How can I start learning digital marketing online? There are so many courses, so many different topics (SEO, social media, Google ads, etc.), and I get lost. How can I get organized?

I was in the same boat about 16 to 17 years ago. It took a while but I began to learn with sources that were trustworthy. As of today, I would trust Moz’s Whiteboard Fridays, videos, and articles, SEMRush articles, Ahrefs, Search Engine Journal, Search Engine Land, Aaron Wall, etc.
