Blackholing as SEO?
Posted by multippt
Of course, Google have explicitly mentioned that backlinks will add to a site’s PageRank. However, through experience it is found that outbound links have an opposite effect to backlinks. So, before you add that link to your site, think again. Similarly, internal pages act as outbound links, except that you have more control over them. This is based on the assumption that links act as the path where the highly fluid link juice can flow. Thus, the theory might be useful in search engine optimisation (SEO).
Blackholing?
The idea of a blackhole is that it traps everything inside, letting little stuff come out. Link blackholing employs the same idea. Some backlinks, few outbound links. Of course, don’t forget internal pages - these links pass PageRank too. So, for ideal blackholing, you should have some backlinks, few internal links, few outbound links. Thus, it traps some link juice in your site.
Of course, Google is doing something
Google penalizes sites for attempting to over-black-hole. So, do share the juice by having outbound links. Each site does have a certain level of black-holing - remember, all objects have gravity, so each site probably still gets to keep some juice. So, guess who are the larger link black-holes? They are none other than the higher PageRank sites! Employ a certain level of black-holing (i.e. getting backlinks to compensate for outbound links), but not too much otherwise people will not want to link to you.
Reciprocal linking?
If reciprocal links do add to PageRank, it implies that backlinks add more to PageRank than outbound links. So, feel free to exchange links. Though, reciprocal links definately add much lesser link juice compared to a one way link. This is because reciprocal links employ backlinks and outbound links, thus the weight of reciprocal linking has decreased.

The theory of backlinks and outbound links make it sound like you need to hurt someone in order to gain,since to have a backlink, you need to have an outbound link from a site which may decrease link juice on the page. Nonetheless, feel free to do outbound linking even if it means a loss in link juice, because there would be someone out there would be thankful to you.
