I understand the concept of adding tags to a post. For each post you add your tags (keywords) to help search engines find that post.
What doesn't make sense to me is why I would want to add tags under Posts - Tags - Add New Tag. What is the purpose of adding tags there? I can't see the logic. I thought if I added tags there, when i went to a post, these tags would be available as a selection, but they are not.
Can anyone explain the logic of adding tags in this area. I have no idea what purpose they serve and where you can use them after you added them.
The blog I need help with is steveeyes.wordpress.com.
