Search Engine Optimization for a website includes many things that must be done within the website itself including using selected keywords in the right places, proper site organization, and relevant content. But to get high rankings for your selected keywords in the search engines you must also have backlinks (links from other websites to your website).
One way to get some of those back links is to enter your business information (including your website URL or domain name) into various directories. Below is a list of several directories that you should add your business to for better SEO and page rankings.
