What is PPC?
PPC stands for pay per click.
It means user will get paid for every clicks.But the difference between PTC and PPC is that
in PTC you will have visit every link given to you in order to get paid.But PPC is an
advertising system for publishers and advertisers.And publisher means website owner and blog owners.They will have to place ads on their sites and whenever a user clicks the advertisement he will get paid.This is the main differences between PTC and PPC.
