Tag, your it! Tags are the short, one or two word, descriptors that you can attach to your bookmarks on del.icio.us , your images on Flickr , videos in YouTube , audio at Last.fm and to blog posts appearing in Technorati . (Popular social/bookmarking Web 2.0 sites). Tags can be used to help direct others with similar interests to your products and services. As the Web evolves, it will become increasingly important for marketers to learn how to harness the power of tags.
