Don't waste money on courses. The real education is in Google's own documentation, the platform forums, and just running tests yourself. Free resources like Ahmeego's blog, testing tools, and breakdowns are far more useful than any masterclass.
No course is going to teach you the visual hierarchy that actually moves ROAS - that comes from building your own library of hooks and creative frameworks through trial and error. The only masterclass that matters is the time you put into the craft. Practise the formats, test the psychology, and let the metrics guide you. Anything else is just someone else's outdated playbook.
