Chances are you wont make any money with a site using adsense for revenue... especially with cooking keywords. You are better off making a really good site, then getting REAL sponsors who want to advertise on your site. On a site note, I've used Adsense on my siteS for 3 years now, and have made a total of $290. I recently start using Adsense for domains, and in just under 3 weeks I made $800
