Any kind of information can be obtained through the World Wide Web for it has some 800 million pages available still people are only guided by Internet search engines to about half of these pages based on a new study by a team of computer scientists. Less effort is seen from search engines when it comes to indexing the Web. There is an institute owned by a firm for computer and communications.

In a similar study done at the end of 1997, the researchers found six top search engines collectively covered 60 percent of the Web, and the best engine hit about a third of all sites. As reported by one well known journal last February only 42 percent of all sites in a test of 11 top search engines could be found and there was not a single program that could handle covering more than about 16 percent of the Web.

With regard to the Web, what is promised to do was to equalize access to information but search engines are all inclined to index the sites that have more links to them and these popular sites are the reasons why people are prevented from being able to view quality information.

More ground should be covered when it comes to Internet information and content for the first estimate resulted to about 320 million pages but just 14 months later they found that the estimate should have been twice this initial amount of pages. Generally, there is 6 trillion bytes of information on the Web but from the library of congress comes 20 trillion bytes. Considering publicly available servers, the random surfing exercise of 2,500 Web sites done by researchers resulted in a number close to 3 million with about 289 pages per server.

When it comes to the net the amount of information could be larger because it is possible that just a few sites may have millions of pages. A series of tests were done on the servers and from these they found out that 2 percent contained pornographic material, 2 percent were personal Web pages, about 83 percent of them contained commercial content company Web pages and catalogues, 6 percent had information about science and education, and 3 percent contained health information. To blame for making so much of the Web difficult to reach are the techniques used by search engines and not the volume per se.

There are two main methods when it comes to locating pages and search providers can either follow links or make use of user registration. As written by researchers, search engines are responsible for making a biased sample of the Web as they find and index pages that have more links to them by following links to new pages. Taking this into consideration, it is not a matter of being unable to do the indexing, this is a matter of making resources be beneficial to users in another way like offering valuable free email for some.

There are a lot of people who do not notice what they are seeing and this is because a number of them only make simple information requests according to a search engine expert. Expected to go on for the years to come is this imbalance in cataloguing and this is due to the fact that the rate of increase in computer resources will be faster than the production of information content by humans to be posted on new sites.
