Hi,
Not sure I understand your question. Note that meta-tags are different from “tags.” Meta-tags are words or phrases you add to the head section of an html page to provide info about the site to search engines. Tags, as used in wordpress blogs, are descriptive words that you add to your posts as a way of describing the content of the post.
For the Widget labeled “Tag Cloud,” when I add that widget to my sidebar, there’s nothing else (other than an optional title) to add to customize the widget; the tag cloud itself (which is just a way of displaying all of the tags that I have on all my posts) is created automatically and shows up in the sidebar on my site.
If your blog is new, and you have added meta-tags but haven’t added any tags to your posts, you’re not going to see any tags in your tag cloud.
