I'm drafting a user research plan for the next year on a higher ed site, and am interested in including a short online survey in addition to a few other, in-person user testing methods. Our site receives a lot of traffic from different groups (prospective students, parents, current students, faculty/staff), but only the last two groups have email to broadcast that this survey exists.
I suppose my question is really simple. Since many of these visitors are anonymous, what would be a good way to communicate to them that we'd love to hear their opinion of the site, without resorting to a pop-up? Just a link marked "survey" and hoping people see it?
