Video is an engaging addition to a website. Not only is is a great way to show off your products or services, Google loves video and rewards sites with video. Video can also be distributed to various video sites, and posted to YouTube and Facebook pages.
It has become increasingly easier to get your video on the web. With Flip video cameras and video-capable phones, it is hard not to own one. If you have a smartphone, you can shoot, edit and post your video to the web without a computer.
WARNING: While video is a great addition it is not a substitute for text on the page. In other words, Google can't dig into your video and know what it is about. You need to have captions and additional text that discuss the content of your video.
