**Key Considerations When Choosing:**

* **Your Target Audience:** Who are you trying to reach with your posts? Are they tech enthusiasts, policymakers, or the general public? Tailor the description to their level of understanding.
* **The Type of Content:** Are you writing about technology, policy, specific examples, or all of the above? Reflect the primary focus of your posts.
* **Length:** WordPress post tag descriptions aren’t usually displayed in a highly prominent way. Choose a length that’s appropriate for the visual layout of your site.
* **Keywords:** While not as crucial as post titles or content, including relevant keywords (like 物聯網, 人工智能, 城市規劃, 交通運輸) within the description can help with SEO.

To use these in WordPress, select the tag in your WordPress admin panel and add the description to the text box labeled “Description.” Good luck!
