NKZ directory is a human-edited web directory of quality websites. Our directory features thousands of categories for our visitors to browse. We adhere to strict standards when it comes to accepting submissions. We review every website that is submitted to the directory and acceptance is based on numerous factors. The website must be complete (not under construction), it must contain content that we feel is useful to our visitors and navigation should be easy. Submission details are also scrutinized. The title and description should be capitalized properly and free of errors in spelling and grammar. We feature both free and paid listing options for webmasters.
