Source Normalized Impact per Paper measures contextual citation impact by weighting citations based on the total number of citations in a subject field. As a field-normalized metric SNIP offers researchers, authors, and librarians the ability to benchmark and compare journals from different subject areas. This is especially helpful to researchers publishing in multidisciplinary fields.

SCImago Journal Rank is a prestige metric based on the idea that 'all citations are not created equal'. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation. It is a size-independent indicator and it ranks journals by their 'average prestige per article' and can be used for journal comparisons in the scientific evaluation process.
