If u wanna get really high numbers either u need to have a site which is indexed in google,yahoo etc.. or be a respected member (guy with good reputation) on a site like w-bb with a mega thread with working links. It takes time and ppl who earn a lot has a lot of hard work put into those earnings (re up dead links, making custom screen shots...etc) and remeber ppl will never give their secret away coz they have learned it the hard way and this advise is as good as its going to get. U'll learn through experience.
