What you need are deep insights into your audience. To find them you'll need to run surveys, conduct interviews and sift through data. Start by gathering basic information like demographics, then move onto more detailed considerations of personality and preferences. Be sure to get to the root of what your audience need, what they want, and which problems you can help them with.
You can work with bloggers or influencers to create and promote videos. Rather than dealing with making the videos yourself, or paying someone else and then having to find a way to promote them, why not work with someone who can make and promote your videos? Vloggers with a large and relevant audience will be happy to work with you on a partnership. By integrating your product or service into their current video format, there should be little extra work for them to complete.
