The fourth step is to select the media channels that you will use to deliver your key messages to your target audiences. There are many types of media channels, such as owned, earned, paid, and shared media. Owned media are the channels that you control, such as your website, blog, newsletter, or social media accounts. Earned media are the channels that you gain through third-party endorsement, such as media coverage, reviews, or testimonials. Paid media are the channels that you pay for, such as advertising, sponsorship, or influencer marketing. Shared media are the channels that you co-create or leverage with others, such as partnerships, collaborations, or user-generated content. Choose the media channels that best suit your objectives, target audiences, key messages, and budget, and mix them in a balanced and integrated way.
