Very good book for very beginners who want to read a book quickly and the full definition of SEO. Aside from that, you will not learn much, Marie Prat does not go far enough in the background and explanations are often too succinct and reductive, so that the subject does not really allow. Some code, no tips, just a book that lists the basic points, but at this price, there are much better with the book of Matthew Chartier or Olivier Andrieu.
