1. Directory Text - Create a few different titles and descriptions for your site. Vary the word count, key phrases and your target audience in order to be considered for a variety of directories.
2. PageRank - Look for quality directories with a Google PageRank of 3 or better.
3. Update Your List - Constantly update your list of directories. This includes deleting old directories and updating changes in PageRank.
4. Comments - Create a comment column on your list of directories where you can note specific information about the directory. This is useful for niche or regional directories.
5. Save the Date - When you submit to a directory, record the date submitted. Knowing when you submitted lets you know when you can expect to be included. Most free directories have a waiting period of a few months.
