YouTube + practice? That's the one thing most performance marketers won't tell you because they're too busy selling you on fancy attribution models and multi-touch funnels. In B2B SaaS, I've seen more pipeline velocity from someone who actually sat down, watched real campaign breakdowns on YouTube, and just ran experiments than from any agency that charges 15k a month for "strategy."
Everyone wants the secret sauce. There isn't one. The people who actually move numbers are the ones who test ad formats until they break, copy what works from competitors, and don't get paralysed by analysis. YouTube is basically a free, uncensored playbook if you filter out the guru garbage. And practice? That's the part nobody wants to do because it means failing in public with your own budget.
So yeah, YouTube plus actually touching the keyboard beats every certification and conference talk I've ever sat through.
