If you think that the World Wide Web is impressive, with its 1.25 billion websites and its 3.7 billion users, then get ready to think again. What we see on the web is just a fraction of what’s truly available, the proverbial tip of the iceberg.
Beneath the surface of the water lies the bulk of the iceberg, the deep web. It contains around five hundred times more information than the surface web and 550 billion individual documents – compared to the surface web’s 1 billion.
It’s estimated that over 200,000 deep web sites exist and that 95% of it is publically accessible, which means you won’t have to pay subscription fees or take out a membership to access it. It’s also constantly getting larger – in fact, it’s the most rapidly growing category for new content on the internet.
