http://www.whatisonion.com/ :- What site you have created..Just to get the Ad sense approval you have written one article and on the rest of the pages..... work on the content..lots of efforts is required for the on page optimization....
niice clean site - one ;ages of content is not enough for even a microsite. You need a privacy policy and a disclaimer and a contact page. Search your plugins fro these.
Might become a useful site. The micro niche idea is good, you just have to do a little more work on content, everybody knows what the onion is and how it smells. Go deeper, don't afraid to provide more specific, even scientific information.
Yeah, you right. I think same for that. Btw, your site looks good and I think to much ads, you must reduce one.
The site is kind of nonsense and it would be surprising if you make the big bucks out of it. But... who knows, sometimes the simplest ideas are successful. Good luck.
