Why Page Rank is important?

Why is it important to have a better search engine result pages (SERP)?

Lets say, you are the owner of an online store that sells health product. Your price is competitive and your product is outstanding. But how can you attract customer to visit your site to purchase your prodcut? One thing you can do would be placing an ad to a heavy traffic search engine company that provides Cost-Per-Click (CPC) advertising program, like Google, Yahoo! or MSN. When a customer searching for a keyword related "health product", your ad will appear. If, for instance, the average cost per click is $0.5, to have 1000 visitors visit your web site would cost $500.

Now, what exactly is search engine result pages (SERP)?

When a visitor searching for a keyword, usually the visitor will only click onto the web sites display on the first page. If your website appears on the first page, then your SERP is 1. So, for instance, there are average 10,000 people search for the keyword "health product" in a month. If your SERP is 1, there's possibility that you would receive 10,000 extra visitors to your web site without any extra cost!

How to achieve a better search engine result pages (SERP)?

There are couple important factors. The first one is the keywords in your web site. If there isn't any description or keywords related to the product that you are selling, how can visitor find your web site through search engine? Another factor would be your site attribute. Usually, a popular web site would receive more inbound links from other web sites for references. Google designed an algorithm called PageRank to decide which web page is more important (more inbound links) than the other, which more likely to appear at the top of the search results.

Then how to receive a higher page rank (PR)?

Page Rank is like a voting system. When a web page link to another one, it "casted" a vote to the other web page. In theory, the more inbound links (votes) a page receive, the higher Page Rank the web page would have, but that is not exactly correct. Some Search Engine Optimization (SEO) company would offer, for a fee, to place your submitted site to hundreds of their web sites automatically. Those sites are considered to be "link farms", which are penalize by major search Engine Company, like Google, and will not help your web page to increase its Page Rank.

In a social bookmarking system, users save links to web pages that they want to remember and/or share. These bookmarks are usually public, and can be saved privately, shared only with specified people or groups, shared only inside certain networks, or another combination of public and private domains. The allowed people can usually view these bookmarks chronologically, by category or tags, or via a search engine.
