An excellent introduction to the methods of link building, a key skills for search engine optimization. I appreciate the tactical focus of the book looking at ways to identify high quality link opportunities and the stories from his past work. The guest chapters are excellent with coverage of specific topics like link building for ecommerce. The only challenge with the ebook? It was last updated in 2015, so some of the tools and specific details are less relevant now. That said, this is an excellent resource for SEO and I would recommend it. I've already used some of the techniques to build links for my own website.
