What Is CiteScore? Scopus Metric vs Impact Factor
Discover how CiteScore works, how it differs from the Impact Factor, and why Scopus's free metric matters for journal evaluation.
SectionDefinition
CiteScore was launched by Elsevier in 2016 as a transparent, free alternative to the subscription-based Journal Impact Factor. Every journal indexed in
SectionThe CiteScore formula
In plain terms: take four years of publications, count all the citations they received across those four years, and divide by how many documents there were. Different windows: 4 years (CiteScore) vs 2 years (Impact Factor)
SectionImpact Factor
2023 2024 ↑ Both count citations made in 2025 to the documents in their window. The wider window is the main reason a journal’s CiteScore and Impact Factor are rarely equal.
SectionKey differences
This is the comparison most researchers actually need. The two metrics answer a similar question with different rules:
SectionReading the rank
A raw CiteScore is hard to interpret across fields, so Scopus also reports a CiteScore Percentile and a quartile ( Q1 – Q4 ) within each subject category. A percentile of 95 means the journal out-ranks 95% of titles in its category. For cross-field comparison, the percentile is far more meaningful than the raw score — a 3.0 CiteScore can be elite in one discipline and middling in another.
Key Takeaways
- CiteScore is a free 4-year metric from Scopus.
- It divides citations by documents over a rolling window.
- CiteScore and Impact Factor rarely match.
- Use CiteScore for broad coverage; IF for recognition.

Practical GuideHow to Find a Journal’s CiteScore
Finding CiteScore is one of the easiest ways to evaluate a journal because it is freely accessible. Follow these steps:
- Go to Scopus Sources (no login required for basic search).
- Enter the journal name or ISSN in the search box.
- Click on the journal title in the results.
- View the CiteScore prominently displayed on the journal profile.
- Check the CiteScore Tracker for the current year’s provisional score.
Unlike the Impact Factor, which requires a JCR subscription, CiteScore is openly available, making it a popular choice for researchers without institutional access to Clarivate products.
Common MistakesErrors When Using CiteScore
- Confusing CiteScore with Impact Factor: They use different windows (4 vs 2 years) and databases (Scopus vs Web of Science). They are not directly comparable.
- Ignoring document type differences: CiteScore counts all document types in the denominator, while JCR IF counts only citable items (articles and reviews). This can make CiteScore appear lower.
- Comparing across fields: CiteScore, like IF, varies by field. A CiteScore of 3.0 is excellent in mathematics but modest in biomedicine.
- Using outdated scores: CiteScore is updated annually in June. Always check you are using the most recent release.
FAQFrequently Asked Questions
Is CiteScore better than Impact Factor?
Neither is universally “better.” CiteScore is more transparent, free, and covers more journals. Impact Factor has a longer track record and is more widely recognized in academia. Use both when possible.
Why is my journal’s CiteScore lower than its IF?
CiteScore includes all document types (editorials, letters, notes) in the denominator, while IF counts only citable items. This typically makes CiteScore lower than IF for the same journal.
How often is CiteScore updated?
CiteScore is released annually in June, covering data from the previous calendar year. The CiteScore Tracker provides monthly updates for the current year.
Does CiteScore include self-citations?
Yes, CiteScore includes self-citations. However, Scopus also provides a separate metric called “CiteScore without self-citations” to show the score with self-citations excluded.
