'''DeepEnlazar linkingen profundidad''' (en españolinglés, ''enlazardeep en profundidadlinking''), en la [[World Wide Web]], consiste en hacer un [[hiperenlace]] que lleva a una página o imagen específica de otro [[sitio web]], en vez de llevar a la página principal de ese sitio. Los enlaces de ese tipo se denominan ''deep'enlaces linksprofundos''' (''enlacesdeep profundoslinks'').
== Ejemplo ==
Este enlace: http://es.wikipedia.org/wiki/Deep_linkingEnlace_profundo es un ejemplo de un enlace profundo. La URL contiene toda la información necesaria para llevar hasta un item particular, en este caso el artículo de [[Wikipedia]] en español sobre ''deep linking'', en vez de a la página principal en [http://www.wikipedia.org/ http://www.wikipedia.org/].
== Deep linking y HTTP ==
La tecnología que soporta la World Wide Web, el [[Hypertext Transfer Protocol]] (HTTP), no establece en realidad ninguna distinción entre enlaces "deep"profundos y otros enlaces—todos los enlaces son funcionalmente iguales. Esto es algo intencionado; uno de los propósitos explícitos de la Web es permitir a los autores enlazar a cualquier documento público de otro sitio. La posibilidad del llamado "deep" linking está, por lo tanto, presente en la tecnología Web del [[HTTP]] y del [[Uniform Resource Locator|URLsURL]] por defecto—aunque un sitio puede intentar restringir tales enlaces, hacerlo requiere un esfuerzo extra. De acuerdo con el Technical Architecture Group del [[World Wide Web Consortium]], "cualquier tentativa de prohibir la práctica del ''deep linking'' se basa en un malentendido sobre la tecnología, y amenaza con minar el funcionamiento de la Web como conjunto". Una forma de prevenir el ''deep linking'' es configurar el servidor web para comprobar la URL correspondiente usando un [[Rewrite engine]].<ref>{{Cita web

== Uso ==
Algunas páginas web comerciales critican que otras páginas hagan ''deep links'' a su contenido ya que eso supone saltarse los anuncios que aparecen en su página principal,

<!--passes off their content as that of the linker or, like ''[[The Wall Street Journal]]'', they charge users for permanently-valid links. Sometimes, deep linking has led to legal action such as in the 1997 case of [[Ticketmaster]] versus [[Microsoft]], where Microsoft deep-linked to Ticketmaster's site from its Sidewalk service. This case was settled when Microsoft and Ticketmaster arranged a licensing agreement. Ticketmaster later filed a similar case against Tickets.com, and the judge in this case ruled that such linking was legal as long as it was clear to whom the linked pages belonged .<ref>{{cite news| title=Attention Editors: Deep Link Away| first=Michelle| last=Finley| date=2000-03-30| publisher=Wired News| accessdate=2006-11-05}}</ref> The court also concluded that URL's themselves were not copyrightable, writing: "A URL is simply an address, open to the public, like the street address of a building, which, if known, can enable the user to reach the building. There is nothing sufficiently original to make the URL a copyrightable item, especially the way it is used. There appear to be no cases holding the URLs to be subject to copyright. On principle, they should not be."
==Deep linking and web technologies==
Websites which are built on web technologies such as [[Adobe flash|Adobe Flash]] and [[AJAX]] often do not support deep linking. This can result in usability problems for people visiting such websites. For example, visitors to these websites may be unable to save bookmarks to individual pages or [[State machine|states]] of the site, web browser forward and back buttons may not work as expected, and use of the browser's refresh button may return the user to the initial page.
However, this is not a fundamental limitation of these technologies. Well-known techniques, and libraries such as [[SWFAddress]], now exist that website creators using Flash or AJAX can use to provide deep linking to pages within their sites.<ref>{{cite web | url=http://www.adobe.com/devnet/flash/articles/deep_linking.html | title=Deep-linking to frames in Flash websites}}</ref><ref>{{cite web | url=http://www.asual.com/swfaddress/ | title=Deep Linking for Flash and Ajax}}</ref>
==Criticism==
Many critics charge that such sites simply want to establish policies that will "license" such links to the highest bidder. They argue that links are a fundamental part of "user-oriented" web browsing. Probably the earliest legal case arising out of deep-linking was the 1996 [[Scotland|Scottish]] case of ''Shetland Times vs Shetland News'' where the ''Times'' accused the ''News'' of appropriating stories on the Times' website as its own.
Critics say that the term 'deep linking' is unnecessary:
hyperlinking was always intended to refer to pages other than a publisher's front page, making deep linking nothing other than hyperlinking.
Some of those who find no fault with deep linking do find fault with [[inline linking]], the act of using media from another website directly within one's own website. It causes browsers to request the media directly from the original web server, using the creator's [[network bandwidth]] without any benefit to them. This is often described as ''stealing bandwidth.''
==Court rulings==
In the beginning of 2006 in a case between the search engine [[Bixee.com]] and job site Naukri.com, the [[Delhi High Court]] in [[India]] prohibited Bixee.com from deeplinking to Naukri.com.<ref>{{cite web

In December 2006, a Texas court ruled that linking by a [[motocross]] website to videos on a Texas-based motocross video production website did not constitute fair use. The court subsequently issued an injunction. <ref>{{cite web

In a February 2006-ruling, the [[Denmark|Danish]] Maritime and Commercial Court ([[Copenhagen]]) found systematic [[web crawler|crawling]], indexing and deeplinking by portal site ofir.dk of real estate site Home.dk not to conflict with Danish law or the database directive of the [[European Union]]. The Court even stated that search engines are desirable for the functioning of the Internet of today. And that one, when publishing information on the Internet, must assume—and accept—that search engines deep link to individual pages of one's website.<ref>{{cite web

==Opt out==
Web site owners wishing to prevent search engines from deep linking are able to use the existing [[Robots Exclusion Standard]] (<code>/robots.txt</code> file) to specify their desire or otherwise for their content to be indexed. Some feel that content owners who fail to provide a <code>/robots.txt</code> file are implying that they do not object to deep linking either by search engines or others who might link to their content. Others believe that content owners may be unaware of the Robots Exclusion Standard or may not use robots.txt for other reasons. Deep linking is also practiced outside the search engine context, so some participating in this debate question the relevance of the Robots Exclusion Standard to controversies about Deep Linking. The Robots Exclusion Standard does not programmatically enforce its directives so it does not prevent search engines and others who do not follow polite conventions from deep linking.
