Here are a few description options for the WordPress post tag “首購” (meaning “first purchase” in Traditional Chinese), ranging from simple to slightly more descriptive, depending on your content and target audience:

**Option 1: Short & Sweet (Recommended for brevity)**

* **Description:** 首次購買優惠及相關資訊。 (First-time purchase promotions and related information.)

**Option 2: Slightly More Detailed**

* **Description:** 專為首次購物顧客提供的優惠、折扣、及使用指南。 (Special offers, discounts, and guides specifically for first-time buyers.)

**Option 3: Focusing on Specific Content**

* **Description (If the tag primarily concerns discounts):** 新客戶專屬折扣與首購優惠大公開！ (Exclusive discounts and first-time buyer promotions revealed!)
* **Description (If the tag primarily concerns specific products):** 適用於首次購買者的產品推荐、使用教學及相關資訊。 (Product recommendations, usage tutorials, and relevant information for first-time buyers.)

**Option 4: General and Broad (Suitable if the content varies)**

* **Description:** 關於首次購物的所有內容，包括優惠、指南、常見問題等。 (Everything about your first purchase, including promotions, guides, FAQs, etc.)

**Key Considerations When Choosing:**

* **Your Content:** What kind of posts are tagged with “首購”? Are they primarily about discounts, specific products, or a wider range of topics?
* **Your Audience:** Are you writing for a tech-savvy audience or one that might need a little more explanation?
* **Brevity:** WordPress tag descriptions should ideally be concise and to the point.

I recommend choosing the option that best reflects the type of content you associate with the “首購” tag. Option 1 or 2 are usually good starting points.
