Basic Differences between Web Directories and Search Engines |
| Date Added: June 23, 2007 12:20:06 PM |
Search engines have a number of indices set up by robots or crawlers whereas web directories build up their indices through manual (human) editors, not automated ones. Numerous search engines and directories contain both a human generated index and a computer generated index, and are usually referred to as hybrids. Web directories, on the other hand, use human editors to review sites that are submitted for appraisal. Web directories, unlike search engines, organize their database using a hierarchical tree-structure. Another common yet un-noticed difference is that a directory usually lists websites (the root directory of a homepage or site) whereas a search engine is most likely to list web pages (eg: individual pages of a Web site). DMOZ, Gimpsy are the best examples of web directories while Google, AltaVista are perceived as the leading search engines. |
