**Which to Choose:**

The best option depends on:

* **The general content of your blog:** Is it primarily about comparing offers, or is it more general advice-oriented?
* **Keyword strategy (SEO):** Do you want to focus on a specific benefit like cash back or bonus points?

Consider adding a specific keyword like “現金回饋 (cash back)” or “紅利點數 (bonus points)” depending on the focus of your content. For example, if your blog frequently covers good cash back offers, include “現金回饋” within the description.

I recommend picking the option that best reflects the type of content you’ll be tagging with “信用卡刷卡優惠”.
