What is the dark web?
What the dark web is, what people use it for, how much of the internet it really is, and why no search engine can promise complete coverage of it.

What is the dark web?
Dark web commonly describes services accessed through particular overlay networks rather than ordinary public-web addressing alone. Tor onion services are one example. A page being absent from a search engine does not automatically make it an onion service.
Why do people use the dark web?
People use onion services for private communication and for publishing where ordinary access may be restricted, and Tor's own documentation describes those uses. Journalists, their sources and readers under network censorship are the cases most often given. The technology does not tell you whether a particular publisher is honest, a claim is accurate or a service is appropriate for your task, so a lawful purpose for the network says nothing about any individual site running on it.
How much of the internet is the dark web?
No one can give you a trustworthy figure, and the percentages repeated in popular articles rarely survive a look at their method. A share needs a defined denominator, a way to count services that are deliberately unlisted, and a date on which the count was taken. This guide does not publish a number because it cannot support one. If you are writing up research, state what you actually measured, such as how many sources a named index returned on a named date, and leave the global proportion recorded as unknown.
When was the dark web created?
There is no single creation date, because the dark web is an informal label rather than a product with a launch. The technology underneath it does have a documented history. The Tor Project records that in 1995 David Goldschlag, Michael G. Reed and Paul Syverson began the onion routing work at the U.S. Naval Research Laboratory, that the Tor network was initially deployed in October 2002 with its code released under a free and open software license, and that the Tor Project, Inc. was founded in 2006 to maintain Tor's development. Those dates describe the network. They do not date any particular site published on it.
Why search is incomplete
Discovery depends on known links, permitted indexing, reachability and freshness. Private or undiscovered services are not unlocked by a search query. This installation's enabled-source notice describes its actual coverage.
A useful way to classify a source
Ask three questions before choosing a tool: how do I reach the source, am I authorized to read it, and what evidence does it contain? Those questions describe different properties. A public onion publication may be reachable through Tor but absent from the particular index you searched. An ordinary website may require an account even though its homepage appears in Google. Neither situation can be resolved by asking an AI model to search harder. For example, a question about how onion addressing works is usually best answered by the Tor Project documentation. Searching an unknown forum for the same explanation adds uncertainty about authorship without necessarily adding useful evidence. Choose the source for its relationship to the question, rather than because its address sounds more exclusive.
What is the dark web used for?
Tor describes uses for private communication and publishing, including making information available where access may be restricted. These are uses of a network technology; they are not a statement about every site on that network. Evaluate the actual publisher and requested action. Reading a public technical explanation, submitting a confidential report and downloading an unknown file are different tasks and should not inherit the same trust decision. A good research note identifies which task was performed. Write “I reviewed this public document” rather than “I investigated the entire dark web.” That distinction makes the work easier for another person to check.
How much can a search result establish?
A result can establish that a particular source was found by a particular system at a particular time. To support a broader conclusion, inspect the passage and the source coverage. “No matching result” is a bounded observation, not proof that a topic is absent everywhere. If the question concerns a current event, seek a dated primary statement and preserve any uncertainty about when it was last checked. Start with the source coverage page before interpreting an empty search.
