Let me do an example. Suppose your marketing agency is based out of Florida and you have a massive lawn-care client. They have a fleet of like 40 lawnmowers and 75 staff. They are the biggest lawn care company in the state. How would you establish this from a reputable source(s), so that it could be cited in other places, such as Wikipedia, etc? What would you do? Hire a guest blogger(s) to do research on the topic, build a list of the top 10 biggest lawn care companies in Florida, by doing Google searches and making phone calls? Then have them publish it on their blog? Tweet someone at a large publication that article idea? Would be pretty badass if someone with experience would weigh in. It's a pretty far shot, cuz this isn't your typical BHW question.
