Tried some free SEO audits, and they website is getting scores in the 80s. But what is really making me optimistic is me testing it for myself. Googling Laravel (in our language) for example, the website is the first result, above Laravel's official website and Wikipedia. And in the first page for "Godot", "How to learn programming", "Cloud Computing", "Vue JS", and more.
I will start my new business as a subdomain, leaving (and adding) to the existing articles.
