Just like with podcasts, you don't need to be computer savvy to make videos or post on YouTube. Nor do you need to be a professional director or producer. You don't even need a camcorder—most digital cameras and cell phones can record video. So pick a topic you enjoy and shoot. Upload your video on YouTube and embed the video player on your blog.
Rest assured, YouTube offers basic instructions for how to do all of this on their site.
The possibilities are endless. Your main goal in uploading some video is to connect with people who might be interested in your work... and who might buy your audiobook.
Tip: To be sure your video is easily found, tag it with keywords that describe the content.
