So if i register mycar.com and mycar.net. I create unique articles for both but with same keyword 'my car'. Is it possible to rank both sites or will Google penalise this....assuming both hosted on same host account? Just wondering as i have two domains as above and for some reason only one of them ranks top ten for my keyword while the other is on page 9! Even more weird is that every now and again they swap places! So the page 9 site goes into top ten and the other site dsappears for a while. Almost as if i can't have two sites ranking at thesame time?
