Here are a few options for describing the WordPress post tag “商用不動產” (Business Real Estate) in Traditional Chinese, catering to different levels of detail and SEO considerations:

**Option 1: Concise & SEO-focused**

* **Pros:** Short, sweet, and to the point. Good for quick tagging and search engine optimization.
* **Cons:** Lacks detail.

**Option 2: Slightly More Detailed**

* **Pros:** More informative, giving a clearer understanding of the scope of the tag.
* **Cons:** Slightly longer, but still manageable for short descriptions.

**Option 3: Focused on Investment and Application**

* **Pros:** Good for attracting readers interested in investment or business opportunities. Provides a focus for content associated with the tag.
* **Cons:** Longer, but the added keywords are more relevant to an investor.

**Option 4: A Balanced Option**

**Recommendation:**

Choose the option that best aligns with the overall tone and purpose of your WordPress site and the content you plan to associate with it. For a general business real estate tag, **Option 2** or **Option 4** would likely be a good starting point. If you’re focusing on investment, **Option 3**. Finally, you can also adjust the English translation, or add one if needed.
