Though i am using google adsense form a long time, i do not know weather there is problem in using adsense and adbriter at the same web site. I have used the code in the same site. But i have seen that the google adsense code is there but the advertisement is not loaded properly. Wait for your suggestion brother.
Should be no problem, only just two different company's ads . however Put too many ads, the page will be appeared messy, and sometimes there are some problems to load, such as google ads do not display properly.
