Rankings of mathematical conferences and journals Just to keep it simple: What rankings of mathematical conferences and journals are available in the internet?
(I'm only interested in rankings, not about any discussion about rankings.)
 A: I myself am not very fun of rankings. But when the Library of my University
decided to cut down some of the journal subscriptions
(due to the budget crisis in the Eurozone), I gave my personal viewpoint
by means of creating a unbiased ranking of Mathematical Journals.
Mainly what I wanted to measure was the impact of the Maths published
by each Journal throughout its life  on today's Math. I took the raw data from MathSciNet.
The result can be consulted in the web page of the society journal of
the Spanish Math Society (the "Gaceta de la Real Sociedad Matematica Española"):

and also in my personal web page:
http://personal.us.es/arias/V17N3_439.pdf
The paper, where I explain the procedure devised for creating the ranking my procedure, is in Spanish,
but at the end you can find the ranking, which is easily understood.
My ranking treats on the same footing all journals in applied, pure and statistical math.
A: There is the Report of the IMU/ICIAM Working Group on Journal Ranking (June 2011),
and the IMU  blog on mathematical journals, discussing exactly these questions, and giving lists of such rankings.
A: Here are the rankings of (not just math) journals employed by some countries:


*

*Brazil (in Portuguese)

*Finland

*Norway 
A: You can also check out http://zbmath.org/journals/ for details on the journal content. It doesn't give you a ranking though but you see at a glance, who published in the journal you are interested in or what topics are represented in the articles.
A: The Australian Mathematical Society have produced a ranking:

It is widely used (for instance, by my own institution in the UK).
When choosing where to submit I also make use of the following ranking of journal prices/ value:

Of course it's a different type of ranking, but you might argue that it's a lot less subjective!
