Accessibility and Distribution of Information on the Web
This page summarizes our study in the journal Nature:
"Accessibility of information on the web", Nature, Vol. 400, pp. 107-109, 1999.
Frequently Asked Questions There are two categories of web analytics; off-site and on-site web analytics. Off-site web analytics refers to web measurement and analysis regardless of whether you own or maintain a website. It includes the measurement of a website's potential audience (opportunity), share of voice (visibility), and buzz (comments) that is happening on the Internet as a whole.
Search engine coverage has decreased |
Search engine coverage relative to the estimated size of the publicly indexable web has decreased substantially since December 97, with no engine indexing more than about 16% of the estimated size of the publicly indexable web. (Note that many queries can be satisfied with a relatively small database). |
Unequal access |
Search engines are typically more likely to index sites that have more links to them (more 'popular' sites). They are also typically more likely to index US sites than non-US sites (AltaVista is an exception), and more likely to index commercial sites than educational sites. |
Out of date |
Indexing of new or modified pages by just one of the major search engines can take months. |
Information distribution |
83% of sites contain commercial content and 6% contain scientific or educational content. Only 1.5% of sites contain pornographic content. |
800 million pages |
The publicly indexable web contains an estimated 800 million pages as of February 1999, encompassing about 15 terabytes of information or about 6 terabytes of text after removing HTML tags, comments, and extra whitespace. |
Low metadata use |
The simple HTML "keywords" and "description" metatags are only used on the homepages of 34% of sites. Only 0.3% of sites use the Dublin Core metadata standard. |
The web is transforming society, and the search
engines are an important part of the process. The web and search
engines represent a significant improvement for communication,
providing efficient access to an increasing amount of
information. However there are limitations to the current search
engines, improvements to which may help to maximize the benefits of
the web.
85% of users use search engines to find information
(GVU survey). Consumers use search engines to locate and buy goods or
to research many decisions (such as choosing a vacation destination,
medical treatment or election vote). However, the search engines are
currently lacking in comprehensive and timeliness, and do not index
sites equally. The current state of search engines can be compared to
a phone book which is updated irregularly, is biased toward listing
more popular information, and has most of the pages ripped out.
