I have been running two or three portals running with reasonably good number of traffic. Presently I am running Google AdSense to gain little revenue. Few of my popular sites are Ecommerce Auctions, B2B Treadleads, Daily news, Community network, blogs etc.. Can anybody suggest me how can not get commercial Advertisement to my website. How can I reach to the company who is searching good site to post their add. Regards Nazrul
