Web Site Usability - what do you need to consider!

Web usability is all about taking a look at sites, pages and designs to better understand the customer journey - the reasons why visitors are there in the first place, understanding any barriers that stop visitors from taking their desired action.

In essence, your web site should provide your visitors with an efficient and enjoyable user experience.

Web pages should be self explanatory and obvious.

The MUM Test


When considering the basics for web page usability, I like to ask the following simple question 'Would my Mum be able to use it!'. You see my mum wasn't a tech head, she wasn't particularly well educated in these modern technologies, so she wasn't at all web savvy; and if we think of our potential visitors in this way then we will always ensure that our sites are a simple (and easy) to use as possible.

Basically, if my mum could navigate a web site and get what she wanted, then it was a good site.



Key Areas to consider

Intent - what are you visitors intending to do on your site?

Web site Structure (appearance) – what your visitors see and interact with.

Whitespace – clean space that makes your site easy to view, read, understand and use. Good use of space can draw the visitors eyes to the important parts (and links) of the site.

Noise – is information fighting for attention or does any other element vie for the visitors attention (strong contrasts next to text for example (i.e. bold graphics or images next to key information can force eyes away from this text)).

Length – short page length, visitors shouldn't have to scroll too far to get to the information that they want, information “below the fold” will not get seen as much as information above it.

Consistence – across navigation, fonts, layout, colour etc

Images – need to be relevant and compelling.

Functionality – how well the site interacts with visitors and visitors with the site.

Organisation of information – and links. Do users know where they are and where to get to the common information they might need? Can visitors get to the action you want them to take easily.  Are the web pages split into clearly defined areas.

Speed – how fast the site loads (< 2 second is ideal) as customers may leave if they have to wait to view the information on your site. Site speed is also important for good Google rankings.

Interactivity – how well can visitors interact with your site, does search work well for example?


Things visitors should never ask themselves

  • Where am I?
  • Where do I start?
  • Where did they put ….?
  • What information do I need on this page?
  • Why did they call it that?
  • Why is that there?


Common questions to ask

  • What is the first thing you notice on the site? Is your USP clearly visible?
  • Is there a clear visual hierarchy? (headers, important information etc) – newspapers do this REALLY well!
  • Are the pages consistent (everyone knows instictively how to read a newspaper and what the headlines mean, bold intro text, main story, caption under images, we know to go to the back pages for the sport and somewhere close to the middle for TV listings etc). Familiarity is reassuring.
  • Do you think it's too cluttered?
  • Are you having a hard time finding the information you want?
  • Does the site feel well organised?
  • Do you have to scroll to get to important information?
  • Is the site slow?
  • What do you think of the fonts, colours and images?
  • Can you easily search for product information?
  • Can you easily find the contact information?

The Search Engine Ranking factor

I've already mentioned that site speed is important for Google ranking, but also IF your site doesn't look very good to visitors they are likely to press the BACK button on their browser quickly.  This visitors action is classed as a Bounce by Google, and a high Bounce rate will go against you in rankings!
