I use Adwords to promote my product/service. I am thinking about starting a new site with different format/wording/structure/focus that would promote the same product/service. Would Adwords have a problem with me running Adwords for two different sites & two different ads on the same Keywords on the same SERP page? My motivation is that the existing site does OK in the SERPs (lower page 1 & top of page 2) and I can't move it up. I want to create a new site with different SEO/format/wording & importantly a more relevant domain name, that may do better & get more buzz... & also keep the old one.
