There really isn’t a standard list because each site tends to have slightly different features. Generally, though, there are three main areas that should be tested:
(A) Technical (do the features work correctly?)
(B) Usability (is the site easy to use?)
(C) Accessibility (can visitors access the site’s content without too much trouble?)
Here’s a common list of technical things to check that would apply to most of our clients’ site:
- Does the site display on different browsers and operating systems? (Which browsers depend on your target market but usually they’d be Internet Explorer 7, 8 & 9, Firefox 11 & 12, Safari 5, Chrome 18. Operating systems for the general market would be Windows and Mac. We don’t usually consider mobile access unless it’s a feature that clients specifically request.)
- Are there any broken links?
- Are all the pages formatted so that all content is visible?
- Does the search facility turn up the correct results?
- Can you click through to the content images and do they expand and close to return you to the article?
As you can see, this is all pretty basic stuff because most of our site’s features aren’t too complex.
Because of this, I suggest that your user testing should mostly be focusing on non-technical aspects like (B) and (C). However, because the bulk of these areas are subjective, it’s difficult to come up with an actual list. Therefore, I would suggest having free form comment boxes for people to leave their feedback.
Another thing to note is that the UK and EU have legislation covering web accessibility. You can find out more about this via the following links:
Unfortunately, this topic is quite a complex and time consuming area and most companies and web developers know little about the subject. There are also doubts about how these laws can actually be enforced. Furthermore, there are no specific definitions on what exact standards must be met within the UK. Thus it is my experience that many web owners and developers simply ignore the issue.
My policy is that we use web-standards compliant technologies where possible. This resolves most accessibility issues within reason for the amount invested in development. However, if a client wants to meet specific standards compliance, we do this under our standard hourly rate as an added service.
Ultimately, this is a business decision to be made on the client end whether this should be a focus.
