**Important Considerations when Choosing:**

* **Context:** Consider the nature of your blog and the types of articles you write. If you focus on a specific industry, a more targeted description might be suitable. If you cover many industries, a broader one is better.
* **WordPress Theme:** Some themes display tag descriptions prominently; others don’t. Adjust the length and detail accordingly.
* **SEO (Search Engine Optimization):** While tag descriptions have a limited impact on SEO, using relevant keywords can help. Consider including keywords like “產業” (chǎnyè – industry) and related terms.
* **Target Audience:** Use language that is clear and easily understood by your target audience.

When adding the description in WordPress, go to the Tag edit screen and look for the “Description” field. Paste your chosen description into that field. Remember to update the tag after you’ve added the description.
