A blog directory is a list of blogs organized into a format that allows users to quickly find the information (in this case, a blog) they are looking for. In general, a blog directory, also known as a blog index, is organized alphabetically by keyword. However, a blog directory can be organized or categorized by any means that will make the blog list easier for the user to search. For example, many travel blog directories are organized by country. Blogwise.com is a popular blog directory that provides a blog index for nearly 38,000 blogs with another 1,700-plus blogs waiting to be approved.
