cross linking
Cross linkings are cross links between the different web pages of a domain. Cross-liking is part of the linking structure of a website and is preferably used for extensive document collections and reference works.
Cross links take the visitors of a website thematically to another website. They correspond to cross-references in print encyclopedias and, if used properly, are used in search engine optimization to improve the ranking.
If cross-linking takes place from one web page to another and back again to the original page, i.e. if the web pages link to each other, this is referred to as a closed loop. Closed loops are evaluated negatively by search engines.
