If something looks like it is making sense, you can start optimizing it further on site too. In general, common sense, you want to make profit. If something does not work, dont spend money, and start looking for a different way to get what you want. I am not sure how much money to invest in testing (could be 1,000, 5,000 or 10,000 visitors, lets say, this is somehow up to you too). Talk to people who sell you traffic (advertising companies), they can tell you what is what too. There are people who spend $10,000 a day on this, or more, could be $100,000 too.
