Here are a few options for a WordPress post tag description, considering the meaning of “商用” (shāngyòng – commercial use) in Traditional Chinese, with varying degrees of detail and context:

**Option 1: Concise and General**

* **Description:** 適用於商業用途的。 (Applicable for commercial uses.)

**Option 2: Slightly More Explanatory**

* **Description:** 標示與商業目的、營利相關的內容。 (Indicates content related to commercial purposes and profit.)

**Option 3: Emphasizing Usage Rights**

* **Description:** 標註可供商業使用或具有商業用途的內容，請注意使用權及相關規定。 (Marks content that can be used or is used for commercial purposes. Please pay attention to usage rights and related regulations.)

**Option 4: Focusing on Content Types**

* **Description:** 包括產品、服務、宣傳、營銷等與商業相關的文章或主題。 (Includes articles or topics related to business, such as products, services, promotions, and marketing.)

**Option 5: A more formal and detailed approach (If your site uses that tone)**

* **Description:** 本標籤用於歸類與商業活動、商業產品、商業服務相關的內容。 涵蓋但不限於產品介紹、市場營銷、廣告宣傳、企業合作、以及其他旨在營利的相關資訊。 使用時請注意版權、授權、及相關法律規定。 (This tag is used to categorize content related to commercial activities, commercial products, and commercial services. This includes, but is not limited to, product introductions, marketing, advertising, corporate collaborations, and other profit-related information. Please pay attention to copyright, licensing, and relevant legal regulations when using.)

**Key Considerations When Choosing:**

* **Website Audience:** Consider who your target audience is and their level of understanding.
* **Website Tone:** The description should fit the overall tone and style of your website (formal, informal, etc.).
* **Content Focus:** Reflect the types of content you’ll be tagging with “商用”.
* **Usage Rights (Important):** Since “商用” implies commercial use, it’s crucial to mention something about usage rights, especially if your site includes downloadable assets or copyrighted material.

I recommend choosing the option that best suits your WordPress site’s specific needs and content. You can also adapt or combine elements from different options to create a description that’s perfect for your needs. Remember to put the chosen description into the *Description* field when you create or edit the tag in your WordPress Tags area.
