What Is Deep Linking?
Deep linking is the operation to insert a page of a website a link (hyperlink) to an internal page of a different site. The term literally means “deep link”, indicating precisely which descends deep into the remote site and can therefore also be translated as direct connection (as an “around” the front page of the site and all those in between). By contrast, sometimes the connection to the first page (home page) is another site that links surface.
Types Of Links
The HTTP protocol, mechanism of transfer of web resources, has no concept of the structure of a site, it is just a conceptualization of the human user, also related to the fact that very often those who manage pages using a single server. For HTTP, all resources are accessible via URLs. For HTTP/1.0, there was even the name of the site, since the protocol was limited to a connection to the IP address corresponding to the 1.1 version has instead made it necessary to indicate the ‘host “to connect to.
A link on a Web page is simply a URL, which may point to different resources of the same or other sites:
- The so-called homepage of the site, i.e., the default page provided by the web server in the absence of further clarification;
- To a specific page of the site, specifying the path and file name;
- To a specific section of a page of a site, separating the string of parameters with the “?”, And separate parameters together with the character “&”.
All mechanisms are explicitly exposed links provided by the standards of the World Wide Web, born in science and therefore extremely liberal in providing for the possibility of linking records of different origins, but with the evolution hobbies, business and technology of the WWW, are gradually came into conflict with the intentions of some webmasters:
- The introduction of the “frame”, now being threatened with extinction, has made the text as a collection of independent pages within a “frame”, making difficult the recognition of the context from which the pages themselves;
- Particularly in commercial sites, corporate image makers tend to not like you go directly to the inside pages of a site full of jumping the homepage banner advertisements or notices that contain potentially important;
- If a site changes its internal structure, the link may point to a page that no longer exists;
- Many sites are designed, for reasons of an aesthetic nature or content organization, navigation path for a drive. For example, designers often draw up pages very short, for reasons of legibility of elegance, with the result that documents of a certain length must be divided into multiple pages to read in order;
- Many sites are now managed by applications which provide the look and content of pages based on factors quotas (user logged on, the date or hour, results of a search, etc.), with the result that a URL does not match necessarily always the same content.
Therefore, it was gradually created the “problem of deep linking”, which covers both:
- Those who create web sites and, for some of the reasons, want their own internal pages that are not linked directly,
- Or who, by the opposite point of view, would be point specifically to the content of other sites without success.
Consider a site that contains technical material on a program in which the links should lead directly to specific pages of the software manufacturer and not to his homepage.
