I have a blog that is about 5 years old it has a PR of 0. The domain name is random and none specific. Now whenever I want something promoted, I do a little keyword research and write an article and post it on my blog. Google indexes it and within a matter of days it will be on page one or page two of the search results for my chosen keyword. Sometimes it sticks - sometimes it doesn't. This seems to depend on the amount of backlinking and bookmarking I do for the said article. Now - I have also built a few linkwheels. Sometimes using original quality content and sometimes using highly spun 40% to 60% unique content. Now sometimes these get indexed and sometimes they don't. Sometimes they end up in the on page one of the search results and sometimes they don't. It all seems pretty arbitrary. So this leaves me with a few considerations: Aged Blogs Having the keyword in your URL is important. But they keyword doesn't have to be in the domain name or even the sub-domain. It can be http://www.yourdomain.com/keyword. This seems to work very very well on aged blogs at least. With an aged blog the content doesn't need to be related to the 'context' of the blog. You can pretty much rank for anything so long as it isn't too highly competitive and so long as you have done good keyword research and written a quality article. It will rank regardless of related content. Linkwheels The quality of content seems to be largely irrelevant. You can rank with keyword rich heavily spun content. I have multiple articles on the first page of Google for a specific keyword which are in essence the same article. Whether or not you rank for a linkwheel article seems to be pretty random and influenced by a lot of factors that are outside of our control - or at least factors we cannot see. Quite often linkwheel spokes won't even get indexed, regardless of the quality of the content. In short this leads me to believe that building a number of quality aged blogs is a much better idea for long term results. Long term is import as I am selling my own products and not involved with CPA or affiliates. The fact that context appears to be irrelevant for aged blogs is a massive bonus. Now here's the interesting part. Building linkwheels from articles on aged blogs. Then building traditional linkwheels around these aged blogs. This is something I have yet to try, but I am interested in what people think. Also there are a few other factors that bear consideration: My aged blogs are on privately owned domains. How much does this contribute to a blogs ranking power? How powerful can aged Web 2.0 blogs be? Are they potentially just as powerful as privately own blogs? All this can do with some testing. I have an unused domain that is about 3 years old now - I am going to try some testing with this and see what happen. I also have a few aged Web 2.0 properties that I will work with and see what happens. Finally - with all the blog building tools out there - such as LFE - it would be very easy to build an entire network of blogs and just keep re-using them for each project as opposed to building an entire new linkwheel network for each project.
