Academic journal rankings can be used to evaluate a journal's quality and importance in a particular academic field. Mathematical formulas are used to assign an impact score to a journal title based on how many times a journal has been cited by other publications.
- No single database that scores all journals, and different citation databases use different scoring metrics.
- Journal ranking scores are one tool in evaluating journal quality. Types of articles, language, journal history, and changes in title and format could also affect citation rates.
- Predatory publishers may use a fake journal ranking score. Impact factor and other journal ranking scores should be verified.
