Search Engines on the Web

In class last week we discussed Search Engines. There are many different ones available to us on the internet. Search Engines are created by "spiders" or "crawlers". The advantages of them are that they usually have more hits, the disadvantages are that they are usually less relevant and their rankings may be biased. Some examples of some search engines are: Altavista.com, Google.com, Alltheweb.com, etc. Search Engine results are influenced by advertisers, payment for placement, and frequency of terms on a page. When I have a question on something or need to get research I go to a search engine and type in what I am looking for.
