In today’s competitive market, Internet Research has become main tool of investment. Indeed it has proved backbone to main market leaders; but today where the importance of internet research has gone high, there many of us, who are still unaware with its certain beneficial and vital concepts, out of which "Deep/Hidden Web" is the one.

It is not wrong to say that in today’s market if you are not able to make deep/hidden web as a part of your daily internet research, then you are really missing with some of important information and data, which could surprise you.

Avoiding this part of web means you are loosing some real gold coins. Yes!! That’s true; to explain you with this concept, let’s consider Internet as a vast sea. Where everyday you go for fishing (fishing = internet research).

This Sea (Internet) is full of variety of fishes (Web Data), out of which some have really high price in the market, whereas others have normal or no value. Now most of the times you tend to catch whatever comes in the fishing net and every time you end up catching lots of fishes; but only with normal or no price in the market. after trying few more times but gaining no luck over high value fishes, you end up your research assuming to catch such high value fishes you may need some professional tools or help and you come back to shore with the ship full of fishes which are good for nothing.

Similar case is with the Internet research. Every time you do internet research via search engines, typically Google; you just end up gathering information and data, which is either part of personal Blogs or doesn’t have any head and mouth; (means does not have any genuine identity, which can validate the sources of information). And after gathering lot of wasteful data & information, you end up research assuming, such data & information either is not available or you may need some professional help. And then Internet Research/Research Analysts/Market Research agencies take over their place.

But once you’ll be aware with the path of deep/hidden we, then you can get access to some really valuable information & data which you can never find via any search engines. And so far if you haven’t tried accessing deep web, then it would be not wrong to say that till now you may have built several opinions regarding unavailability of certain data and information over internet. If this is the case then hidden/deep web can breakdown such opinions in to pieces.

So let me give you little introduction about the deep web and what it can do for you.

What is Deep/Hidden Web? Is it something really hidden in the internet? If yes then why? If no then why it is called so? What all comes under this part of web etc.

Let’s try to cover all these aspects in short brief: So far our understanding about deep/hidden web revolves in our blogs, discussions or forums; however the fact is that even till now major chunk of internet & market researcher avoid going in to this part of web; because the actual simplified solutions to this concept has not been put in place, resulting even after knowing about the unlimited number of opportunities, we are not able to make it as our daily part of life.

To give you the most shortest description about the deep or invisible web, let me tell you that this part of web is never hidden or invisible; but it is just settled little deeper in internet, and has not been covered (indexed) by search engines & that’s why you cannot access such information or data via any search engine.

Deep/Hidden Web Definition by Wikipedia:

"The Deep Web (also called Deepnet, the invisible Web, DarkNet, Undernet or the hidden Web) refers to World Wide Web content that is not part of the Surface Web, which is indexed by standard search engines."

Let’s look in to some points which can make us aware with the real value of Deep/Hidden web.

1. Public information on the deep Web is currently 400 to 550 times larger than the commonly defined World Wide Web.

2. The deep Web contains 7,500 terabytes of information compared to nineteen terabytes of information in the surface Web.

3. The deep Web contains nearly 550 billion individual documents compared to the one billion of the surface Web.

4. More than 200,000 deep Web sites presently exist.

5. Sixty of the largest deep-Web sites collectively contain about 750 terabytes of information -- sufficient by themselves to exceed the size of the surface Web forty times.

6. On average, deep Web sites receive fifty per cent greater monthly traffic than surface sites and are more highly linked to than surface sites; however, the typical (median)

7. The deep Web is the largest growing category of new information on the Internet.

8. Deep Web sites tend to be narrower, with deeper content, than conventional surface sites.

9. Total quality content of the deep Web is 1,000 to 2,000 times greater than that of the surface Web.

10. Deep Web content is highly relevant to every information need, market, and domain.

11. More than half of the deep Web content resides in topic-specific databases.

12. A full ninety-five per cent of the deep Web is publicly accessible information -- not subject to fees or subscriptions.

Now the question comes here is "How Invisible web came in to place & what all it includes"?

Whenever we upload any type of information or data to internet, it could be anything like images, movies, documents, reports etc. for any purpose: "Personal, Official, Sharing, Learning and Business". Via any source: "Website, Blogs and Forums" becomes the part of web database.

In order to provide access of this data to people "Search Engines" comes in to place, search engines keep on indexing web data based on certain parameters like "Keywords, Categories, Tags" etc.. (Indexing is a procedure of cover data by search engines); so whatever data and information has been indexed by search engines; would be available for you during research.

But do you know, Internet database is so huge that so far search engines are only able to cover 20% of it, which means 80% of valuable information and data is still remained untouched on web surface.

Now apart from the huge size of internet database, there are several other reasons that many times, search engines fails to index important and valuable web data.

Some of the reasons are listed below:

*The Contents of Searchable Databases: When you search in a library catalog, article database, statistical database, etc., the results are generated "on the fly" in answer to your search. Because the crawler programs cannot type or think, they cannot enter passwords on a login screen or keywords in a search box. Thus, these databases must be searched separately.

*A special case: Google Scholar is part of the public or visible web. It contains citations to journal articles and other publications, with links to publishers or other sources where one can try to access the full text of the items. This is convenient, but results in Google Scholar are only a small fraction of all the scholarly publications that exist online. Much more - including most of the full text - is available through article databases that are part of the invisible web. The UC Berkeley Library subscribes to over 200 of these, accessible to our students, faculty, staff, and on-campus visitors through our Find Articles page.

*Excluded Pages: Search engine companies exclude some types of pages by policy, to avoid cluttering their databases with unwanted content.

*Dynamically generated pages of little value beyond single use: Think of the billions of possible web pages generated by searches for books in library catalogs, public-record databases, etc. Each of these is created in response to a specific need. Search engines do not want all these pages in their web databases, since they generally are not of broad interest.

*Pages deliberately excluded by their owners: A web page creator who does not want his/her page showing up in search engines can insert special "meta tags" that will not display on the screen, but will cause most search engines' crawlers to avoid the page.

So how you can get access to this important part of web and you can make Deep/Hidden web as a part of your daily internet research?

Well the solution lies in using deep/hidden search sources apart from normal search engines; it can be tough job, as search engines like Google is moreover a comfort zone for people and it is not easy to get habitual to other searchable resources which are not as friendly as Google. But to achieve the expected research results, you have to come out of search engines boundaries.

There are number of Deep/Hidden web resources available online, out of which few are quite useful. Some of the common tools you can use to access deep/hidden web are: completeplanet.com; infoplease.com; deeppeep.org; incywincy.com; fazzle.com; turbo10.com; infomine.com; etc..

Remember the tact lies in making these resources as a part of your daily web research; as we do in search engines and once you’ll start understanding each source individually; then Hidden web will remain no more hidden to you.
