Microsoft adcenter is a great way to get your feet wet with Pay Per Click (PPC) marketing. Microsoft’s search engine holds the 3rd largest market share in the world behind Google and Yahoo. This makes it perfect for beginners to PPC marketing because you generally have to pay much less per-click for your traffic.

After signing up for Adcenter, there is an online tutorial that will guide you through setting up your first advertising campaign. Microsoft will also snail-mail you a sizeable getting started
packet with tips on promoting your site with their system. The information in that packet is solid, and will give you a good foundation for any future PPC marketing you plan on doing.
