Although it’s a truism and/or cliché to say that the first rule of SEO is to write good content, it’s probably also been said somewhere, at least once – I haven’t *searched* for it so I don’t know – that thinking about SEO while writing your good content makes it even better. By which I mean that if you’re thinking consciously about the core meaning of the whole piece while writing every sentence, you end up staying more on topic and writing more useful content. Maybe people who actually know about writing already do this? I wouldn’t know!
