Assuming that you ask for additional criteria for quality metrics of a journal, I would add at least the following from an author's viewpoint:

• ease of the submission preparation and process (for example, it is unnecessary for the initial submission to stick to the final formatting guidelines but almost all journals require this)
• quality of the reviewers' feedback
• speed to publication
• Open access policy

Thanks for your answer Michael. Your points are really interesting. There should be some matrix to measure the ease of submission and to ensure quality of reviews too.

I can think of one more criteria for quality metrics of a journal which is Journal's special scope. Some journals have a wide range of scope and publish papers in many fields while some other journals have a narrow scope and publish in specific fields, i believed the second type have much better qualities. Beside this one, i think your metrics along side the ones suggested by Rajesh cover the question.

Thanks Reza for your answer. The scope of the journal is one another matrix for quality evaluation. Hope this could be useful for #Scopus to improve their present matrices..

Some other important indicators

• acceptance rate
• average time from submission to acceptance and to publication

Thanks Artur for the answer. I think Springer journals are showing the speed as one of the matrix. Acceptance rate is an important criteria and often not considered in any of the matrices.

Great initiative. it's really important to understand the journal performance parameters before submitting a paper. Few parameters in detail can be checked on the given link:
