Ultralingua conducted usability testing on their website to evaluate the efficacy of changes made during a redesign. They used two online tools - UserTesting and ClickDensity - to test tasks on both the original and new websites with 3-5 users each. Analysis found improvements in time spent on tasks and clicks with the new site, but also identified issues like confusing images and links. Recommendations included repositioning the 'Lost Registration Key' link and improving navigation of the Press page. The testing provided insights to guide further optimization.
