Usability Testing Toolkit: Resources, Articles, and Techniques
Usability is paramount in creating a good website or web app. If your site isn’t user-friendly, the majority of visitors won’t come back, regardless of how good your content is. You need to do everything in your power to make sure every website you design or web application you create is as user-friendly as it can be.
So how do you do that, exactly? The answer is simple: you test the site for usability. This involves getting actual users to try the site and let you know what isn’t working for them, either through automated means or simply by telling you. Read on for more information on usability testing and some tools available to help you.

Usability Testing Tools and Methods
There are tons of tools and methods out there to help you more effectively test usability on your sites and apps. Here are some of the best ones to get you started.
10-Second Website Usability Testing
While 10-Second Website Usability Testing might sound like a myth or something that wouldn’t actually be helpful, this technique really does give you a good idea of how user-friendly your website is. In short, it involves evaluating your site with all the styling information turned off.
WebSort.net is an excellent tool to use if you use the Card Sorting method for designing your site’s information architecture. It lets you conduct remote card sorting tests online. All you have to do is create a study and invite participants. The site takes care of the rest. A single study costs US$79, but you can also order a 5-pack (US$299) or subscribe to conduct unlimited studies (US$199/month).
Crazy Egg lets you create heat maps based on user clicks. It can give you insight into what visitors click on most often and what still needs to be improved to increase conversions and click-throughs. You can also view the raw data about where visitors are clicking, in addition to the heat maps. They have plans available that range from $9 to $99 per month, based on the number of visitors and pages you want to track.
Usabilla is a simple app for usability testing that can be set up in just five steps (create a test, select the pages you want to test, select your questions, invite users, and analyze the feedback you receive). You can test live pages or images, and it includes the ability to view click results as a heat map.
Silverback offers what they call “guerilla usability testing”. They allow you to capture and record screen activity, record a participant’s voice, export your videos to Quicktime, and control your recordings while conducting usability tests. It’s only compatible with Macs, but you can try it free for 30 days (the full license is less than US$50).
Userfly makes it very simple to test your website’s usability with your real website visitors. It records every mouse movement and click visitors to your website make and installs with only a single line of code. You can run up to ten captures per month with their free account (which also saves recordings for 30 days), or up to 10,000 per month with their Enterprise account, which is $200/month.
Fivesecondtest can help provide valuable feedback on which parts of your site designs are standing out to visitors. Basically, visitors have five seconds to click on the most prominent parts of your website, and then describe what it is the clicked on. The service is mostly free (there are some premium features, too) and doesn’t even require registration.
UserTesting.com facilitates your usability testing by taking care of pretty much everything for you. You get a Flash video of exactly what testers did and said as they browsed your site, as well as a written summary of what they liked, didn’t like, and what might have made them leave your site. The cost is $29/tester.
Infomaki is a tool developed by the New York Public Library for rapidly testing mutliple site designs and language without disruption to website visitors. It’s open source and can make large-scale usability testing much simpler.
Chalkmark lets you conduct testing on visitors’ first impressions of your site. To use it, you just set a task, upload an associated image, and invite participants. You can view results immediately, as they come in. The cost is US$109/month or US$559/year.
FeedbackArmy is a usability testing service that’s simple to use and inexpensive. It only takes a couple minutes to set up a usability test, and you get 10 reponses for US$10. It’s one of the more inexpensive options for gathering usability info, and can be customized more than many similar options.
Using screencasting software in usability testing makes a lot of sense. After all, one of the primary goals of usability testing is to find where users are getting hung up. By capturing everything that happens on their screen, you can better determine exactly what is slowing them down.
CamStudio is an open source screencasting software that works on Windows machines to capture everything you do on screen. Unlike many screencasting solutions, CamStudio is free.
Screencast-o-Matic is another free screencasting software that works within a browser, making it particularly well-suited to website usability testing where your users might not be centralized in one place.
If you’re really serious about screencasting (and will likely use software for more than just usability testing), Adobe Captivate might be the solution for you. It’s aimed at the educational market, so is probably overkill for many applications (especially since it’s nearly US$800), but it is an option.
For more screencasting options (there are plenty of them out there), check out Mashable’s 12 Screencasting Tools for Creating Video Tutorials or Wikipedia’s List of Screencasting Software.
