I’m no admit pro, but I’d caution about worrying about fiddling in the margins, as well as putting the cart before the horse.
The process, it seems to me, is pretty straightforward:
There are tons of schools out there.
A student, if they are doing due diligence, should show demonstrated interest in the school - how else do they learn about fit?
As a practical matter, a student should be advised to leave a “trail” whenever they do something that demonstrates interest if they can. There are lots of ways to do this -
If they go to the website, drop admissions an email with a legit question or sign up for some event. Usually you can sign up for communication.
If they visit FB or other social media, hit the “like” button on something. Probably does little, but can’t hurt.
If they go to campus but don’t have time for an official tour, stop by admission and say a quick “hello” and follow up with an email.
If the school does alumni interviews, make sure to get one (btw, this is a place many schools gauge genuine interest, esp. in their further-flung admit areas.)
If the school participates in a local college fair, try to drop by, go by the table and say “hi” to regional adcom. Follow up with an short email.
There are so many easy ways now, no reason not to use them.
Then, just as, if not much more importantly, the student should be very mindful of indicating interest in the appliction. This seems obvious, but I’ve spoken to more than one adcom who has seen applications that make it clear the school is not top choice for the student either subtly or nearly explicitely (and, as an alumni interviewer, I’ve had kids tell me unprompted, the school I’m interviewing for is not first choice, even though I never ask.) I think it helps to explain the application “yield game” to a kid so they don’t think they are being dishonest. Many kids get hung up on the “1st choice” issue. I tell kids I talk to: Even if XX is not, technically, your first choice, would you be thrilled to be accepted and attend (cause you may not get into your 1st choice.) If the answer is “yes” then I encourage them to make sure that excitement - and the reasons for it - get into the application.
Like @TiggerDad saw with his kid, it is very possible to express strong demonstrated interest (or inadvertently expess strong lack of demonstrated interest) through your essay/application. (The admissions talk at Columbia a few years ago mentioned a student who had included in his Columbia application that he had “always dreamed of going to school in New Haven…”)
I would doubt schools want kids and parents to spend lots of money crisscrossing the country just to show “interest” but schools are pretty saavy at distilling genuine interest/likelyhood of attending from the application process. They have seen it all by now.
And, parents and kids should understand, schools are in a statistical catch-22, in a way, if they play the “accepted student stats” game while trying to yield protect. Lehigh or Villanova might see an 800/800/4 UW applicant, know that they are likely to attend a more competitive school, but if they accept them, their “admitted students” stats number rises. If they reject, to yield protect, they lose that stat bump. So sure, Villanova could engineer a 99% yield by accepting only students for whom 'Nova is a strong reach, but then their admitted student stats drop.
So the clever adcoms try to divine “likely to attend” from the 25-75 students and that is where students should be most concerned about demonstrated interest: in the schools that are a “slight reach” or “reach.”
But I don’t think many schools would want you to drop money you don’t have and take time your kid can’t afford, just to travel cross country and say “hi” in the hopes it tilts an application. There are many more cost-effective ways to do the same thing.
And those visit/admit stats should have ED/REA applications teased out. I’d bet there’s lots of overlap and ED is the hands-down best way (of course) to demonstrate interest and for schools to yield protect.
