Pessimization - lowering the site’s position in the search engine results (artificially reducing the relevance of the request). It is superimposed on the sites by the administrators of search engines or automatically based on the identification of dishonest methods of "promotion" on a pessimized site. This is usually the presence of non-unique content on the site and a quick set of unnatural links, as well as aggressive advertising, viruses in the code, and more. Using pessimization, search engines strive to make their search results more useful and relevant to the user's search query.
