Goodfic

Goodfic, as can be determined from its name, is good fanfiction.

Many people disagree on what is a goodfic and what is not, but generally, goodfics have the following characteristics.

Goodfic Characteristics

 * Excellent Characterization.
 * Follows Canon
 * Or Extrapolates on Known Canon while remaining believable for that canon
 * Correct Spelling and Grammar.
 * Canon Characters remain in character or follow a believable path from how they are characterized in the canon to how they end up in the fanfic.
 * Believeable original characters that do not break the story.

Recognizing Goodfic
Recognizing goodfic is a problem in some fandoms due to Big Name Fans, shipping wars, and established fanon.

Some factions in a fandom might recognize a fanfic as being a goodfic that other factions might consider a badfic due to themes and/or general squickiness.

Goodfic/Badfic Paradox
All goodfics are able to be considered as badfics by fandom factions.

However, no real badfic will ever be considered to be an actual goodfic.
