How to make no follow links
in normal condition it is
as we click on post list tile it goes to post detail page
and when click on the title of post detail page it goes to the original site in the same windows and leave our site.
my basic question is this that is here any way or plugin so that when a visitor click on title in post detail page it will be as no follow link and also open in new windows so that visitor can view the original site and also do not leave my site.
