There is no business that would not be able to use a video platform with videos about itself, its services / products etc. Tutorials are especially popular.
Videos on Youtube cannot only get a lot of attention, but create an interest in your company. If set up correctly the channel can direct visitors to your website and ultimately lead to conversions!
You can log in to your Youtube profile with your Google Login, i.e. gmail. Uploading a video is easy. You can edit it beforehand with a tool such as Windows Live Movie Maker on your computer or upload it in a raw file and edit it online with one of these video editing tools. Youtube also offers a free online editing tool: www.youtube.com/editor and you could add captions and effects.
