He doesn't show any statistics from his own blog to back his theories up.

I don't know, I don't think these are any valuable SEO lessons imo. The tl;dr of this post is "I find SEO optimization boring so I just write whatever I want and don't think about it".

There is nothing wrong with that statement except that it isn't a SEO lesson. Sure quality over quantity is a good SEO lesson. To provide stuff of value is good for SEO but that goes without saying.

SEO is about optimizing your content and the value you already bring. If you load the whole blog async for example, it won't be very good for SEO no matter how good or helpful the content it.

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".
