Q: How can I get a list of all top web sites on the internet?
The list of top web sites is available through the Alexa Top Sites web service.
Any application that links to or displays information about web sites can be enhanced with data from the Alexa Web Information Service. What you can do is only limited by your imagination; some ideas include:
- Using the URL Information action to provide traffic information about web sites on your search result pages
- Using the Browse Category action to build a web directory on your web site
Any developer who can build applications or services based on XML can use the Alexa Web Information Service. The service is designed for developers who wish to display data about specific web sites, and the internet, as a whole, in their applications and web sites.
URL Information offers access to Alexa’s information about web sites, including Traffic Rank, Related Links, Contact Info, Site Stats and more. The URL Information action is fully described in the documentation.
Alexa gets its traffic data, including reach, page views and rank information, from a global panel of web users. The panel is used as a statistical sample of Internet usage to extrapolate overall traffic patterns and web usage information. Details about Alexa’s traffic data can be found on Alexa.com.
During any given three month period, Alexa can rank approximately 30 million unique sites.
Alexa Internet uses crawling, archiving, categorizing, and data mining techniques to build the Related Links lists for millions of web URLs. One technique used is to analyze links on the crawled pages to find related sites. The day-to-day use of the Alexa service also helps build and refine the data. By looking at high-level trends within the millions of URL “paths” created by Alexa users, we can deduce relationships between web sites. For example, if many users go directly from site A to site B, the two sites are likely to be related.
Please note that since the relationships between sites are based on strength, Related Links lists are not necessarily balanced. Site A may appear in the list for Site B, but Site B may not be in the list for Site A. Generally, this happens when the number of sites with strong relationships is greater than ten, or when sites do not have similar enough content.
The site owners, addresses, and phone numbers shown in the Alexa service are aggregated directly from InterNIC, Whois.net, Ripe.net, Apnic.net and other sites that are in the business of registering domain names. This domain registration information is publicly available to any web user. E-mail addresses may be gathered from the actual web site or from domain registration information. If the contact information for your URL is wrong, or you would like to have it unlisted in the Alexa service, you can change it at Alexa.com. Once there, simply enter your URL and follow the instructions. Please note that it can take up to 2 days for these changes to take effect.
Site titles and descriptions are taken directly from the Open Directory (http://www.dmoz.org). If you would like your title or description changed, you can change it at the Alexa Contact Information Editor. This will update your description on Alexa but you might also wish contact the Open Directory directly in order to update the source description.
In the URL Information action, the traffic data is updated daily. Most other information in the URL Information, are updated monthly.
Together, the Browse Category and Browse Listings actions provide a web directory service. The categories and listings are based on the Open Directory, www.dmoz.org. Alexa updates the browse category nightly to incorporate any changes made to the contents of the Open Directory, and to update the popularity information.
The Alexa directory is based on the Open Directory. Alexa edits and enhances the directory by adding traffic and reviews data. You may sort sites within a category by popularity (traffic) or reviews.
No. The Browse Category action only offers a browse feature. For any given browse node (category), the service responds with subcategories, related categories, top sites within that category, and more.
