Here are a few options for the description of the WordPress post tag “來源證明” (Source Certification/Proof of Origin) in Traditional Chinese, ranging in formality and specificity:

**Option 1 (Concise and General):**

> 標記與文件、物品或資訊來源相關的帖子。 涵蓋了用於驗證物品或資訊真實性的資訊。

> *Translation: Tags posts related to the source of a document, item, or information. Covers information used to verify the authenticity of an item or information.*

**Option 2 (More Descriptive and Practical):**

> 涵蓋有關如何驗證產品、文件或資訊來源的帖子。這可能包括正品聲明、證明文件、產地證明等等。 幫助您了解所接觸的物品或資訊的真實性。

> *Translation: Covers posts about how to verify the source of a product, document, or piece of information. This may include declarations of authenticity, supporting documentation, certificates of origin, and more. Helps you understand the authenticity of the items or information you encounter.*

**Option 3 (Focused on Specific Use Cases – Example for Product Authentication):**

> 標記產品來源的帖子。 查看產品真實性，查閱製造商提供的證明、防偽標籤或其他驗證方法。 有助於確保您購買的是正品。

> *Translation: Tags posts regarding the source of a product. Review the authenticity of products, consult the manufacturer’s certifications, anti-counterfeiting labels, or other verification methods. Helps to ensure you are purchasing authentic goods.*

**Option 4 (Formal and Legalistic):**

> 標記與資訊、產品及其他資產的原始出處證明相關的帖子。 包括原始文件、授權書、產地證明及其他確立所有權或真實性的證明材料。

> *Translation: Tags posts related to the proof of origin of information, products, and other assets. Includes original documents, authorizations, certificates of origin, and other supporting materials that establish ownership or authenticity.*

**How to choose which description is best:**

* **Consider your audience:** Who are you writing for? A general audience? A specific group of collectors? A legal or academic audience?
* **Context of your website:** What kind of information do you primarily publish?
* **Desired level of detail:** How specific do you want to be in the description?

**Recommendation:**

I recommend **Option 2** if you’re aiming for a general, informative description that applies to a wide range of content. However, tailor it based on your specific website’s focus. For example, if you regularly discuss authenticating luxury goods, use Option 3. If you deal with legal information, Option 4 may be more suitable.

Remember to enter the description directly into the ‘Description’ field in your WordPress tag settings when creating or editing the “來源證明” tag. This helps with SEO and provides context for your readers.
