ABSTRACT
A web page generally includes elements such as text, hyperlink, image, etc. Hyperlink represents a relationship between two web pages or just between sections of the same page. Understanding the hyperlink structure is fundamental to understanding the Web connectivity structure, because hyperlinks have been used in web indexing and information retrieval, as well as page ranking. If the Web were a car, hyperlinks would be the engine, because without them, we are not going anywhere. It can be concluded that search engines consider that any words used by other sites to describe a site is particularly relevant even if the keywords are not used in the backlinked site/page (the linked target destination). In other words, the foreign language text links allow the linked sites to have a chance to be retrieved as relevant results in response to a search query. Many search engines judge the linking page partly based on the quality of the linked page, and if many sites backlinking to a site use keywords in their link text, search engines will raise its ranking for those keywords. Ultimately, backlinks from popular websites with a higher ranking, have a higher weight then backlinks from smaller unknown websites.
