Promote Survey offers on websites

How should you promote them on your own websites, with image links in the sidebar, or with article/reviews of the survey, with a link to the survey at the bottom? I have a make money website and i can use offers which link to surveys allowing people to earn cash, so its an ideal niche, how should i promote it on my site? Would i need an article on each survey offer, or would ads in the sidebar be okay, i already have 3 adsense ads though so there may be too many ads by then

I have seen most sites promoting surveys by offering fake download links for softwares, music or movies and asking users to complete the survey to unlock the download link. It is a pretty good strategy and works very well on novice internet users.
