What "impact" do things like citation counts and scholarly profiles have on promotion and tenure?
Those are decisions made by each department or college on campus.
Department chairs should be consulted to learn what is useful in your discipline.
You might also consult colleagues who have recently been awarded tenure/promotion to see how they may have used some of these tools and which they found most helpful. You'll need a selection of tools and those will vary by discipline.
This guide will provide information on tools and techniques for measuring the impact of scholarship in a global research environment.
