A tag acts like a subject or category. A keyword is used to organize webpages and objects on the Internet. Each user "tags" a webpage or image using his/her own unique tag.
Tags help you find people that have something in common. For example, if you are looking for a yoga date, others may have tagged their profiles with the tags "yoga", "exercise", etc. The more searches there are for a particular tag, the bigger that tag is displayed. You can assign as many tags as you wish!
