deep link
deep link. Intellectual property. A webpage hyperlink that, when clicked, opens a page on another website other than that site’s home page. • Some plaintiffs have argued, with mixed success, that bypassing their home pages in this manner deprives them of advertising revenue. Deep-linking does not violate copyright if the portal provided does not copy any of the linked page’s content. And if there is no confusion about the source of the information, deep-linking does not constitute unfair competition.
