We are launching a new website soon but we want to test it first to see if if converts as well as the current site. We were thinking about doing an adwords experiemnt on one of our camapigns and direct 50% to the old site and 50% to the new site so we could compare. We would no index the new site while we are testing this. Do you think this is a good way to test it?

The new site would have a slightly different URL for the test.
