I have to thank Daragh Walsh for clarifying quite a few things about search engine optimisation on websites and pages. Each of his lectures was relevant, to the point and easy to follow. By the end of each lecture I knew what the benefit of doing it was and I knew what to do to apply the knowledge to my own situation. I didn’t particularly need the lecture on search engine optimisation for business sites but I learned a lot about how Google sets this up and so how it is working or not working for me when I am looking for a local business online. Daragh actually took the time during the course of the lectures to explain how to use the comments and questions sidebar in the Udemy courses. He is the first of the four lecturers to do that even thought they all invite you to use the question section. It is a good idea to have the sidebar but it is a better idea to explain its use and maybe each of the Udemy courses needs the first lecture to be that and one which is not counted towards the course but a generic explanation so that everyone knows what to do and is consistent in their approach. It might also help to suggest ways of using it effectively. This is my fourth free course so I have one more to do. In the four courses I have had different English language accents. This is great for anyone learning English but it is also great to see that Udemy is drawing on human resources from all over the world. In terms of what Daragh said in his SEO for Beginners , it builds authority and one of the most useful pieces of information I gleaned form this course was how to check and build authority on sites/pages. My next course is going to be Web Design for Web Developers: Build Beautiful Websites! by Jonas Schmedtmann and I am looking forward to it.
