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 hydraulic and pneumatic components in Pennsylvania”
2“Who supplies custom welded hydraulic cylinders with integrated sensors in Pennsylvania”
3“I need a Pennsylvania hydraulic and pneumatic components partner for outfitting a new piece of mobile construction equipment, who should I talk to”
4“Top hydraulic and pneumatic components suppliers in Pennsylvania for OEM machinery buyers”
5“Which Pennsylvania hydraulic and pneumatic component specialists can design and assemble complete power and motion control systems”
6“List 20 hydraulic and pneumatic components 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.
