A directory is an Index of websites compiled by people rather than a Crawler. Directories can be general or divided into specific categories and subcategories. A directory’s servers provide relevant lists of registered sites in response to user queries. Directory Registration is thus an important method for building inbound links and improving SEO performance. However, the decision to include a site and its directory rank or categorization is determined by directory editors rather than an Algorithm. Some directories accept free submissions while others require payment for listing.
