Finding patterns in data
The Alexa services are derived from our uniquely powerful combination of Web content and usage information.
Site stats :Alexa gathers Site Stats from a variety of sources to provide key statistics about each site on the web. These include: Traffic Rank and Speed which are derived from Web usage information, and Other sites that link to this site, and Online Since, both of which come from Web content. For an example of Site Stats, see the Alexa Overview page for LOVE DROPS
Contact info: Alexa provides contact information for Web sites by mining for Web content gathered in the crawl. This information includes Site Owner, Address, Phone Number and contact e-mail address. See Contact Info for LOVE DROPS
Traffic details:Web usage information is utilized to provide information about the number of page views and number of users that Web sites receive. This data is also the basis for the Alexa traffic rank and traffic history graphs. See Traffic Details for LOVE DROPS.Our goal for these features is to help people navigate the Web more efficiently by giving them all the information they need to make informed decisions about the sites they visit.
Related Links:Whenever an Alexa Toolbar user visits a web page, the Alexa Toolbar retrieves information from the Alexa servers to suggest other pages that might be of interest to the user. To generate Related Links, we use several techniques, including:
- The usage paths of the collective Alexa community- this is the most important source of our information, since these paths show us which web sites our users believe are important and interesting.
- Clustering – the hundreds of millions of links on the Web can be used to find clusters of sites that are similar and relevant to one another. We mine this data by using custom databases to find and identify these clusters.
- Users’ suggestions – we consider our users’ suggestions to augment our Related Links recommendations.
