Interesting method and you made some great points, but is a bit expensive. 30 articles for each site would cost at least $150 dollars each. There's a way to do this without using so many articles.
Also have you noticed less traffic from the search engines because of using subdomains instead of seperate domain names?
Is it important that the domains are just like that? or is it just as good if it says like "www.onfinance.com.au/boats" instead of "www.boats.onfinance.com.au" ? thanks for the great tips
how much to original articles go for anyways? if you've already got a base of operation in adsense, $150 for 30 articles doesn't sound bad at all... it's just slowly adding new content over time to build up your site.
What I'm afraid is when buying articles from someone who write them on command, that he will sell them again as a package or use them later in article directories for adsense money. How can you be sure to get original articles at $5 a piece? I know in some countries they have a low cost of living, but still...
I agree.. maybe signing over a NDA or something to the effect of a contract as the owner of the articles once it's delivered?
