**Choosing the best option depends on the content of your blog posts:**

* If you focus on law and rights, Option 3 is the most appropriate.
* If you offer advice, Option 4 works very well.
* Option 1 is appropriate for a wider variety of content.

**Final Notes:**

* Remember to insert the chosen description into the “Description” field when creating or editing the tag in your WordPress admin panel.
* Consider your target audience when choosing the description. Simpler language is generally better for wider appeal.
* You can also customize these options further to fit the exact content you’ll be tagging. Good luck!
