Why is it advised to include publication dates when assessing website credibility?

Including publication dates when assessing website credibility is important because recent information can indicate relevancy. In many fields, especially those that evolve rapidly like science, technology, and current events, the most up-to-date resources contribute significantly to the reliability and accuracy of the information presented. When users can check when a webpage was published or last updated, they can determine if the content reflects the current understanding or advancements in that area. This helps to ensure that the information used for research or educational purposes is applicable to the present context and not outdated, which may lead to misunderstandings or the use of incorrect data.
