The document provides guidelines for when citations are required in articles. It states that citations are needed to support any numbers, statistics, or hard-to-find information. Citations allow editors to quickly fact check and ensure accurate information is being published under a client's name. Information is considered "easy to verify" if it can be found quickly through a basic search. Direct quotes also require citations along with a link to the source. Common knowledge facts and recommendations do not typically require citations. Links should only be included to provide extra context, not as a requirement to understand the article. Product pages, images, videos, or search results are not accepted as citations.
