* **Audience:** Consider who you are writing for. If you’re targeting a general audience, keep the language simple and accessible.
* **Relevance:** Ensure the description accurately reflects the content that will be tagged with this tag.
* **Character Count** Ideally the text is short and concise. Usually less than 300 characters can achieve this.
