For the past few months, whenever a reader asks a question, instead of sending an email reply, I record the answer as a public video on my YouTube channel[50] and send them a link. This requires slightly more time, but doubles as a permanent piece of content to help build my fledgling audience. As we’ve already discussed, the “trick” of sustainable marketing is to find ways to integrate and overlap it with whatever you’re already doing, and answering reader questions is a perfect fit for that.
