For search engines to increase their usefulness, their programmers must figure out how to dive into the deep Web and bring data to the surface. Keep reading to see more about what separates the surface and deep Web.Īnd the deep Web is only getting deeper and more complicated.
There are timed-access sites that no longer allow public views once a certain time limit has passed.Īll of those challenges, and a whole lot of others, make data much harder for search engines to find and index. Crawlers can't penetrate data that requires keyword searches on a single, specific Web site. There are private Web sites that require login passwords before you can access the contents. There are data incompatibilities and technical hurdles that complicate indexing efforts. Without it, the search engine would literally have to start searching billions of pages from scratch every time someone wanted information, a process that would be both unwieldy and exasperating.īut search engines can't see data stored to the deep Web. Each time you enter a keyword search, results appear almost instantly thanks to that index. This index or map is your key to finding specific data that's relevant to your needs. This process means using automated spiders or crawlers, which locate domains and then follow hyperlinks to other domains, like an arachnid following the silky tendrils of a web, in a sense creating a sprawling map of the Web. Search engines generally create an index of data by finding information that's stored on Web sites and other online resources. You can read all about it with How Internet Search Engines Work, but we'll give you a quick rundown here. To understand why so much information is out of sight of search engines, it helps to have a bit of background on searching technologies. Keep reading to find out how tangled our Web really becomes. Just as a search engine is simply scratching the surface of the Web, we're only getting started. For political dissidents and criminals alike, this kind of anonymity shows the immense power of the dark Web, enabling transfers of information, goods and services, legally or illegally, to the chagrin of the powers-that-be all over the world.

This software maintains the privacy of both the source and the destination of data and the people who access it. Often, these parts of the Web are accessible only if you use special browser software that helps to peel away the onion-like layers of the dark Web. In the dark Web, users really do intentionally bury data. There's a flip side of the deep Web that's a lot murkier - and, sometimes, darker - which is why it's also known as the dark web. It's just hard for current search engine technology to find and make sense of it.
This data isn't necessarily hidden on purpose. No one really knows how big the deep Web really is, but it's hundreds (or perhaps even thousands) of times bigger that the surface Web. The deep Web (also known as the undernet, invisible Web and hidden Web, among other monikers) consists of data that you won't locate with a simple Google search. As for the rest of it? Well, a lot of it's buried in what's called the deep Web.
