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 boilers in Ohio”
2“Who supplies high-pressure packaged fire-tube industrial boilers in Ohio”
3“I need a Ohio industrial boiler partner for a new food processing plant installation, who should I talk to”
4“Top industrial boiler suppliers in Ohio for facilities and maintenance buyers”
5“Which Ohio industrial boiler companies can handle turnkey installation and commissioning of 100,000 lb per hour steam systems”
6“List 20 industrial boiler 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.
