My blog has thousands of external links to file hosting websites and now i am heard that these links cause decrease in page rank and i want to solve this problem but i have not enough time to edit every post and then edit every link and Add 'rel=nofollow' attribute to each link. I have searched for java script that automatically that do this automatically for all links i have found this <script src='http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js' type='text/javascript'/> <script type='text/javascript'> <![CDATA[ jQuery('a').each(function(){var a=jQuery(this).attr('href');if(typeof a!='undefined'&&a!=""&&(a.indexOf('http://')!=-1||a.indexOf('https://')!=-1)&&a.indexOf(window.location.hostname)==-1){jQuery(this).attr("rel","nofollow")}}); ]]> </script> But this not work for me. I have also installed seo quake plugin in my google chrome that highlights nonfollow links, this shows me that above script is not working. I need such a script that nonfollow all outlinks to my website If any one has solution then please tell me.
