What is the Deep Web?

ADS BY GOOGLE

The term translates as "Deep Intertet" or "Dark Internet", I think that the term comes from a comparison between this "dark Internet" with "deep" waters of the seas. The fact is that the ninety-five percent of the "deep" waters of the seas of the world are still unexplored, as well, ninety-five percent of the Web pages do not have able to index or index.

Take your break, of truth: "San Google" do not knows everything, if you will allow me the joke. I wondered when the very natural: why? The simplest answer, and it is that I prefer, is that people want privacy. There is an infinity of "private pages" that expressly requested not be indexed in different programs or Internet such as Google, Yahoo, Bing, Duck Duck Go search engines and other similar. Sometimes search engines can not index pages as they are protected by passwords or are in a format that can recognize. At other times it is because the pages are part of a database such as magazines, newspapers, encyclopedias, dictionaries and many others as used to manage the contents of libraries, although most public pages is necessary to query the database to access the same.

Of course, that being impossible to index as many pages we have are very speculative data on the size and the why. For example many of the private pages are dedicated to bring together people who want privacy, for example the "Strip" and the communities that have affinity for that culture. Also in this category would fit pages with themes that actually does not contribute to the global community, such as those that promote illegal activities or make contact between people with these interests. Of course, there are also sites that serve niche or small communities that contribute significantly to these, but in very specific issues that are only of interest or knowledge of these small groups of people.

Finally, we must also consider the technical limits of the search engines: the process of searching for new pages in the Internet requires resources, both energy and computer, all limited. Thus it is that the people who design the indexing methods seek to streamline the process by giving priority to "places" on the web where there are more likely to find the content useful to users.

But avoid index pages may end up depriving the user end, namely that searching on the Internet for relevant information that could provide answers to their questions, and therefore is the most important search engines to make constant efforts to improve and expand its infrastructure to at least overcome the technical limitations regarding the amount of pages that can be indexed in their databases. Also call for cooperation by the site owners to avoid duplicate pages and other problems that end up wasting resources.

It can be said that today a large part of this "Deep Web" or "Internet deep" already part of indices of pages in major search engines, and while this unexplored part of the Internet never know at all, mainly for reasons of privacy of those who create protected content, the information that we find on the web is extremely wide, to the point where we can hardly "Digest" this immensity. And it is worth mentioning that any human tool dark or deep Web can have good or bad uses (as in the case of illegality).
