Tags are basically keywords you can use to describe posts, allowing you to easily search and explore posts based on their content.
Make sure you're also familiar with our Tag What You See policy before editing tags: e621:Tag What You See (Explained)
When you're tagging a post, use the following guidelines:
Replace spaces with underscores
video games should be tagged as
video_games. This small concession makes other features much easier to implement.
The following characters are unusable and will automatically be stripped from tags:
%,#\*- Anywhere in the tag
-~- Only if they are the first character
When adding a new artist tag, attempt to use an alias or nickname instead of the artist's real name. If they go by their real name with everything else, then use their real name. When in doubt, ask the artist. :)
If you're not sure whether a tag is right or wrong, make a topic in the forum asking for some opinions. There will hopefully be plenty of obsessive users who will gladly weigh in.
Tag a post with the tags cat and dog. Tags are separated by spaces.
Words within each tag are separated by underscores.
You can apply a prefix to a tag to change its type. Prefixes are removed for display, so
artist:alicewill only show up as alice.
Tag What it does general:food Changes food to a general tag artist:alice Changes alice to an artist tag character:john Changes john to a character tag copyright:disney Changes disney to a copyright tag species:cat Changes cat to a species tag
These special tags are used to alter information about a post, but not change their tags. These tags do not show up in the list of tags next to the post.
