**Which one to choose?**

Consider these factors when deciding:

* **Your target audience:** Who are you writing for? Are they health-conscious, concerned with quality, or just looking for basic information?
* **The context of the blog post:** What is the overall topic, and what are you trying to emphasize?
* **Available space:** WordPress allows for both titles and descriptions for tags. If space is limited, choose a concise option.

I recommend choosing the option that best reflects the content of your post and your target audience. For example, if your post focuses on the health benefits of pure water, choose Option 2. If it’s a general overview, Option 1 or 4 are perfectly fine.. You can always adjust the wording to better suit the specific post.
