What is a Hyperlink ?
Known as “link” for short, a hyperlink is a word or phrase which is clickable and takes the visitor to another Web page. This page can be within the same site or on a completely different site. Instead of a full URL string, a word or phrase is typically displayed in the body copy for the linked page (see “anchor text”), which can bring both reader and SEO benefits.
A hyperlink is a word, phrase, or image that you may click on to jump to a new document or a new section within the current document. They are found in nearly all Web pages, allowing users to click their way from page to page. Text hyperlinks are often blue and underlined, but don’t have to be. When you move the cursor over a hyperlink, whether it is text or an image, the arrow should change to a small hand pointing at the link. When you click it, a new page or place in the current page will open.
They are often referred to as just “links,” are common in Web pages, but can be found in other hypertext documents. These include certain encyclopedias, glossaries, dictionaries, and other references that use hyperlinks. The links act the same way as they do on the Web, allowing the user to jump from page to page. Basically, hyperlinks allow people to browse information at hyper speed.
The document containing a them are known as its source document. For example, in an online reference work such as MV3 Marketing, or Google, many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanisms such as tables of contents, footnotes, bibliographies, indexes, letters and glossaries.
In some hypertext hyperlinks can be bidirectional: they can be followed in two directions, so both ends act as anchors and as targets. More complex arrangements exist, such as many-to-many links.
Effect of Hyperlinks
The effect of following them may vary with the hypertext system and may sometimes depend on the link itself; for instance, on the World Wide Web most hyperlinks cause the target document to replace the document being displayed, but some are marked to cause the target document to open in a new window. Another possibility is transclusion, for which the link target is a document fragment that replaces the link anchor within the source document. Not only persons browsing the document follow hyperlinks. These hyperlinks may also be followed automatically by programs. A program that traverses the hypertext, following each hyperlink and gathering all the retrieved documents is known as a Web spider or crawler.
