Here’s a description for a WordPress post tag titled “couple” in Traditional Chinese, incorporating some variations to suit potential contexts:

**Option 1: Simple and Straightforward**

* **Title:** 夫妻 (fū qī)
* **Description:** 指稱一對已婚伴侶，包括丈夫和妻子。可用於標記關於夫妻生活、關係的故事、照片、文章或產品。 (Refers to a married couple, including the husband and wife. Can be used to tag stories, photos, articles, or products related to married life and relationships.)

**Option 2: More Descriptive for Relationships**

* **Title:** 伴侶 (bàn lǚ)
* **Description:** 用於標記關於情侶、夫妻或其他形式的親密關係的內容。包含情侶、夫妻、或其他形式的伴侶關係的文章、故事、照片和相關產品。 (Used to tag content about couples, married couples, or other forms of intimate relationships. Includes articles, stories, photos, and related products about dating couples, married couples, or other forms of partnership.)

**Option 3: Focusing on Visual Tags (For a Photo Blog or Gallery)**

* **Title:** 雙人組合 (shuāng rén zǔ hé)
* **Description:** 用於標記展示兩個人一起的照片、插畫、或影片內容，包括情侶、夫妻、朋友、或其他關係。 (Used to tag photos, illustrations, or video content that feature two people together, including dating couples, married couples, friends or other relationships.)

**Option 4: Broad and inclusive**

* **Title:** 情侶/夫妻 (qíng lǚ / fū qī)
* **Description:** 用於標記關於戀愛中的情侶、已婚夫妻或任何親密關係的內容，包括照片、文章、購物推薦等。 (Used to tag content about dating couples, married couples, or any intimate relationship, including photos, articles, shopping recommendations, etc.)

**Key Considerations and Customization:**

* **Context of the Website:** The best description will depend on the overall theme and content of your website. Is it a blog about relationships, a wedding photography site, a lifestyle blog, or something else?
* **Target Audience:** Consider who your audience is. This will influence the word choice and level of formality.
* **SEO (Search Engine Optimization):** While not the primary focus here, using relevant keywords (like 夫妻, 伴侶, 情侶) in the description helps search engines understand what the tag represents.
* **Tagging Consistency:** It’s important to be consistent with your tagging throughout your site. Choose the most appropriate term and stick with it for similar content.
* **Multiple Languages** If your website supports multiple language, make sure you have the tag in the languages supported.
