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 suppliers of industrial and process controls in Ohio”
2“Who supplies PLC-based industrial control panels in Ohio”
3“I need a Ohio industrial controls partner for automating a new production line, who should I talk to”
4“Top industrial and process controls suppliers in Ohio for manufacturing engineering buyers”
5“Which Ohio industrial controls integrators can handle safety-rated motion control systems”
6“List 20 industrial and process controls companies in Ohio 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.
