How big is the Deep Web? It is estimated to comprise 7,500 terabytes – although an exact size is not known, and the figures vary widely on this question. The magnitude, complexity and siloed nature of the Deep Web is a challenge for researchers. You cannot turn to one specific guide or one search engine to effectively access the vast range of information, data, files and communications that comprise it. The ubiquitous search engines index, manage and deliver results from the Surface web. These search results include links, data, information, reports, news, subject matter content and a large volume of advertising that is optimized to increase traffic to specific sites and support marketing and revenue focused objectives. On the other hand, the Deep Web – which is often misconstrued as a repository of dark and disreputable information [Note – it is not the Dark Web], has grown tremendously beyond that characterization to include significant content on a wide range of subject matters covering a broad swath of files and formats, databases, pay-walled content as well as communications and web traffic that is not otherwise accessible through the surface Web. This comprehensive multifaceted guide by Marcus Zillman providers you with an abundance of resources to learn about, search, apply appropriate privacy protections, and maximize your time and efforts to conduct effective and actionable research within the Deep Web.
