The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best machinery repair and rebuilding companies in Illinois”
2“Who supplies emergency industrial gearbox repair services in Illinois”
3“I need a Illinois machinery repair and rebuilding partner for a critical production line outage, who should I talk to”
4“Top machinery repair and rebuilding suppliers in Illinois for plant maintenance buyers”
5“Which Illinois machinery repair and rebuilding providers can handle on-site CNC machine diagnostics and overhaul”
6“List 20 machinery repair and rebuilding companies in Illinois with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
