Technically, an academic advisor is similar to a guidance counselor, but there is a major difference between the two.
Guidance counselors typically work in high schools. For the majority of a student's high school life they are minors which means that the guidance counselor is responsible for setting up the meetings that occur in their office. They advise students on how to choose the right courses that will help them to get into the right colleges and universities. If a student is having difficulties with school due to personal issues, the guidance counselor is there to provide the best solution.
On the other hand, academic advisors are not responsible for the student. They may advise the student on what they should major in depending on what they want to do with their life. However, it is up to the student to set up a meeting with the academic advisor. They may also advise students on how to build a resume, what classes would benefit their goals and if there are questions they cannot answer, they would usually refer the student to another colleague that works on campus.
