Hi,
My main site
www.discountdomainsuk.com has an article bank of approx 900 articles, Iwanted to try and monetise this by adding Google Adsense, unfortunately Google has a policy of not allowing adsense to run on Domain Registration sites.
I have complained to big G because a number of competitors run the program on similar sites, but to no avail etc
So really the article site started out to help cover the costs of my main business.
As time has gone by, I have also come to realise that the article bank is a good resource to help my customer who are typically net newbies. Instead of expanding my domain site, I decided to go down the dedicated article site route.
Hope this explains things
Clare
