The article outlines the issues of website quality assessment, reduction of website assessment criteria and factors that users employ in the assessment of websites. The article presents a selection procedure concerning significant choice criteria and revealing undisclosed user preferences based on news portals and the eQual assessment model. The formulated procedure utilizes statistical metrics, multiple criteria decision making, rough sets and data mining tools. Results concerning undisclosed preferences were verified through a comparison to those declared by website users. The obtained results were further verified through a comparison of website assessments obtained via a full and reduced set of website assessment criteria.
