I have done shedloads of website usability in my time. Some projects are straghtforward, others are very complicated. This is my guide to thinking about your own assessment – you might still need to do user testing, but this should start to surface the glaring problems.
1. Define your website’s goals
Your goals may be many and varied. List them all out before you start.
- Enabling people to do their banking online
- Informing prospective students about evening classes
- Persuading visitors to come to your gallery
- Providing up-to-date information about genetics research
- Helping people find out about your company
- Selling clothes/books/DVDs
- Showing site visitors that you are cool and happening
Brainstorm them, and then group them roughly into the hard goals (the concrete things that you want people to do next, like order something or make a call, or bookmark the page); and the soft goals, like the image or values that you want to convey.
You might want to put them in rough order of importance. Even now, you may be able to able to spot some obvious flaws. ‘We want people to sign up for our newsletter, but we’ve buried the link in tiny print at the foot of the page.’
2. Think about the typical website visitor’s journey through your site
This is usually called ‘the user journey.’ There will be a number of these. Some of them will be very important to you, others might be less important or less obvious.
So. What do people do here? What different journeys can you identify? Here are some to get you started.
- Browsing for information (about products/costs/opening times)
- Choosing something, or making a shortlist
- Downloading a report
- Buying or booking
- Ordering a prospectus
- (Often forgotten) Looking up your postal address
- (Often forgotten) Finding travel instructions before a meeting
Also think about the difference between the journeys taken by the first-time visitor and the returning visitor.
3. Check out your website’s performance on the basics
If the basics don’t work, you can forget about everything else.
Navigation (menus, tabs, headers, footers, links)
- Can your visitors find their way easily around the site?
- Does your navigation look like the navigation on most websites? (Hint: Horizontal scrolling is unusual)?
- Can they find their way back to the Home page? Even if they don’t know about the convention of the header doubling as Home link?
Navigation is often a real problem for visitors. It can also be the hardest for site owners to understand, because they know where everything is.
- Does everything work? (links, downloads, video)
- Does it work across all the important browsers/platforms?
- Does it work quickly? If it works slowly, does the process keep the user informed?
- If it doesn’t work, does it degrade gracefully? (Hint: Have a look at your 404 page)
- Is the language clear and appropriate to your users?
- Are your instructions friendly or nasty? (Hint: Fill in your forms and leave out some of the fields. How do you feel about the error messages?)
- Is the text easy to read (reasonable size, good contrast, pleasant background colours)?
- Is text size adjustable?
- Do the colours, layout and images reflect the message you want to send to visitors?
- Does it look…designer, professional, ordinary, folksy, edgy, homemade…?
- Is that what you’re aiming for?
4. Assess how you are doing with the main user journeys
You can score them if you like. Nothing complicated: excellent, room for improvement, poor, entirely missing.
Focus in particular on what your visitors do when they come to look around, and then what happens when they take action.
5. Look back at your master goals list
You should have enough information by now to understand whether you are meeting some of those goals. You may find that some are easily ticked off as excellent or circled as having problems that need solving. However, there will be a few left where you don’t have enough information to proceed. You may not know how real users view the site (in which case you need to get some feedback from real people), or you may feel that the basics are in place but the site is underperforming. Now you need to start the hard thinking about how to improve the website design so that you meet your goals.
In Part 2 (up early next week) I’ll run through my process on solving the thorny areas where the site is clearly underperforming.
