Even if you can get traffic to the site, the banner farm technique doesn't work in converting traffic. However, with multiple banners listings, almost all web viewers will immediately click the back button, and even if they decide to have a look, multiple banners are confusing. As an alternative, be selective in the affiliates you join. Choose programs that work and stick to them, never confront the viewer with more than a couple advertisements on any one page, and if you do vary the advertisement, make them seem like content. Don't only use banners.
Statistics show that banner ads are ineffective.
Additionally, they have lull too many affiliates into a false sense of what it takes to succeed. Banners can build brand. Banners can achieve sales, but for those of us who only get paid when people click or when people buy, banners are not that effective. If you put up a banner on the top of a page that gets a thousand views per day, you are going to be fortunate if you get five people to clickthrough. If the desired action requires paying something, it could take you days to get one sale.
