Reply To: Performance is hitting a wall – scaling spend just tanks our MER. Is it the creative or the structure?

That usually means the issue isn’t media buying anymore, it’s the handoff after the click. When spend scales, weak attribution, a soft landing page, or poor repeat purchase flow can make platform ROAS look fine while MER gets worse. I’d audit the numbers from ad click to repeat order before changing campaign structure again. Shariq
