There are lot of websites which are fully or partially clone of ODP (Open Directory Project).These websites or part section of websites, which are using ODP script to reformat the data on there site are useless and they have no original new contents. It is learnt that search engine specially Google is purging or banning such kind of sites. Why search engines are against Dmoz clone sites? Is the data in them not worthwhile or are they been misused by site owner's? We will try to find our reason, but before that let us first understand all about Dmoz Directory
What is Dmoz Directory (ODP)
The Open Directory Project is the largest, most comprehensive human-edited directory on the web. It is owned by "Time Warner" and constructed and maintained by a vast, global community of volunteer editors, and is truly unique in many ways. The Open Directory, also known as DMOZ (the domain name of ODP), is a large, categorized directory of websites and pages, which is staffed by volunteers. Every website and page that is added to the directory has to be manually reviewed before it is included. Since its index is manually constructed and edited, categorization and relevancy is superior to any other index of its kind and equally as unique, is the fact that this data is open and free to the public for replication. As of July 2005, ODP had about 4.6 million listings organized into over 580,000 categories derived from the contributions of some 69,000 editors.
