Bidvertiser in my opinon, is another good ppc advertiser. I have used them personally with great success. I have used them on both sides of the ppc "game". I have been a publisher for them (serve ads) and an advertiser wth them (received clicks to my site from their ads) also. Their ads truly were very targeted and I received many quality visitors with them. If you have never used any ppc company before, I would definately reccomend them. For more information, visit
