AdSense monetized so unfortunately Google do know they're both mine. My old site got hit by Penguin 3.0 and slightly recovered on its own, many keywords are ranking again. But before it magically recovered I created a new, improved site with a clean link profile targeted at the same terms. I've got onto page 2 but haven't cracked page 1 yet. Is it possible to have 2 different properties I own on page 1 for the same keywords? My new site is much better than the first but the old one is giving me a cool $400 to $500 AdSense payout each month so I don't want to take it down really!
