Now you can sit back and see what results you get. Let the ad go for a month and see how many clicks it takes before anyone buys from you. If it's not bringing back enough money,you should try to figure out what's wrong.Is it the ad or is it your web page? Anyway, try to fix it and let the ad go for another month. When you have a reasonable return of investment(ROI). It's just to let the ad go without any more work on your part. It's going on auto pilot. Just remember to check it once a month to see if the ROI are dropping. If it's not bringing in enough money,you can find another product,and do the same thing all over again.
