zooming

All users expected to zoom in on product images and we observed some particularly easy to use interactions (most notably on the Very site).

However, three sites were severely lacking and either did not support pinch and zoom or only provided a single product image. For fashion sites in particular surely this is a dead-cert conversion killer?

Who would buy a pair of shoes if you can’t really see them up close (see clip below)? 

Insight three: adding to basket

 There was a lot of user confusion when it came to adding an item to a basket (or shopping bag) with many users adding the same item more than once because they did not receive interaction feedback in a timely manner.

In the example below we can see one user becoming increasingly frustrated with the Fat Face add to bag (as they are forced to choose a colour swatch even when there is only one colour):


Insight four: omnichannel strategy vs real life contact us experience

When you work in usability there are times when it is best to shut up and listen to the users.

The following clip (where a user is working out how to phone John Lewis) is one of those times. 


Insight five: finding returns information 

We set users a task of locating the Returns Policy on each of the sites, since insight from other tests indicates that this is important for conversions.

As well as using the on-site search, users looked in both the main menu and then the footer for the Returns Policy.

We found that most sites did not provide a direct link and that returns was ‘hidden away’ in Help or Customer Services with some providing desktop only versions.

In the clip below we can see just how hard it is for this user to find returns information on the ASOS site.


What it all means

The table below outlines how well the 15 sites performed against the 11 different categories of interaction that users tested.

Mobile Usability Report

Nearly all of the sites have some way to go to optimise the smartphone experience for their users. Even Amazon performed poorly when it came to navigation and add to bag interaction.

However, there were many examples of emerging best practice, in particular the Argos and Currys’ sites performed particularly well (until Currys presented shoppers with a desktop checkout version).
