Which of the following could suggest a webpage has not been updated recently?

The presence of references that are several years old serves as a strong indicator that a webpage may not have been updated recently. In many fields, especially those that rely on current data, trends, or technological advancements, outdated references can suggest that the content has not been reviewed or revised in a significant amount of time. Websites that aim to provide accurate and up-to-date information typically incorporate more recent sources, as this reflects a commitment to relevance and reliability.

In contrast, new articles and blog posts, frequent visitor engagement, and a recent publication date would all suggest that the site is actively maintained and updated. Therefore, if a webpage primarily relies on older references, it indicates a potential lack of recent updates.
