I was asked to start this thread because many people don't know the benefits of ABC linking.....some don't know what ABC linking is for that matter
so, lets gets started...
In my opinion, ABC linking is the possibly best form of linking (link trading) you can do for a blog. It is the process of taking 2 of your sites and 1 of someone elses and linking them all in a row
so, if you have SITEA.com and SITEB.com and someone else has WEBSITE.com, you would link to WEBSITE.com from SITEA.com and WEBSITE.com would link to SITEB.com
so, it goes SITEA.com > WEBSITE.com > SITEB.com
the benefit of this is that if you do this enough and this is all you do, you will end up with tons of inbound links to your site, and the outbound links that you do end up with will be classified as "relevant" in the SE eyes.
When googlebot comes to your site and see that you don't have any reciprocal linking going on, it LOVES that.....the more incoming links (without reciprocated links) you have coming to your site, the better.
The only downside to this is that it requires precise organization...I actually have a white board in my office with all my sites listed on it and lines drawn between each one so I can keep track....and trust me, even with that it gets crazy confusing.
I have one blog that I have been working on right now,
www.alexislyn.com
I am working on making this 100% inbound links...so, when I go to do link trading, I tell people to link to that, and I will link to them from one of my other blogs with higer pr....I expect to go from pr0 to pr3 in the next update just because I am being so careful about only getting links in to that site.
I don't know if I covered everything, so I am here for questions, but remember, just like you, I am always learning also, so if I don't know something I can find out real quick from some of my se pro friends, but it might take me a few
