Earned Media is a marketing source that you can’t necessarily purchase, but you must work very hard to earn. Public Relations is a prime example of Earned Media. While you can’t pay a respectable journalist to write about your product in their publication, you can work hard at crafting an effective press release and making the right contacts to ensure that your product gets coverage. The same principles apply to other types of Earned Media, such as SEO (Search Engine Optimization). While you can certainly buy services that will help you with your SEO initiatives, you can’t simply buy the number one organic ranking from Google. A lot of work must go in to succeed in Earned Media. Additional information is available here.
