What is brand positioning?
It's the answer to one question: why should this customer choose you instead of the alternative? A strong position is specific, believable, and something a competitor can't easily claim.
Most businesses skip this step. They describe what they do ("quality service, competitive prices, family owned") and end up sounding exactly like the company down the street. Customers can't tell them apart, so they choose on price.
Good positioning ends that. Good messaging makes it stick: a few clear words, repeated everywhere, until people say them back to you.
