Web directories are organized Web site listings put together by human editors and reviewers, whereas search engine listings are put together by automated systems and lack a navigable structure. Much of the confusion stems from the various hybrid models that have developed over time, as search engines have incorporated directory features to assist with issues such as categorization and website quality.
There are advantages and drawbacks to using a Web directory as opposed to a search engine. One vehicle may be better suited to certain types of searches than the other. Web Directories place an emphasis on linking to site home pages and try to minimize deep linking. This makes directories more useful for finding sites instead of individual pages. Some directories attempt to solve this shortcoming by partnering with a search engine for supplemental listings feature.
The most important web directory advantage or benefit of listing with several directories is ‘link building’. The more directories you are listed with the higher are your chances for a better ranking in the search engine result. Although search engine provide less quality traffic, it is still as we all know very much important because the number of users searching information via a search engine is higher than specific directories.
