Not being a jerk, just i see post everyday asking about what is the best ppc network out there,
When push comes to shove and i want to inquire about something i will go to google.com and search, and about at LEAST 90% of people who are interested in something will use google or bing
So with that said the Best PPC network out there is Google adwords hand down then i personally think Bing comes second
Lets be real other networks offer cheaper clicks, and therefore a lot of affiliates consider this to be great, I am old fashion you get what you pay for and yes Adwords may cost more per click but you are defiantly getting more targeted traffic with them then anything else, and in the end if the advertiser is not happy you will either be pulled from a offer or worse yet not paid. So my theory is to pay a little more to send targeted traffic and make the advertiser happy.
