Best beginner resources?

Hi all!

I'm new here and getting my feet wet in online marketing.

Can you recommend the best beginner-friendly resources (blogs, YouTube channels, free courses, forums/specific BHW threads) that teach practical tactics and step-by-step workflows? I'm especially interested in SEO basics, link building, affiliate marketing, and simple site build/WordPress setup.

Which were most helpful when you started, and one quick tip for a total beginner would be appreciated. Thanks
