**Important Considerations for WordPress:**

* **Character Limit:** WordPress itself sometimes limits the description field. Be mindful of this and tailor your description accordingly.
* **Keywords:** While descriptions aren’t used for keyword stuffing, try to include relevant terms (like “需求,” “必要,” “評估,” “決策”) to help with search visibility.
* **Consider the context:** How will the tag actually be displayed on your site? Will it be on a single tag page? In a list of tags? Your description should complement that display.
