Good Day,
Can someone recommend some good advance level books on SEO?
I am looking for book with in depth knowledge of SEO. I have seen many on amazon but as i am living in Australia its good to have a opinion before drag the book all the way here paid a lot and wait longer and finally revealed its not worth it.
Basically i am not looking for tips or tricks etc, I am interested in detailed knowledge sharing and different strategies.
Thanks in advance.
