Hiding links from Google?

Say I don't want Google to follow my links, or even notice them as links, will 开发者_如何学Pythonsimply replacing the a href with an onclick location suffice?

Does Google still treat onclick location as a link? Or do they ignore it?

rel="nofollow" will do it. Google treats that right and won´t follow the link. But noticing isn´t suppressed with that solution. Perhaps don´t post it as a link... even JS will do a good job I think.

rel="nofollow" will prevent google from using it in their pagerank algorithm, but won't prevent them from following the link. To prevent them from accessing content on your site you should use robots.txt.
