However do avoid any third tier PPC services who may promise cheap traffic but may end up sending only bots and charge for it!
The other PPC programs have differences in the structure of the interface, how they approach keyword approvals and some of the terminology they use, which may be similar to adwords with some, so called innovations, built in.
