With the popularity of blogs increasing every day, it's nearly impossible for a reader to know what blogs exist and where to find them all. This is where the encyclopedic power of the blog directory: it organizes and categorizes the thousands of blogs listed its database so readers can find your blog more easily. There are usually headings and all the person has to do to find your blog is point and click on a heading to find you. These blog directories also often have search engine boxes as well which is handy as many of the blog hosts don't. Many of them also allow visitors different ways of viewing the contents of the site - alphabetically, by date and so on.

Blog directories are generally free to the blogger, though they will often require you to feature a small, approved banner or a link is also placed on your site. Often your listing is not approved until the placement or link is in place. Depending on the directory this can take a few hours or a few weeks for them to approve.

To get listed in a blog catalog, visit them and submit your site, accurately describing your blog (an inaccurate description will result in less targeted traffic). Check their requirements for banners and be sure to use the link they generate for you - this will ensure you get credit if another blogger joins from your page. Most blog directories will require you to host their images on your own server space, so be sure to follow their directions. Stealing their bandwidth is a sure way to get de-listed in a hurry.

Some popular blog directories that you might want to check out are Blogadvance, Blogarama, Blogcrowd, Blogexchange, Blog Catalog, Get Blogs, Globe of Blogs, LS Blogs and Traffic Swarm.
