Which PPC platform is best for Network Marketing?

For network marketers using pay-per-click (PPC) as a marketing tool to get prospects for their businesses, one should consider the benefits that each platform has to offer as opposed to the cost of each. As of this writing, the three biggest PPC platforms available for use are MSN adCenter, Yahoo! Search Marketing, Google Adwords. Please note that not all of these platforms are built alike.

Of the three platforms, Microsoft’s adCenter is the newest of the three. The one thing they offer to appeal to network marketers is a keyword research and optimization tool which is based on Excel, which is a program that enables you to manage keyword lists and maintain precise metrics.
