Catalog
Web catalogs also called database or branch directory. These pages contain groups organized by addresses of other websites. Here, you can receive contents similar to a search engine according to specific criteria. The results of these queries are displayed in a list of links. Unlike a search engine is the work of the sighting, order and cataloging of Internet addresses made by editors. The labor-intensive maintenance of the catalog is in many cases with costs. For the search engine optimized care of the own website, it is of advantage to be listed in one or more catalogs. To calculate the link popularity also entries in certain web directories are consulted. The entry in the Open Directory Project is free, as there are voluntary editors.
