Here are a few options for the description of the WordPress post tag “資料傳輸” (“Data Transfer”) in Traditional Chinese, ranging in length and specificity:

**Option 1: Concise & General**

* **Description:** 關於數據在不同裝置或系統間的移動與交換。 (About the movement and exchange of data between different devices or systems.)

**Option 2: Slightly More Detailed**

* **Description:** 涵蓋各種資料傳輸方法、協議、以及相關技術，例如文件分享、網絡傳輸、雲端儲存等。 (Covers various data transfer methods, protocols, and related technologies, such as file sharing, network transfers, cloud storage, etc.)

**How to Choose the Best Option:**

* **Consider your Target Audience:** Who are you writing for? Are they technical users, general users, or a mix?
* **What Content Will be Tagged?** What kind of posts will be using this tag? Will they be highly technical, or more casual?
* **WordPress SEO:** While tag *descriptions* don’t directly influence SEO as much as post content, a well-written description helps users and search engines understand the *scope* of the tag. Choose the description that best reflects this scope.

I recommend choosing **Option 2 or 3** as a good balance between comprehensiveness and usability. They are clear and suitable for a broad audience. Adjust the wording slightly to best suit the specific content you’re tagging. Remember to input this description into the “Description” field when you add/edit the tag in your WordPress admin panel.
