As I have recently entered the world of SEO, I am very much keen on gaining as much knowledge as possible. Through the net, I have come across several articles that mentioned the importance of keywords, how Google spider algorithm works and many more. However, I also want to read more about SEO services, how the actual process takes place, etc. I do not want to miss out on any topic. I want to cover all of them. If you have any SEO book that I can read to learn about different ways of optimization, then can you please suggest me? E-book is also preferable.
