This document outlines the ABCD method for evaluating websites. It examines the Analysis of the URL, Authorship, potential Bias, Content, and Date of a website. The ABCD method provides criteria to determine if a site should be used or questioned for a research purpose. Key factors include determining if the author and organization are experts, if the information is accurate and consistent with other sources, and if the content is current and recently updated. Using the ABCD method can help evaluate whether a website is reliable and appropriate to use for academic work or if it should be avoided.
