Here’s a look at some of the differences between marketing vs. public relations: Objective – PR specialists cultivate a positive public image for their clients, whereas marketing specialists strive to generate more sales for the company, formats – marketing specialists may use a variety of marketing campaign platforms and formats to achieve their goals, such as social media posts, blog posts, website copy, sales emails and paid ads. In contrast, PR experts have a somewhat limited arsenal, primarily relying on media interviews, press releases and speeches, and results – marketing specialists primarily measure their results in terms of sales generated for the company. PR specialists evaluate the amount of positive press generated, awards won and the general public opinion of the client.
