““Two primary points of abuse are the use of the meta fields in websites and extraneous links. Meta fields were originally designed to provide a way for site operators to add some keywords to their sites that did not need to be displayed to users, but might be useful to search engines. A site might use meta fields to give some synonyms for their content or to elaborate ideas that might be taken for granted by readers. For example, a website mentioning Brooklyn many times, but not New York City, might decide to add New York as a meta tag. However, some site operators put words in meta fields that have nothing to do with their content (the most common such word being sex since a great many Internet searches are from people looking for pornography).””
