**Key Considerations When Choosing:**

* **Your Blog’s Content:** Which option best reflects the general topics you cover related to the term “親密度”?
* **Audience Understanding:** Is your audience familiar with more nuanced descriptions, or do they prefer a simpler approach?
* **SEO (Search Engine Optimization):** Keywords can help search engines understand your post’s topic. Choose keywords specifically relevant to the content.

When setting the description in WordPress, you’ll usually find a field for this in the “Tag” or “Tags” interface, alongside where you enter the title of the tag (“親密度” in this case). Choose the description that best fits your needs! Then add one or more keywords, separating keywords with a comma.
