It doesn’t matter that someone doesn’t know you. You have a message to share with the world and a vlog is the perfect way to do it. Sure, you could create a conventional blog and write posts about your life and share your experiences. But people prefer video.
In a survey conducted by HubSpot a while ago, they discovered that 72% of participants preferred to watch video rather than read a blog post to learn how to do something or find out more about a product or a service. YouTube is a giant of a website. There are 1 billion users who consume hours of video every day. There will always be somebody searching YouTube for what you are good at. This provides you with a fantastic opportunity.
