Robots.txt instructions

Robots.txt is one of the special files found in the root directory of any web resource. It contains certain directives regarding access to certain sections of the portal. Robots.txt is also commonly referred to as the “search bot exceptions policy”.

Using the functional features of the file allows the professionals to close for indexing those pages that he does not consider necessary to index. In addition, it is in robots that the address of the map and the addresses of the website mirrors are usually set.
