Amazon has entered the search engine wars with its own entry called A9. A9 uses tabs and columns to allow people to search for websites, images and books. A9 users can also create bookmarks and diary entries. The A9 search engine also includes website information like traffic and contact information that it pulls in from Amazon.com's Alexa service. Amazon.com has a big hurdle to climb to compete with Google, Microsoft and Yahoo. However, Amazon.com might be able to get more search traffic by finding away to hook A9 into its affiliate program -- which has hundreds of thousands of members.
