Video blogging or vlogging, has gone mainstream, or at least is a huge phenomenon now that bandwidth has increased, compression has improved and camera equipment has gotten so much cheaper. Even a built-in webcam in a laptop is adequate for many purposes to produce a reasonable quality result. Even HD and wide aspect is within reach of most people.
Not that it is easy to come up with good content instead of text posts, but it can be quicker for some people who don't shy away from being in front of a camera and talk well.
But how do you do SEO and link with video? Is there still a bit to figure out and rework for a marketing campaign?
