I'm behind the site. Would you rather I replaced adsense with a paid advertising banner? What would you like to know in an 'about us' section? I'm open to suggestions. Remember though that there is no cost to use the site.
Just with Adsense, it's something I see a lot of affiliates using and few merchants. Usually when an affiliate sees a merchant using it, the thinking is the main business must not be doing so well for them to put that up. I use Adsense on pages if the affiliate links aren't converting well. Your core business should be bringing in the main money, Adsense is more nickel and dime type stuff.
About Us page, even something simple like what Bido has -
http://www.bido.com/Info/About+Us and some of the links below on that page. For me personally and I think a lot of people, they want to know who's behind the sites they're putting their domains on. Even other sites I've asked about like cax.com. If you get to that site from let's say a search engine, it's a horrible setup. There's no about us, no privacy policy, no terms of service, no info on how to submit etc. I think you get more of that info if you get there thru domaining.com. But go to that site straight, type in, search engine, link from another site. There's just nothing there explaining anything.
