About a month ago, we decided to begin advertising Pay Per Click Universe on PPC search engines. Since our website is informational, most of our revenue comes from our sponsors and commissions that we receive from some PPC search engines and tools when we refer new clients to them.
As far as most advertisers are concerned, there are really only two pay per click search engines that deserve their attention - Google's AdWords and Overture (owned by Yahoo!). After all, these are the most popular search engines that dominate the industry in terms of traffic, technology, and popularity.
Recently, an article appeared on CNET stating that Google has filed a lawsuit against a Texas-based company alleging they fraudulently abused the Google PPC system to profit from the advertisers' ad spending.
