Explanation / Answer

Influential Algorithm in Business World

There was a time not too long ago when search engines battled it out for Internet supremacy. But along came Google and its innovative PageRank algorithm. Today, Google accounts for 66.7% of the U.S. market share in core search, followed by Microsoft (18.1%), Yahoo (11.2%), Ask (2.6%), and AOL (1.4%). Google now dominates the market to the point where we don't even question it anymore; for many of us, it's our primary avenue of entry into the Internet.

PageRank works in conjunction with automated programs called spiders or crawlers, and a large index of keywords and their locations. The algorithm works by evaluating the number and quality of links to a page to get a rough estimate of how important the website is. The basic idea is that the more important or worthwhile websites are likely to receive more links from other websites. It's basically a popularity contest. In addition to this, the PageRank algorithm considers the frequency and location of keywords within a web page and how long the web page has existed.
