This checklist of tagging criteria has been prepared in order to give a comprehensive idea on things to look out for when tagging. The tagging criteria has been categorized by priority to bring attention to the more important tags.
For your easy reference, common tags, along with links to relevant tag groups have been provided.
As the checklist is quite long, please take it easy when familiarizing yourself with this list. Begin with the more important tags at Level 0 (and all sub-levels), and then work your way upwards.
About Tagging Priorities
Lower level tags are essential tags. Images lacking lower level tags are considered insufficient for efficient cataloging and searching.
Higher level tags are extra tags which describe the more intricate details of an image, but are more difficult to apply correctly, usually due to potential for debate, or a higher requirement of knowledge of otherwise obscure topics such as memes.
Note to taggers: This checklist is still in a very early stage, You may help out in expanding this checklist. However, if any part of this list grows too large, please inform the forums about creating a tag_group. Remember to reference this tagging checklist!
Ignore, Do NOT Tag
Subjective tags that express opinions or subjective critique on images. Common examples are badass, cute, good, evil, moe, sexy and most other adjectives. A full list of known subjective tags may be found at Tag_group:Subjective.
Subjective themes, such as misleading thumbnails or lingerie ninja are also not to be tagged.
Subjective tags and themes best left as pools.
Very generic themes best left as multiple tags.
- Blondes in Bikini blonde_hair bikini
- Bloody Fighting: battle blood
- Izayoi Sakuya in lingerie: izayoi_sakuya lingerie
- Muscular Kirisame Marisa: kirisame_marisa muscle
- Portraits of Hatsune Miku: portrait hatsune_miku, solo hatsune_miku
Note that these searches are possible from a basic Member account, with a two-tag search limit, even if a little browsing may be required.
Priority: Level 0, Basic Identification
All posts MUST have these tags, if possible. These tags are responsible for making Danbooru minimally searchable, and allow content filtering for viewers who do not like sexual content, or images with commonly blacklisted tags.
- Artist (prefix with artist: when creating a new tag)
- If the artist does not currently have a tag on Danbooru, consider creating a new one. If you don't know how to read their name to create a tag, consider asking in the forum topic Artist tagging help, where someone is likely to help you come up with a name for the tag.
- Copyright (prefix with copyright: when creating a new tag)
- Character (prefix with character: when creating a new tag)
- Character lists from popular copyrights are available at tag_groups, in the Characters section.
- Use this tag for illustrations that feature characters that are not related to any kind of copyright.
- Frequently, these characters appear only in the one illustration, and will not have a name. In these cases, it isn't necessary to include character tags for them; the original tag is enough.
- Sometimes, such a character may become recurring, limited to a single artist, or multiple artists on a very small scale. (In this case, they may have names. Most such named original characters can be found in the list_of_original_characters.)
- Note: sexually_suggestive can carry a Safe rating.
- Spoilers (Important: apply if image is a potential spoiler)
Let's keep Danbooru a spoiler-free community.

- To be added only when a (fully translated, if necessary) commentary from the original artist is quoted in the comments of a post.

- absurdres (3200x2400 or larger)
- incredibly absurdres (any dimension above 10000)

- Memes, see tag_group:meme
- Artistic Technique, Method of Creation/Preparation
- Text and Languages
Priority: Level 4, Microscopic Details
These tags identify extremely minute details in the background, often missed by a glance. The importance of tagging these details may be under debate, as they can either make or break the searchability of our images depending on the situation.
- Characters that appear far in the background
- Characters which are only partially visible
- Characters whose point of view is the subject of the image
Please check if tags have been accidentally created, usually due to a spelling error or simply things like cultural differences between taggers. Such tags can be identified on the left side of a post's full view. If you see any tags with a count of exactly 1, those tags may have been accidentally created.
Different taggers may have different words to describe the same actions, objects and events. Familiarizing yourself with the tag_groups is particularly important to find out which tags Danbooru uses. If you have any issues, it will be best to consult the forums.
