Authoritative Links And Where Do You Get Them
Google attempts to quantify the authority of a web page through the use of PageRank. PageRank is Google's method for measuring the importance or authority of a web page. Authority on the web, authoritative links, and the importance of quality backlinks can be explained through the following analogy. If you needed an explanation, as to why you were experiencing intense pain in your side, you would trust the answer of one internal surgeon over the answers of 1,000 automobile factory workers. Just as you would trust the information of a surgeon, who is an authority on internal side pain, more than you would trust the information provided from 1,000 people's un-authoritative opinion, so do search engines "trust" links to your web page from authoritative sites more than they "trust" a large quantity of links to your page from sites that are seen as unimportant.
