* **Consider your blog’s focus:** If your blog is focused on health, Option 2 or 3 is a good choice. If it’s more general, Option 1 will be sufficient.
* **Optimize for search engines:** Option 4 uses keywords, which can help with search engine optimization (SEO).
* **Keep it concise:** WordPress often displays only a snippet, so shorter descriptions are better.

When adding the description within WordPress, you’ll usually find a field for “Description” when you’re editing the tag in your admin dashboard (under “Tags” in the “Posts” section). Remember to save your changes!
