* **Target audience:** Consider who you are trying to reach. Do you want a simplified explanation or a more in-depth one?
* **Content of related posts:** The description should accurately reflect the content of the articles tagged with this term.
* **Keywords:** The descriptions are already good. You could add more keywords, but these are enough for this specific topic.
