* **Target Audience:** Consider the level of knowledge your audience has on the subject. A simpler description might be better for a general audience.
* **Keyword Density:** While the post_tag descriptions won’t massively impact SEO, you *should* consider including relevant keywords, such as “醫療保險” (health insurance) or “醫療開支” (medical spending).
* **Length:** WordPress limits the length of descriptions, so keep them concise yet informative.
* **Context:** Are you looking to provide basic information, or are you focusing on in-depth analysis?

Select the option that best suits your WordPress site’s needs. Good luck!
