I've read it and it's a good book. However, I'd like to take the opportunity to point out to the author that there's an English error on the landing page linked above. It should be "Info" not "Infos" since it's not a countable noun.

Thx. The VP Growth of Angellist once called it "SEO for hackers."

I by now sold a few thousand copies as Ebook and print. Mostly in the German spaeking markets. 5 Stars based on 22 reviews an the german Amazon.

Currently mostly doing other ventures so very very happy to give it away and make SEO agencies (and myself) redundant for good.
