Link black-holes you should watch out for
Posted by multippt
If you studied quantum physics, you probably know about black holes. Even if you didn’t, you probably heard of it right? A link blackhole is like a blackhole - it eats links, but gives back few links that are taken into account by search engines in ranking. Generally, if they get popular enough, they would become a authority site - if many link to it. However, it may not generously give back the favors (but if you do manage to get a link from one of those link black-holes, they are considered incredibly high quality).
