I have a small travel site advertising one accommodation. Around 40 Pages total including the usual fluff pages. A year ago during an update relegation I made another site and instead of optimising it I tried to do exactly the opposite of everything I did with the previous site. Now both sites are ranking first page for many keywords. Used to get about 150 visitors a day to one site. Now get about 350 total to the 2 sites. My hope was never to have both sites ranking. Was just hoping to cover my bases. Both sites are equally useful. Interesting to note the unoptimised site converts much better.
