recruiting - How to improve graduate student recruitment at a small, good, but non-elite department?

I am a mathematics professor in a small, good but non-elite department in the US. Several of my colleagues and I would like to work to improve our recruitment of strong prospective Ph.D. students.

We do not really know how to go about this most effectively. Obviously it is difficult, but -- what are some good ways to do this, in addition to

1. maintaining a useful and informative departmental webpage,


2. serving our present Ph.D. students as well as we can, making sure they are happy, and (hopefully!) helping them to land good jobs,


3. maintaining our own research programs, and



4. continuing to network and maintain professional connections with colleagues at other universities?

Edit: I see this question is related, although in my case recruiting is handled on a departmental rather than individual basis.
