I recently signed up for Chitika which is a good alternative for adsense. The ads appear similar to adsense ads. Chitika has certain features which are very unique. The ads appear on your blog only for those visitors who reach your blog via a search engine. For example when someone does a google search for the phrase “Bidvertiser Tricks” and if your site comes up on the SERP page and if the visitor clicks on it and reaches your blog then he will see the ads but not if he reaches your blog directly. This kind of features eliminates accidental self clicking of ads as they don’t even appear when you are modifying your blog. But your earning entirely depends on how good your blog is far far search engines are concerned. Chitika pays through cheque (minimum balance $100) and Paypal with a minimim balance of $10 for withdrawal. For more information click here.
