One of the few courses worth the money. It actually takes you through the technical steps such as how to connect your website to GSC, build content, etc.
-the things that matter more than just philosophy.
@thetafferboy has a course/classes of some sort out there in the world (hard to find).
I've seen them and the curriculum listed over the past couple of years on LinkedIn - and from what I've seen, they're thorough.
If you ask him nicely, he has let some people test it.
The BrightonSEO Technical On-Page SEO Course (On-Demand)
I paid for this one. It's almost entirely high-level concepts that won't leave you better at doing your tasks. Instead, you'll have a general understanding of how websites should be organized.
SEMrush Keyword Research and Technical Audit Course.
These are free and they're about concepts. You're not going to learn how to do the work. And while the certificate sounds nice, it's not viewed highly via people hiring for SEO professionals.
Not a course, but this was a great "over-the-shoulder" view of someone doing keyword research/planning. I have repeatedly used this to help train other SEOs.
