Why use a search engine? It is physically impossible to search and examine all of the information on the internet. Search engines help you sift through and find the information you need! Search engines give results based on How many times your keywords appear. Are there keywords in the title? What pages are linked to the site it is suggesting? Popularity of site (how many times the link has been selected). Wading Through the Web Different Types of Search Engines Why do Google and Yahoo! display different sites for the same word?
