Question: What are blog tags?

Answer: Blog tags are keywords that you can use to help users find your blog. When you are keying in a blog, you can either click on an existing 'tag' (keyword) or type in a new one if the most appropriate one is not there. The tags can be thought of as categories, in a way, because if a reader happens to click on the tag, then all blogs will that tag will be displayed. But they also help in searches, and they are helpful on search engines like Google. If you don't use them, no harm will come. However, it keeps the blogs more organized.
