**Choosing the best option:**

* **Consider your target audience:** Who will be reading your blog posts? A more technical audience might appreciate the keywords in Option 3. A general audience likely benefits more from Option 2 or 4.
* **What is the purpose of the tag group?** Is it primarily for internal organization, or do you want the description to show up in search results? If for search results, including keywords is generally a good idea (Option 3).
* **Length limits:** Ensure the WordPress theme allows you to enter the description on the tag page. Some themes may have character limits.

I recommend either **Option 2 or 3**. They’re informative without being overly verbose. You can add this in the tag description field when you edit the post tag in your WordPress admin panel.
