Directories are like online libraries for websites. They are themselves websites that categorize and list other websites, based on many factors depending on the directory.
Getting listed in a directory can boost your site's visibility with a valuable backlink. DMoz is the web's largest and most popular directory. Smaller, niche-based directories can be powerful as well. For instance, if your business is an art gallery, try searching the web for art-based directories.
Article databases like EzineArticles.com and Squidoo.com have loads of articles written on a variety of topics. Write a few quality articles relating to your website's niche, and include some backlinks to your website. We suggest using Anchor Text (see below) when linking i.e. instead of merely linking using the URL or the words 'click here', use relevant keyword phrases. For example, a person who has a search engine optimization website might do well to use "SEO services" rather than something like "click here now."
Same concept as the article submissions, only the content must be announcing something news-worthy related to your website, or industry. A product release, a special event or promotion, a new partnership, etc. are all great fodder for press releases. Include backlinks to your website, again using 'anchor text' where possible. PRWeband 24-7 Press Release are great PR sites to use. They cost money, but can lead to valuable links.
Getting involved in an online community related to your niche can lead to many link-building opportunities. Blogs, forums and social media sites are full of people interested in the same topics as you, looking to connect and form business relationships. Join as many of these groups as you can, and make yourself known as someone offering value to the community. Guest blogging and affiliate marketing are two great ways to gain back-links to your Wix website.
