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