Hi, an experiment. My book, Understanding SEO 50% off for hacker news.<p>About the book: <a href="https://www.fullstackoptimization.com/b/understanding-seo" rel="nofollow">https://www.fullstackoptimization.com/b/understanding-seo</a><p>It's an experiment, it might get flagged. No one might read it. Maybe it gets ignored, maybe some people enjoy the book (and get rid of SEO agencies). I will see.
