    Ban all unnecessary urls:

    //Запретить урлы содержащие ordering= в урл Disallow: *ordering=* //Запретить урлы содержащие orderto= в урл Disallow: *orderto=*

    Well, and so on

      Use the design:

       Disallow: /*?ordering=*&orderto=*

      or

       Disallow: /*.html?ordering=*&orderto=*
