<p>Alumni interviewer here. From what I’ve seen, Yale does NOT track individuals showing interest the same way some other colleges do. They understand that most applicants cannot afford to visit the campus so do not worry that a failure to visit will be held against you.</p>
<p>The best way to show interest is to clearly articulate “why Yale” during your interview, if you have one. A surprising number of interviewees tell me they are interested in Yale because it’s prestigious or give vague reason like superior academics. I note on my interview report when an interviewee has obviously done his or her research on Yale. I also note when a candidate has not done his or her research. While I don’t expect a high schooler to have the Yale website memorized, applicants who have never heard of the residential college system, for instance, don’t impart a well-reasoned desire to attend Yale.</p>
