I'd just point out that things like Backblaze's drive reliability blogs are absolutely content marketing. There's plenty of low-rent clickbait out there but there's also good material that is ultimately being created and paid for for marketing purposes. (And SEO isn't all black hat. For example, if you're writing about some hot topic, you probably want to mention it in the title and not take forever to get to it in the article.)
