If you are looking for information on particular subjects then you can never go wrong with over 800 million pages in the World Wide Web but according to a new study by a team of computer scientists Internet search engines are only able to help people reach half of these. With regard to indexing the Web, search engines are making less of an effort to do so. What a firm for computer and communications owns is an institute.

The top six search engines are able to cover 60 percent of the Web and this was found out after researchers conducted a similar study at the end of 1997 and here the best search engine was able to hit a third of all sites. It was from a report last February by a renowned journal where there were information about how only 42 percent of all sites was found in a test of 11 top search engines and no single program that existed could cover more than about 16 percent of the Web.

Promised by the Web was an effort to equalize access to information but because search engines often tend to index the sites that have more links to them people are able to view these popular sites and not those which may carry loads of relevant data.

Just 14 months after they came out with their first estimate of having 320 million pages of Internet information and content that they found the number of pages to be twice this initial estimate and so there is definitely more ground that needs patrolling. In terms of the Web, it has 6 trillion bytes of information but 20 trillion bytes comes from the library of congress. When it comes to publicly available servers, there were 3 million with about 289 pages per server and this resulted from the random surfing exercise of 2,500 Web sites done by researchers.

But they caution that just a few sites may have millions of pages, which could make the true amount of information on the Net even larger. What they did was run a test on the servers and the results came back with data showing how 83 percent of them contained commercial content company Web pages and catalogues, 2 percent had pornographic content, 2 percent were personal Web pages, just about 3 percent had information on health, and about 6 percent had information on science and education. Responsible for making so much of the Web hard to find are the techniques search engines use and not so much the volume.

User registration as well as following links to find new pages are the two main methods utilized by search providers in finding pages. A biased sample of the Web is what search engines make according to researchers for they use links to find new pages in turn leading them to find and index pages that have more links to them. In this situation, there is no inability when it comes to doing the indexing, the problem here is that resources are being devoted to be beneficial to users in a different way like how free email services are today.

Fairly simple are what most of the information requests are and because of this a search engine expert says that a lot of people fail to notice what they are not seeing. This imbalance in cataloguing may continue for a few more years, but ultimately I think it’s going to reverse because the rate of increase in computer resources is going to be faster than the production of information content by humans to be posted on new sites.
