Tags, also known as keywords, help visitors find the content they're looking for more quickly. That means that they also help YOU promote your content and make sure it gets seen by the right people as often as possible. You should add tags to your item that relate to important elements within it; size, color, who it's for, what kind of craft it is, etc. So if you're writing an article or how-to about knitting a yellow baby blanket, you should include the tags: yellow, baby, knitting, blanket, gift, etc! Don't overdo it! You shouldn't use more than around five tags for most stories. Remember to keep it relevant and appropriate.
