Make your Video
There are 3 ways to make your videos
1. Use a camcorder, then transfer the video to your computer, where you can then edit it, with the editing software that came with the camcorder.
2. Most webcams come with software that allow you to record video and audio directly to your computer, then you can upload it to YouTube.
3. YouTube has an application built in called quick capture which can directly record your video to YouTube from your webcam.
I would prefer to use the camcorder method, and then import it and edit it into my computer, so that I can watermark the video before, after, and through the video with my website url.
Method 1 and 2 will require you to upload your marketing Video to YouTube manually.
What on earth do I make my videos about?
Anything you want! It could be a How-To video on search engine optimization, affiliate marketing, even products that you offer for sale.
But wait. It also could have a short movie, a comedy skit, a parody, even whats rolling around in your mind.
If people enjoy it, they will probably check out your website. That is why I recommend that you watermark your video with your website url.
So now your drawing traffic that would have never visited your site.
Drive more traffic
YouTube offers video community called groups, when you upload your videos you can sort them into the relevant groups. where you can have discussions within that group. I suggest you join the groups that fit the theme of your video.
YouTube also offers whats called video responses where you respond to someone elses video its a good way to get your video noticed, but once again, I suggest you stay relevant to the topic of the original video.
As a final note, embedded videos from YouTube that are played, are listed as a referring url, and will be displayed on the YouTube video page. This is an added bonus, as it will allow search engines to crawl your site faster, and give you a little Google page rank bonus.
