The meta tags or metadata provide information about relevant information of a web page. They can be found in the header area of an HTML document and are not visible to the user searching on search engines. Metadata can be recognized by a name and the respective content of the document. The information of the content of a document can be arbitrary. Information such as description of the content of a web page, title, author, important keywords and also meta tag robots, which are responsible for controlling the crawler during indexing.
The function of meta tags fell under the abuse of many website users. In order to bring the own page on a high ranking position a multiplicity of keywords were used, which had partially nothing to do with the contents of the web page. With the change of time and therefore technology, the meta data lost its importance and now it is no longer the descriptions of the respective meta data that determine the position of the ranking in the search results.
