How big a role does your digital footprint play when it comes to selection into the most competitive colleges (Ivies)? Answered
Do you need to have an extensive digital footprint (YouTube channels, blogs, websites, etc..) in order to be selected into the best colleges?
No. They can absolutely be an important part of an applicant's activities list depending on their focus and goals, but you don't *need* them by any means.
As in demonstrated interest? I would be happy to answer, I just want to be sure to answer your question correctly :)
