These sections are traditionally used to provide additional or supplementary information, but they often duplicate content. Including these sections in online articles makes the pages longer and increases the amount of scrolling for users.

If the information in your annex or appendix is available on another page, use clearly written hyperlinks to link to the page instead of duplicating the information. If the appendix is lengthy and contains additional analysis or data, consider publishing it as a separate article that can be linked to from the article.
