All of these questions can help determine what type of video you should make and where you should post it. For example, if your target audience is not familiar with your company, you probably want to make a video that focuses on brand awareness before producing an in-depth, product video. You'll also want to host your video on a site that already has a large reach, like YouTube.
Sound: Yes, often viewers are watching video ads on silent, mainly on Facebook. But when they’re not, what a world of difference a good track adds to your video. A great tip from the Promo sound editor was, to conder sound an enhancement to every video. A recent study found that when the music in an advertisement fits the message and imagery of the commercial, consumers were significantly more emotionally affected and remembered it longer. Now, this means you can choose music that plays to the tone of the video, or for a bit of humor, take your sound in the opposite direction. This contrast can be video magic and certainly something to make sure you’re remembered.
Ideally, you’ll use all three distribution methods. You know your audience and hopefully you know how they’ll respond to your video. Focus on the distribution method that’ll give you the biggest return. If you’re in the film industry, focusing more on paid distribution might be your best bet. If you’re in the field of cancer research, earned media might be the way to go. Are you an entrepreneur that just launched your own startup? Spread word via your owned channels. It all really depends, so do a little research and see what fits your situation best.
