I think they may also be looking at traffic levels, I got rejected on a new site based on page type of either personal or search engine results.
Since, I don't have a search engine running on that site (but do on another) and have no personal information on the site of any kind. The site and my application have me DBA as myself, that is for tax reasons, the IRS allows that and it allows me to look into new income opportunities without the cost of setting up companies untill that option becomes cheaper.
I was hoping to use adsence on the new content so i would not have to hunt down sources for income. However, i found a site that has affiliate links which are great for a large percent of my new content (and that other site appears to be doing well). I am now affiliated with that program.
They clearly did not look at the interlinking of the site or they would of seen the site I am moving to the new one, which has alot of traffic and is 100% business related.
Anyways, I've got an email address that i can reply to (same one as everybody else has), and address my site with them in the future. The new pages with little traffic only need to make money if they burn bandwidth, I've got another site lined up for 75% of where I expect growth. Because i am moving another site I already know my bandwidth will be growing ... but i have reduced the cost of my bandwidth and am adding alot of new content, I've been working ... later i will contact adsense again.
