* **Your Blog’s Focus:** Are you highlighting value, or are you doing more technical reviews?
* **Keyword Usage:** While not the primary focus, consider including relevant keywords like “軟體 (ruǎnjiàn – software)”, “付費 (fùfèi – paid)”, “商業軟體 (shāngyè ruǎnjiàn – commercial software)”, “訂閱 (dìngxùn – subscription)” if appropriate.
* **Brevity:** Keep it concise and easy to understand. WordPress tag descriptions aren’t meant to be long.
* **Tone:** Adjust the tone to match your blog’s overall voice.

Choose the description that best fits your blog’s style and goals. You can also customize these examples to fit your specific needs. Good luck!
