Hello All An interesting topic I see many people asking on the internet. I see allot of people No Following there outbound links on there website to reduce the loss of link Juice. Now we all know that no follow allows you to control what Google Relates to your website, but when do you really use it? When does it pay to follow a site? Does following twitter and facebook Pay in terms of SEO to follow? or does this dilute link juice and should we all no follow the links? If we no follow the social media how does google know we have social media on our site?
It depends. IMHO, providing a dofollow to a quality site should do no harm and might in the long run actually improve your "trust" with the search engines because they realize that you link to quality sites. On the other hand, if you try to keep all the link juice within your site, then the search engines with also notice than and it might hurt your rankings. Of course, use "nofollow" for everything you do not trust. On the other hand, my blog (SEO translator) has the comments with DO-follow, so as to entice people to comment (but I moderate the comments and delete ruthlessly anything not providing of value to the discussion - no free ride here). In this case, unless it is really a bad neighborhood, I don't object to linking.
This. Use nofollow only for non trustable links like comments. If you are referring to some website yourself then leave it natural.
Well, all my comments are moderated, so if there's something I don't like then that site will quickly go out. The fact is, that if I provide dofollow links, people will be tempted to provide useful comments (because I weed out all others).
