The similarity metric measures the degree of similarity between two or more web pages in the context of clustering schemes; that is, the organization of information according to its most important attributes. There are three types of similarity metrics: content, links and usage.
- Content-based similarity. This is measured by comparing the text of two web sites.
- Link-based similarity. Compares the structure of the links on different web sites to find other similar sites.
- Usage-based similarity. Evaluates patterns of access to documents on a site.
Juan Palacio in Navegapolis writes that when Telefonica, the telecommunications giant of Spain, appears in blogs, it is normally the butt of criticism.

There are some 680 pages of data on such topics as the number of people regularly using the Internet, types of usage, use of e-commerce, use by organizations of public administration, telecommunications, e-learning etc.
