While books on marketing and advertising on the Internet abound, practical technical guidance is scarce. This is the first book to provide businesses and entrepreneurs with hands-on, technical advice on building a successful Internet commerce center. Covering all of the vital enabling technology in depth, Internet Commerce explores the four revenue models currently in use: Direct sales and marketing of goods and services; sales of advertising space; charging fees for the content accessible through Web sites; and charging fees for online transactions, searches, or links. The book also discusses technical limitations of electronic commerce over today's Internet, and describes successful applications.
