Deep Web Research and Discovery Resources 2014. Bots, Blogs and News Aggregators ( is a keynote presentation that I have been delivering over the last several years, and much of my information comes from the extensive research that I have completed over this time into the "invisible" or what I like to call the "deep" web.
The Deep Web covers in the vicinity of trillions upon trillions of pages of information located through the world wide web in various files and formats that the current search engines on the Internet either cannot find or have difficulty accessing. The current search engines find hundreds of billions of pages at the present time of this writing. In the last several years, some of the more comprehensive search engines have written algorithms to search the deeper portions of the world wide web by attempting to find files such as .pdf, .doc, .xls, ppt, .ps. and others.
This Deep Web Research and Discovery Resources 2014 report and guide is divided into the following sections: Academic and Scholar Search Engines and Bot. The Ultimate Guide to the Invisible Web. Search engines are, in a sense, the heartbeat of the internet; “Googling” has become a part of everyday speech and is even recognized by Merriam-Webster as a grammatically correct verb.

"As much as 90 percent of the internet is only accessible through deb web websites. " So where’s the rest? So what is the Deep Web, exactly? Search Engines and the Surface Web Understanding how surface pages are indexed by search engines can help you understand what the Deep Web is all about. How is the Deep Web Invisible to Search Engines? Reasons a Page is Invisible Art. The Invisible Web: A Beginners Guide to the Web You Don't See. By Wendy Boswell Updated June 02, 2016.
What is the Invisible Web? The term "invisible web" mainly refers to the vast repository of information that search engines and directories don't have direct access to, like databases. Unlike pages on the visible Web (that is, the Web that you can access from search engines and directories), information in databases is generally inaccessible to the software spiders and crawlers that create search engine indexes. How Big is the Invisible Web? The Invisible Web is estimated to be literally thousands of times larger than the Web content found with general search engine queries. The major search engines - Google, Yahoo, Bing - don't bring back all the "hidden" content in a typical search, simply because they can't see that content without specialized search parameters and/or search expertise. continue reading below our video.
