Directory submission is most important in SEO because you will get one way back link to your site and it is free of cost. When Google give results of certain query it first look into directories so it increase your website reputation in search engines.
A web directory or link directory is a directory on the world wide web. It specializes in linking to other website and catagarizing those links. A web directory is not a search engine and does not display lists of web pages based on keywords instead, it lists web sites by category and subcategory. Most web directory entries are also not found by web crawlers but by humans. The categorization is usually based on the whole web site rather than one page or a set of keywords, and sites are often limited to inclusion in only a few categories. Web directories often allow site owners to submit their site for inclusion, and have editors review submissions for fitness.
directories are the websites which are ranked at a high Position and use your contents developing their site. so after that ultimately your site is view at a height position due to their rank.
