Directories and Search Engines Defined The main characteristic of search engines is how they are indexing web pages as they go crawling the internet with an automated tool called a spider - This tool is no more than a browser like program following links from page to page, from one domain to an other.
Directories don't use spiders. They use real people called editors, to validate the quality and the relevance of your website. Because they are checked by a human being, the quality of a search in a directory - we are talking here about the main ones such as yahoo or Dmoz - is superior to the full automated search engine result page ( SERP ).
Probably because human being can not be replaced, search engines happen to visit directories to help their ranking algorithm. For example Google visits the open directory (Dmoz.org) on a regular basis. Search Engine Submission Gudie |
