# Tags & facets
There are 3 types of Facets to use:
1. Content (Exam, Module, Subject, Topic & Subtopic)
2. Skill
3. Difficulty
The most important ones on platform are Subject, Topic and Subtopic as these are the ones used to display breakdowns to students. This article won't go into the details of making tags so please see our question creation articles for guides on creating tags in quizzes. If you need to bulk update questions with tags, use the importer.
📍 Approved characters in tags: `!` `_` `(` `)` `<` `>` `.` `,` `+` `/` `:` `;`
Note any other characters in tags such as `&` will not be able to be created or imported

### 🏷 Tag manager
New tags will automatically be created and stored in the tag manager, or you can create tags here first by going to **Settings > Pages > Add Tag.** From the tag manager you can find the tag ID and label. You'll need the label to add tags to a spreadsheet or to questions in the builder. This is also where you'll assign facets to different tags
#### 📇 Labels
Capitals and spaces are accepted in tag label names. We recommend you keep the labels as short as possible so they display well on mixed screen sizes.
#### 👀 Visibility
Question tags do not show in attempts for exams and quizzes in timed or exam mode. They do show in practice mode as feedback is given after each question. Visibility refers to whether they are visible on the results (feedback) and insights page if these are configured for Students. New tags are visible to users on results pages by default. However, you may want to have tags that aren't visible to students. Change the visibility of a tag via the tag manager and tag editor. Note that faceted tags must be visible to students.
If a tag is faceted and you want to hide it from students, the facet must be removed first in order to update the visibility.
An example of a tag you may want to hide from users is if you're using one for management purposes eg a tag like 'Batch 1 June Import' to help with your internal management of question banks
### 📚 Facets
From the tag manager you can assign different facets to different tags. Choose from the following :
* **Content :** The content hierarchy looks like **Exam>Module>Subject>Topic>Subtopic**
* **Skill**
* **Difficulty**
Please see our facet best practices for more information and guidance on how to select facets for your tags. Use the chat function on platform to talk to an account manager who will make suggestions about how to order and facet your content
