* **Keywords:** Make sure the description includes relevant keywords like 電子書 (eBook), 閱讀 (reading), 閱讀器 (eReader), etc.
* **Target Audience:** Consider your target audience and their level of familiarity with eBooks when writing the description.
* **Consistency:** Make sure all of your tag descriptions have a consistent tone and focus.
* **Character Count:** WordPress may have limits. While WordPress doesn’t explicitly limit the description field in all cases, some themes or plugins might. Consider the impact it will have on the theme, and make sure it’s not too long.

Choose the option that best suits your needs and your blog’s content. You can always adjust it later! Good Luck!
