BuySellAds is a direct banner advertising company where you can submit your blog for approval and once its approved you can add their empty banners to your blog/website. So, the advertisers will buy those empty spaces on your website and put their ads for 30 days for which you will get paid. But getting successfully approved from BSA is not a game of kids, their rules and regulations are very much strict even stricter than Google Adsense....
