Search engines are algorithmic information retrieval systems that allow searching of massive web-based databases. A web search engine is designed to search for information on the World Wide Web and FTP servers. The search results are generally presented in a list of results and are often called hits. The information may consist of web pages, images, information and other types of files, such as:

  • Google;
  • Bing;
  • Yahoo;
  • AOL Search;
  • Ask Jeeves;
  • Excite;
  • Lycos; and
  • Alta Vista

Search Directories
Search directories are online resources, usually with extensive databases, that are used for searches and online marketing. Search directories provide different functionality than meta-search engines in that they are usually a compilation of specific searches, can have advertisements, news, and other services, and may have different specified categories for users to search URLs and links. Here is a list:

  • Yahoo Directory;
  • BOTW;
  • Jayde
  • LookSmart;
  • Open Directory Project (; and
  • Wikipedia

Information Aggregators
