Optimization of the Great Courses site was done in two stages. The first stage focused on quick wins and going after low-hanging fruit to make tactical improvements to the experience based on discoveries made during the heuristic analysis. The second stage was a robust and complete site redesign.
The Great Courses is a series of college-level video and audio courses produced and distributed by The Teaching Company.
