Advertising over the Internet and the World Wide Web is a big business. Few years back this was an industry fighting for its existence, but not anymore. The monetization of Web site traffic is a known path.

Advertising on the Internet is constantly changing. Many sophisticated tools are available to measure traffic and visitors behavior. A wealth of information and statistics is available for advertisers to make the best advertising decisions.
