USER RESEARCH

Usability test tasks to avoid

Whether you’re carrying out your own test or a specialist is doing it for you, there are a few tasks I that recommend you avoid.

Free browse

It’s totally artificial. In a usability test you’re trying to simulate reality. You want to see how people are actually using your site out there in the real world. Nobody is going to just browse around your site without purpose. It’s tempting just to get their impressions of the site but it’s of no real value. If you start off with a free browse task you’re basically giving the user the opportunity to teach themselves how to use your site.

It’s a waste of your first task. There is naturally going to be some learning that takes place during a usability test. So your first task is the most real. It is the one that the participant attempts fresh. This is the moment when you get to see how people use your site when they’ve never used it before. If you use this opportunity to let participants have a quick browse around then you’re throwing away the most useful part of the session.

Homepage review

It too is artificial. Like the free browse task, the homepage review does not simulate reality. You can get a bit of useful information from it, but at the cost of making the rest of your tasks unreal.

You help the participant decide where to click. When people attempt to find information on a website they don’t look at every link on the homepage. They often follow the first appropriate looking link.

If you’ve previously walked them through every aspect of the site’s homepage you are giving them an insight that they will not get in reality. Instead of following the first link that looks appropriate, they can use the knowledge from the homepage review to decide which of all the options is the best. They are then performing a scenario that bares little resemblance to the experience real users will have.

Eyetracking the homepage

The results of just eyetracking participants looking at the homepage are totally useless without giving them a task to do. I’ll explain this with an example.

If I were to ask you to look at a door without any other instruction you would probably stare blankly at it. If you knew I was eyetracking, you might feel obliged to look around different bits of the door.

However if I were to ask you to open the door then you would most likely look at the door handle. If I were to ask you to remove the door, you’d probably look at the hinges. You see the areas you look at will depend on the task you are trying to complete.

It’s a totally useless exercise to just show a participant a page and then track their eyes while they do it. Nobody will ever visit your site to just stare blankly at the page. You might end up with a pretty picture to pass around the office. But that’s all it is, a pretty picture.

The results of eyetracking a page will differ widely depending on the task that the participants are asked to complete.
