**How to Choose:**

* **Your Blog’s Focus:** If your blog covers a specific set of genres, choose an option that reflects that.
* **Target Audience:** Consider what kind of language will resonate best with your readers.
* **SEO Goals:** If you want to improve search engine rankings, the keyword-focused option (Option 4) can be helpful.
* **Space limitations:** Take a look at where the description will appear to see if you have space limits on the length of the description.

**In WordPress:**

When adding these descriptions in WordPress, find the tag in your backend and paste one into the “Description” field. This should be found under “Tags” within the “Posts” section or a similar location depending on your WordPress theme.

Make sure to use the appropriate character set (Traditional Chinese) when entering the text. Good luck with your blog!
