When is it appropriate to link to external content?

Linking to external content is appropriate when it provides specific information that enhances the understanding of the topic at hand. This means that the external content adds value by offering additional details, context, or evidence that can help the reader gain a more comprehensive understanding. For instance, if an article on a knowledge base discusses a technical problem and includes a link to an authoritative source that breaks down the technical details or provides statistics, this can significantly enrich the user's experience and knowledge.

Choosing to link to specific information ensures that the resources being shared are relevant and beneficial to users. It emphasizes the importance of using external content strategically to support and validate the information being presented, rather than relying on general or unrelated content. This practice fosters trust and encourages users to seek out credible sources, ultimately leading to a more informed audience.

In contrast, linking to out-of-date content could mislead users and diminish the credibility of the information provided. Linking simply because a topic is popular or because the source is well-known does not ensure that the content is relevant or useful in the context of the user's needs. Therefore, the specificity and relevance of the information linked to is paramount in making useful contributions to the understanding of a topic.
