In the context of the digital environment, e-commerce platforms emerge as mediators in a variety of interactions and transactions among users, sellers, and service providers. Nowadays e-commerce systems are, perhaps, the most important in all the world. Most people and businesses in the world make their purchases and transactions through these kind systems, hence its usability is, if possible, even more important. This study focuses on formulating and developing specific evaluation heuristics for e-commerce platforms, integrating concepts from Collaboration Engineering, Quiñones and Rusu's methodology, and Granollers’ methodology. The combination of these methodologies aims to address the complexities of e-commerce platforms, strengthening evaluation heuristics to enhance the quality of digital experiences. A new version of the heuristics is proposed, based on Granollers’ methodology, consisting of a single heuristic with 8 characteristics, each with a series of questions to assess the usability of e-commerce websites. This research aims to optimize interactions and increase the effectiveness of these platforms in the digital environment.
