Request for Advanced B2B Content Writing Resources and Frameworks for AI Training

Hey Folks 👋 I'm working on training an AI agent to write killer first drafts of B2B blog posts, and I need your help sourcing material. Specifically looking for: • PDFs, playbooks, or style guides on B2B content writing (HubSpot, Moz, Semrush-level depth) • Frameworks that balance SEO optimization with genuine human readability • Annotated examples or rubrics that content teams use to score draft quality I've covered the basics already. Looking for something more advanced and structured — ideally something I can use as a grounding doc or training reference for the agent. If you've built something like this internally, stumbled across a great resource, or know someone who has — drop it here!
