the way you scale an ecom brand on google has changed a ton over the last few years.
be very careful taking advice from guys who made their money running basic search, shopping, and pmax
watched a few of their youtube videos recently and all the stuff they're preaching is low leverage. barely moves the needle today.
with how much more important landing pages, creatives, funnels, and proper prospecting are now, most of these guys would get smoked trying to compete today.
