Not quite the same.
People trust marketers LESS than lawyers, bank executives, journalists and real estate agents. Public relations executives have taken over from estate agents as the professionals the public trust least. Fewer than 20% of people say the paid representatives of a company are credible sources of information.
And, when people think marketing, they often think of "all style, no substance". Flakes, fluff, and eye candy. But it doesn’t have to be that way.
Marketing is as much an art as a science. Part intuition, part analysis.
Most marketers are heavily skewed toward communications or straight sales. Great concepts or great numbers. But rarely both.
