You can't scale your business. That's it. That's the problem.
Not your ad account. Not your ROAS. Your business.
When you run ads on Google or Meta with automated bidding — which you should be doing (don't try to outsmart the algorithm) — you're handing the wheel to a machine that's very good at finding buyers. The problem is what you're actually telling it without realizing it.
You're creating a performance mirage for yourself and much, much worse, the algorithm to be trained on.
