The tags in WordPress play an important role on your blog. Tags are sometimes featured within a theme and many bloggers like to use “tag clouds” in their WordPress sidebar widgets.

Tags are one word descriptions of the topics or subjects covered in the post. Posts may be catagorized according to the tags found in them to help readers find related content on your site.

This video by “webservicesfhnt” sums everything up pretty well in a nice short video that runs just over 2 minutes in total. You will learn how to add tags and catagories to your WordPress blog.
