If you are hosting a website or a blog, there is a good chance that you have also integrated ads into your content. There is nothing wrong with making a bit of money when you work hard. Everybody knows about Google Adsense but there is a lot of alternatives available. I've started building a website (http://ads.crombz.com) which is displaying the final result of those ads once integrated into a website. More services will be added in the next few weeks but you can already see Qadabra, SpeedyAds and more. I will eventually report about performances compared to Google Adsense. Which service are you using on your website/blog?
