Evaluating web sites
Anyone can make a Web site-- it's simple that many kids do it. Separating the quality, trustworthy sites from the rest isn't so easy. So how do you tell the good from the bad. First, you need to understand your search results.
It takes a Web-savvy eye to select the best sites from the search results. Keep these important factors in mind:
*The owners of a Web site write the brief description you see in the search results.
*The order in which the results appear is based primarily on relevancy, but many companies and others pay search to have their site appear above relevancy-rated results.

Authorit,Accuracy, objectivity, Currency, Coverage, Privacy
