**Recommendation:**

I recommend using **Option 2 or 3** as they provide more context of the purpose of the tag, it clarifies what kind of content will be available and for what type of users. Remember to choose the description that best reflects the overall tone and content of your WordPress site! Also, check the WordPress settings — some themes might display a limited number of characters for tag descriptions, so keep it concise if needed.
