Back in 1995, I picked up a book titled, World Wide Web Directory. In the time that it took to create and publish this book, the number of websites had already grown by about 10. It was out of date within weeks and obsolete within months. It didnt take long to establish a demand for a dynamic directory and indexed search of the world wide web (WWW). This was the impetus for online search engines.
Search engines exist to help manage and organize massive amounts of information accessible over the Internet, which continually change on a minute-by-minute basis, so that website visitors can find exactly what they are looking for in the shortest amount of time and effort.
The leading search engines (Google, Yahoo®, and Live) have developed proprietary algorithms to rank, sort, prioritize, and determine which websites deliver the most relevant content for any given keyword phrase. They constantly tweak their algorithms to improve the accuracy of their search results and, at the same time, discourage search engine manipulation.
