The first criteria could be the area of major that college is known to be strong at, because ultimately you come to university to pursue a certain spectrum of knowledge that you would later apply to your job. Thus if your college doesn't have a strong program in your field of interest, it would be hard to find a job, which are usually interested in students who come from a college who is known to be strong in that field
The second criteria is the location because once you narrowed down to the last few college that fits your education need, you need to check its location to determine the safety and whether you feel comfortable with the surrounding. Why location is so importance, it is because location is something that you cannot change and that you must live with while other criteria are bit more flexible for you to change and adapt to.
Hope that helps!
