Comparative analysis of web and mobile interfaces of popular sales portals

Sales platforms are becoming increasingly popular, with a steadily growing user base. This article presents the results of a comparative study of the web and mobile interfaces of two popular sales platforms, OLX and Vinted, focusing on user efficiency and intuitiveness. The analysis entails measuring task completion times and evaluating the usability of both interface types on each platform using the System Usability Scale. The findings indicate that Vinted’s interface is more intuitive and faster for users who had no prior experience with OLX or Vinted.
