How can Spurl.net cover its costs?

Spurl.net’s core business is in mining information about the World Wide Web from our databases. Note that it is information about Web pages in the database, NOT about the Spurl.net users, whose privacy we respect greatly (see our Privacy policy).

The information we mine includes web site popularity lists, relationships between pages and sites spurled by users with similar interests and how users describe and categorize these pages. This is of most importance when you consider that users communicate in different languages, have many different viewpoints, and search for information for a wide variety of reasons. Among the customers for such information are search engine companies, web page directories and other professional web sites and services that can benefit from a unique source of human information about the Web.

For this reason, we can provide you with the best online bookmark manager on the market and you only pay for it by allowing us to aggregate information on how you, and thousands of other Spurl.net users behave on the Web.
