* **Why it’s good:** Adds a little more context, specifying the types of offerings this tag might be associated with. It also clarifies the meaning of “免年費” a bit more. Good for a more financially literate audience.

**Option 3 (Focus on Benefit):**

* **Translation:** Selected offers of free annual fees, helping you save on the yearly cost of owning products or services. Enjoy easily, without wasting money!
* **Why it’s good:** Highlights the benefit of the tag (saving money). Use a more promotional tone by including “輕鬆享受” (enjoy easily). Good for a broader audience, emphasizing the value proposition.

**Option 4 (For SEO purposes):**

**Which option to choose depends on your target audience and the overall tone of your website. If you are catering to a general audience, Options 1 or 3 are great. If your site is about finance, Option 2 might be suitable.**

**How to Implement in WordPress:**

1. **In your WordPress Admin panel:** Go to “Posts” -> “Tags”. (Or “文章” -> “標籤” if your WordPress is in Chinese.)
2. **Create a New Tag:** Enter “免年費” (or “Free Annual Fees” if your WordPress is in English) in the “Name” field.
3. **Enter one of the descriptions above in the “Description” field.**
4. **Add any relevant “Slug” (the URL-friendly version of the tag name).”** WordPress usually automatically generates one, but you can customize it. A good slug in this case would be `mian-nian-fei`.
5. **Click “Add New Tag” (或 添加新标签)。**
