HubSpot Academy's Inbound Marketing course is free, well-produced, and comes with a certificate that's recognized in many marketing job listings. It explains how content, SEO, social media, and email work together to attract people and turn them into customers — the mental model most modern marketing runs on. Yes, it's made by a company that sells marketing software, and the examples lean that way, but the fundamentals are sound and tool-agnostic. It's the best free overview before you specialize.
