There have been many intensive discussions here at WPW about many link schemes, where the last is this now 13 pages long thread about inbound links. As explained in my post #639
link selling and buying have been also been relatively extensively discussed.
2. Backlinks to avoid.
This backlinks to avoid article is a classic article about link schemes that you shall avoid. I think it is not fully up to date, e.g. on links and frames. It is fairly long time since I have accepted any link exchange after Google started penalizing sites that participated in link selling / buying and triangular link schemes. Triangular link schemes. There are thousands of them, many good portals have participated and participate in triangular linking. I doubt many of them even know about the rel="nofollow" attribute. Now, if I accept a link exchange, I rel="nofollow" the link and require that the link partner do the same. So what have happened to these portals that are based on triangular linking?
3. You are who you link to.
My own view on IBL's is that IBL's can not hurt you. You can only get what you deserve if you buy inbound links, that is what I personally have called zeroed out. We also know that Google operate with various penalties.
The worst. I personally have experienced, is a link that later redirected to a porn site (normal porn links are legal) but personally I can not think of anything worse for that site. The blame is of course on myself, since I did not do a good enough due diligence before linking out. That experience have made me very skeptical to new links, especially those that I find on forums and social network sites. In stead I try to make my old link collection that I started collected in 1995 more focused. The aim is not to get a biggest possible link collection. But outbound links can hurt you. So outbound linking is also a risky business, even if it is a free organic link.
4. A static banner link model.
Some weeks ago, I wrote this article, "pay per static brand link a better solution for professional publishers." The more I think of it, the more I reckognize that that is the best link model for the professional publisher.
5. Have Google achieved what they aimed at?
By rel="nofollowing", theoretically a large part of the web can be invisible to GoogleBOT or am I wrong? At last it has given me a lot of headache. Hopefully it has made the web more semantic.
6. Meaningful comments and remarks are welcome.
As a minimum, before you comment in this thread, I would appreciate that you read the article:
Backlinks to avoid. If you give a meaningless comment, it may be rewarded with a red rep point, so think before you post, since I don't want a new marathon thread unless it is natural. Good comments may get a green rep point.
