I would like to change some link structure one of my wordpress webiste's posts about 10 those links has indexed for a year you know if I change the links google will try to index old links and it would not be nice for my website google can give to my website negatif rank anyway what can I do ? should I write rule in the .htaccess file to redirect new links ? or leave as it is ?
Redirect [301] old URLs to the new ones. This will transfer PR/Link-Juice from old pages to the new ones and will avoid duplicate content issue.
Thanks is there any configuration section on google webmaster tools to redirect each link to new one(I couldn't see it) or Do I have to do that with .htaccess file ?
