Finding Pages With Two Main Methods
Information on different topics is available from the World Wide Web with more than 800 million pages of relevant content but based on a new study by a team of computer scientists people are only guided to half of these pages by Internet search engines. In terms of indexing the Web, search engines are failing to exert much effort. The institute is owned by a computer and communications firm. You will find that further information on search engine optimisation is on that site.
Conducted was a similar study at the end of 1997 and researchers were able to determine that collectively the top six search engines were able to cover 60 percent of the Web and the top search engine was able to hit one third of all pages. Coming from a renowned journal last February was a report stating that what was found only comprised 42 percent of all sites in a test of 11 top search engines not to mention there was not a single program that was able to cover more than about 16 percent of the Web.
Considering the big promise from the Web, it involved equalizing access to information but nowadays search engines are more likely to index the sites that have more links to them and these popular sites gain much visibility and those which may carry new and quality information are frequently neglected.
The first estimate was placed at an estimate of 320 million pages but there is more Internet information and content that needs patrolling after the new estimate 14 months later finding out that there were twice as many pages. In terms of the Web, it has 6 trillion bytes of information but 20 trillion bytes comes from the library of congress. After their random surfing exercise of 2,500 Web sites the researchers found out that there were about 3 million publicly available servers having 289 pages per server on the average.

The amount of information on the Net could be larger and this is what they mentioned considering the fact 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. The volume is not the reason why so much of the Web is hard to find as this is due to the techniques used by search engines.
Search providers typically have two main methods for locating pages, following links to find new pages and user registration. 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. Actually, this is not because they do not have the ability to do the indexing, this is because resources have been devoted to other uses that users may find beneficial like free email services and the like.
From a search engine expert came about the information that people do not easily notice what they are missing for they often resort to making simple information requests. For a few more years is how long this imbalance in cataloguing is expected to continue and this is because the rate of increase in computer resources will be faster than the production of information content by humans to be posted on new sites.
