In B2B—as in all business—trust is everything.

And one of the main sources of trust is a sense of someone’s authority: the sense that this person or company has earned the right to talk about this subject; that they’re judgement is based on real experience and expertise; that other people recognize this status.

I can think of three main ways to give someone a sense of your authority.

You can claim authority – Just state it: “We are experts.” And, ideally, support it with some data or third-party endorsements. (Doesn’t mean you’ll be believed).

You can demonstrate authority – By walking the talk: sharing your expertise in content.

You can signal authority – Using things like brand, imagery, design and the semiotics playbook used by governments (presidential seals) and police forces (badges and, like, guns and stuff) and nightclub bouncers (black T-shirts and bloated biceps).
