Website owners have been making money with Adsense pay-per-click ads for years. For Google, growing its AdSense user base will help it maintain an edge against rival advertising networks. To do so, Google wants to make it as easy as possible for people to sign up for an account and begin generating revenue.

Even though Google gives a large percentage of revenues to companies in the AdSense partner network of participating sites, they still make a lot of money. AdSense partner network revenue hit $1.45 billion, a third of total annual revenue, in the third quarter of 2007.

Recently, the Adsense blog announced Google's latest approach to growing the lucrative business segment. Called "Newbie Central," the assorted step by step documents focus on the features, policies, and tools available to new webmasters joining the Adsense program.

The money people can make through AdSense figures prominently in the minds of webmasters. Newbie Central dedicates some attention to the topic in its Earnings and Expectations section.

Newbie Central also provides suggestions on ad placement and optimization, and the ability to use other potential revenue generators like AdSense for Search, and Referrals, on a site. It's good for webmasters, and if it helps with more adoption of AdSense, it's even better for Google.
