SCImago Journal Rank (SJR):
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
Source Normalized Impact

SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
