Alexa Web Information Service Launches on Amazon Web Services Web Site

Web Service Available on Amazon Web Services Web Site Lets Developers Build Innovative Applications Using Data from Alexa`s 4.5 Billion Web Page, 16 Million Web Site Crawl

SAN FRANCISCO--Oct. 11, 2005--Alexa Internet, a subsidiary of Amazon.com, Inc. (NASDAQ: AMZN), today launched the Alexa Web Information Service (AWIS) on the Amazon Web Services Web site. AWIS offers software and Web developers access to more than 100 terabytes of Web site information and popularity data collected by Alexa`s Web Crawl of more than 4.5 billion Web pages on 16 million sites. Developers can sign up and get started using AWIS at the Amazon Web Services Web site aws.amazon.com/awis.

"We`ve only scratched the surface of the possible applications of the data captured by the enormous Alexa Crawl. There are many more types of businesses and people that we believe would benefit from customized applications of Alexa data," said Alexa Product Manager Geoffrey Mack. "Rather than build all these applications ourselves, we are opening up and giving developers the opportunity to build them and create their own innovative businesses using our data."

Developers can use AWIS to answer difficult and interesting questions about the Web, and programmatically incorporate these answers directly into their applications. The following are types of Web site information and popularity data that are accessible to developers through AWIS:

-- URL Information - useful data about millions of Web sites, including traffic rank, load speed, related links, site owner contact information, and adult content identification.

-- Browse Category - everything that is needed to build a site browse tree, including lists of sub-categories for a top-level category, most popular sites in a category, and all sites within the category.

-- Web Search - Web search based on Alexa`s crawl, providing robust support for advanced queries allowing developers to construct difficult queries and incorporate the answers into their applications.

-- Crawl Meta Data - meta-data for specific pages found in the Alexa Crawl, including size, checksum, frames, images, and links.

-- Web Map - topographic representation of Alexa`s Web crawl displaying all links in and links out of specific pages on the Web.

Getting started using AWIS is easy and risk-free. There is no charge for the first 10,000 AWIS requests made by a developer each month and each additional request costs only $0.00015. For example, if a developer makes 12,000 AWIS requests in a month, the cost would be just $.30. All of the documentation, code samples, and sample applications developers need to begin innovating and building businesses today using AWIS is available on the Amazon Web Services Web site aws.amazon.com/awis.

"We are excited to work with Alexa to offer AWIS through the Amazon Web Services Web site," said Amazon Web Services Vice President of Product Development and Developer Relations Adam Selipsky. "With the powerful data that is being exposed and the low cost to access this data, we look forward to seeing the innovative businesses developers create using AWIS."

Early AWIS Successes

AWIS was first released in beta in October 2004. AdBrite participated in the beta and used AWIS to enhance the services they offer customers. AdBrite is a marketplace for buying and selling advertising space on thousands of Web sites. The company uses AWIS to provide prospective advertisement buyers with important information and statistics about the Web sites selling site space through the AdBrite marketplace.

"AWIS is vital to our rapidly-growing business," said AdBrite Chief Executive Officer and Founder Philip Kaplan. "The fact that AWIS is a Web service means that we dedicate minimal software development resources while offering a service to our customers that is invaluable in their decision-making process."
