Search Engines

The Internet is expanding at the rate of 20% each year and there are currently over 3 billion webpages indexed by Google.com. The vast collection of web sites and pages are often referred to as the "Web."

Finding information on the web can be daunting, particularly if you do not know the web address (URL) of the site you are looking for. As a result, many search engines have been created to index the websites around the globe. Yahoo initially offered indexes to websites, by manually adding links pointing to other websites into their database.

The proliferation of websites has made the manual task of adding and updating sites very time-consuming and difficult, which led to the rise of search engines such as Google. Google, with its intelligent and automatic webpage indexing techniques, offers a large database of websites that people commonly use to search for sites of interest.
