Hm.
The course is given by one person, but the videos are by another. This is a very very basic tutorial that most will already know if you've been experimenting. The videos are okay at explaining the extreme basic and would fit better with a 'Beginners Course' title, but they should have had some sort of sound to them as well. The very last video I didn't have any audio on either; I receive audio for everything else aside from this course so I'm guessing the audio was never attached properly. Good course for a brand new user to SEO.
