What are the admission requirements? What courses are available this semester? How much exactly does it cost to attend? Where do I park for the football game? University websites are the information hubs for prospective and current students, parents, and faculty, who usually come to the site with a specific goal in mind. With such diverse audiences, these websites need to be accessible enough for

Usability tests don’t have to be expensive or require a lot of technology. The real value is not in the equipment or technology but in the technique. Usability testing is not a focus group.

Unmoderated testing platforms allow for quick data collection from large sample sizes. This has enabled researchers to answer questions that were previously difficult or cost prohibitive to answer with traditional lab-based testing. But is the data collected in unmoderated studies, both behavioral and attitudinal, comparable to what you get from a more traditional lab setup? Comparing Metrics There are several ways to compare the agreement or

Small differences in design changes can have large consequences on website purchases. But detecting these small differences (e.g. 2%–10% changes) through behaviors and attitudes has generally not been feasible from traditional lab-based testing due to the time and costs of recruiting and facilitator costs/time. With unmoderated testing, organizations can now collect data from hundreds to thousands of participants quickly and from around the world to

In Benchmarking the User Experience, I write about the importance of a regular plan for quantifying the user experience of your websites, apps, or devices. This involves collecting metrics, usually at both task and study levels. But the point of benchmarking isn’t just to collect metrics to put on a dashboard, it’s to ultimately improve them.

For example, on a 5-point scale, such as the one shown in Figure
