Ask four questions about any metric
Record the metric name, its provider, the reporting year and the subject category. A journal may be placed in more than one category and its position may vary. Do not combine a quartile from one system with an impact measure from another as though they were one credential.
Keep indexing separate from ranking
A database listing establishes coverage under that database’s rules. A ranking or citation metric describes a different property. Web of Science collections, Journal Citation Reports information and Scopus source information should each be checked in their own official records.
Compare fit before prestige
Read the journal’s aims and recent articles. Ask whether the contribution, design and article type fit the readership. A paper can be unsuitable for a highly ranked journal even when the research is sound. A metric also cannot tell you how a particular editor will assess your manuscript.
Use a reproducible comparison note
For each candidate, write a short entry such as: “Metric and category verified from the named source on the recorded date; scope fit supported by these recent articles.” Add fees and submission requirements separately. Recheck the information close to submission and avoid undated “high impact” claims.
