I agree with you about the majority of "SEO content marketing", but a small minority of it is done by companies who genuinely care about doing good content, that doesn't only act as lazy SEO benefit but also as good marketing for people who read it.

It's a lot harder / more expensive to produce, as it needs (at least before AI, and I guess still to some extent even using AI for now) to be written by someone on the team who genuinely understands the company's technology/product/whatever well enough to educate other people about it in an interesting way, rather than it being written by low wage SEO writers who just need a list of keywords to include in the drivel that is the sort of content you're talking about. So it makes sense that most companies go with the cheap option, but it's always nice to come across ones who produce actual interesting articles.

(It's what I've always opted for when I've overseen marketing budgets, and I think the ROI is usually worth it since balancing the extra cost is the fact that the benefits go from just SEO, to SEO + word of mouth of people sharing the interesting article they read, and the awareness of the brand that comes with it. So I recommend anyone who normally chooses lazy, low quality content for SEO to consider the upgrade!)
