The key word in SEO is "Optimization". What is the author optimizing for? He's a developer who's maintained a dev blog for many years. Chances are when he started blogging, he wasn't thinking about selling e-books and courses or about competing for business with other developers who pursued a similar path.

That is the polar opposite of what "Optimization" means for businesses. Usually they're in a competitive product category, and there are lots of competitors who're not only churning out blog posts to boost their organic search hits, but also buying your product's keywords and advertising against you.

Online discoverability is a zero-sum game, so the tactics tends to be fairly scorched-earth compared to what they would for a personal website.

If you Googled "flavio copes", you wouldn't see an ad at the top of the search page that reads "Flavio is a bad developer. Click here if you want a real 10X developer on your project".
