User Interface Audit

Client:

Bramwell Brown, British clockmaker and e-commerce retailer

Role:

Undertake a site-wide audit of the UI and liaise with the developer to address lowest hanging fruit in terms of visual inconsistencies and UX issues. Create a Style Guide to help maintain consistency in the future.

Result:

Although not all of the changes are measurable, adjustments to the Homepage led to a 22% increase in CTR to the Product Page, and changes to the Contact Us page have led to a decrease in page Bounce Rate of 65%. Although relatively small numbers, these can be taken as good signs that the changes have had a positive impact.

Process & Findings

In hindsight, the thorough approach would have been to find a recognised audit template to work through and identify issues. However, in this case, I simply followed my instinct to uncover UX issues and inconsistencies, based on my knowledge of design fundamentals. I methodically worked through each page assessing aspects such as hierarchy, readability, recognition and accessibility.

Typography

One of the standout problems that the website had was with its inconsistence use of typography.

What were the problems?

  • Hierarchy - on several pages, the visual hierarchy was being severely undermined by the range of font sizes and colours. Hierarchy is key to guiding the user through the page, highlighting important messages and buttons.

  • Readability - in some cases, readability was reduced by the use of uppercase styles and unusual letter spacing.

  • Branding - from a branding perspective, maintaining consistent use of typeface for product names is important and was not being followed.

  • Recognition - a key tenet in usability is recognition, and text links have an accepted standard appearance - coloured blue and underlined - which was not being followed. This can interrupt a user’s flow if they do not recognise the text as a link.

In the examples above, you can see that by increasing contrast and adjusting font sizes, the pages have become significantly clearer to read, as well as having a better balance and hierarchy.

For the landing page, the decision was also taken to move the USP icons below the products. This was so that the primary desired action for the page - viewing the product - was seen by the user earlier, particularly on mobile.

Since implementing this, CTR from the homepage to the Weather Clock landing page has increased 22%.

The text links in the second example are also much more recognisable than before, but numbers are currently too low to measure an effect.

Accessibility

An important area that I discovered the business hadn’t been factoring into the existing design was accessibility. Among the four principles of accessibility as defined by WCAG - content should be Perceivable, Operable, Understandable and Robust - there are many different guidelines, and this is an ongoing task to improve the site with these in mind.

What problems have already been corrected?

  • Contrast - one of the lowest hurdles is making sure text and buttons have a contrast ratio of at least 4.5:1 for normal text, and 3:1 for large text - this is to earn a score of AA. There were a number of places that the site fell short of these and needed correcting, and examples can be seen in the previous section.

What else is currently being looked at?

  • Site-wide HTML - ensuring all page sections and elements are labelled correctly within the HTML to ensure that those browsing the site with page readers etc are able to browse easily.

  • Non-text content - we’re looking at updating all videos and audio to include captions or descriptions so that the media is not a barrier to accessibility.

  • Keyboard navigation - checking that navigation with a keyboard is logical and easy, including ensuring there are no keyboard traps and hover-state elements are triggered by selection with the tab key.

Buttons & Icons

Looking across the whole site, there were a number of other small user experience issues that I identified and corrected. These included:

  • Contact Us page

    In the screenshot below, the Contact Us page has been reworked to present the options on clickable cards, instead of icons with 6 “Click Here” buttons. This simplifies the decisions for the user. ✅ This is proven by a decrease in Bounce Rate of 65% (from 41% to 14%) since implementation vs the 60 days prior.

  • CTA colour consistency

    Maintaining a consistent colour for call to actions is important for reliably directing the user towards the main desired actions on a page. On the product page, the main CTA - Add to Cart - was black, and the usual blue colour was being used for an info banner, which wasn’t a button.

  • Interactive elements usability

    In some areas, such as scrolling through a carousel of reviews, there were no directional arrows, and the clickable area for the toggles were extremely small. Arrows were therefore added, and clickable areas increased to 44x44px to be in line with WCAG guidelines.

Style Guide

In order to help the business maintain its visual consistency and branding going forward, I have started a small style guide that specifies the use of typography, colour, buttons & accessibility goals.
