Originally there were two kinds of search services on the web: Engines and Directories. Index maintain by search are called Web Directories. Web directories are hierarchical define that particular databases with references to websites. The websites that are handpicked by living human beings and classified according to the rules of that particular search service. A directory basically a manual entry database system. We as the end user submitting our URL will supply the directory with all of the needed information during the submission process. At a minimum, this information includes URL title and a short summary of website. Rarely will the directory have any program capable of visiting our website, although a few directories do have a simple spider capable of verve a simple spider capable of verifying the URL we provided was a valid URL. While both classes of systems has elements in common, such as ability to search the data base, Boolean expressions and advanced features.
The primary action lies in how the two systems obtain their data. Once does it automatically (search engines) and the other does it manually (directories).There are many fantastically beautiful websites out there, which will never receive the exposure they deserve. Unlike a directory, the search engine only allows us to enter a URL for submission to their system. How a search engine indexes and summarizes our web page is entirely out of our control. In response to a query a search engine returns a ranked list of documents. If the query is broad (if it matches many documents) then the returned list is usually too long to view fully. Web directories returns more closer results although those results are very few in number. Using web directories there less chances of vocabulary mismatch as user no need to type only need to select any item or topic from given menu. People make mistakes in spelling all the time and often are unable to remember unfamiliar terms such as diseases, product codes and names in general. Web directory remove all these difficulties.
There are many websites available on web that still are not able to understand how important it is to get a listing in a web directory, as most of them are still lacking the information as to how these web directories can help them to generate a strong marketing structure. Mostly search engines are constantly catch new websites using web spiders which would be a popular web directory on the web to get new links and update the content for that directory.
