The Invisible Web is the part of the World Wide Web, which is not indexable by search engines and is therefore invisible. In contrast to the Surface Web, the Invisible Web consists of data and information that cannot be searched with search engines for various reasons. Users cannot access this information by using traditional search engines. Non-indexed websites, apps, and resources include protected information in the areas of email, online banking, specialized databases, and other paid services, for example, through a paywall. In addition, there are non-linked and password-protected websites as well as media types and archives which cannot be crawled with current search engine technology.
