Yes it can. It is called "tracking interest." Every college does not do this. A college will be honest and let you know if they do this, but only if you ask. This does NOT mean call and email the admissions counselors on a daily or weekly basis! It means call or email when you have questions or to check on your application status. If a representative visits your school, make sure you go talk to them. Go to visit the school, go to events they are hosting such as open houses or local information sessions (usually held at a hotel or convention center). They keep track of all of these things and you will be on their radar.
