Working with tags
We've mentioned the usage of product tags already in Chapter 2, Creating Your First Products. Using tags works exactly in the same way that you're used to when writing WordPress posts. So in here, we do not want to spend too much time in explaining the concept.
Just be aware that Product Tags and Tags for Posts are actually separated from each other. You may find the tags that you already used by navigating to Products | Tags in the menu on the left-hand side of your screen. Note that the tags that you entered during product creation appear here. Besides that, it's also possible to create a list of tags immediately in the Edit Product screen and use them later on. In general, when using a new tag, always ask yourself: Will this be a tag that I'll use more often?. If the answer is yes, go ahead and use it. If the answer is no, then it's better not to create that tag.
