I have got Source Normalized Impact per Paper (SNIP), 2 years and 5 years impact factor and SJR journal rank in journal web site. Among them which one would represent the Quality factor of a journal?
Impact factor of an academic journal reflects the yearly average number of citations to recent articles published in that journal.
While on the other hand, Quality Factor of an academic journal is a measure of quality in that journal. It is commonly used as a representation for the significance of a journal within its field.
There is no single, definitive metric for a journal's quality, Ali. That is why there are so many different metrics utilized. Like all metrics, one must interpret each in context. In my discipline, for example, citations seems to continue for several years beyond the 5-year impact factor which suggests to me that reliance on any of the metrics is probably not fully justified in my discipline.
I would also like to mention that electronic access to articles has seriously weakened, in my view, the importance of the journal's reputation. As long as an article is electronically and widely indexed, others can locate it and determine the merits of the findings of the article without concern about the publication medium. The quality issue that is becoming most important is the quality of the manuscript, not the quality of the journal.

But most journal showed only SNIP, JCR impact and SJR ranking in their web site. I did not find any journal Quality factors from its web site. How do we find it? @ Segun Michael Abegunde
