* **Audience:** Consider your target audience when picking a description. A more general audience appreciates options 1, 2 and 4. Option 3 appeals to a more tech-savvy user
* **Brevity:** WordPress gives you some character limit so keep it concise yet informative.
* **Clarity:** The most important thing is to be clear about what the tag represents.
