There are several benefits of making directory submissions:

• If you have a new website, directory submissions are a good way to get your site indexed and recognized by search engines.
  
• Directory submissions help search engines classify the theme of your site based on the category your site is listed under and the link/anchor text used.
  
• Directories provide one-way link to your site. Search engines value these links more than reciprocal links (links exchanged with other sites).
  
• You can control the anchor or link texts with which a directory links to your site, which will help your website rank high for searches made with those target terms
