Why are web directories so popular nowadays
Everyone is looking at getting their own directory but most webmasters still haven't considered what a good directory submission strategy can offer them.
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?
