Performance is hitting a wall – scaling spend just tanks our MER. Is it the creative or the structure?
Posted by on March 28, 2026 at 3:34 pmWe’ve been running a fairly successful shop in the electronics/home office niche for about 18 months. Currently spending around $15k–$20k/month across Meta and Google, but every time we try to push the budget past that, our efficiency just falls off a cliff.
Our ROAS looks "okay" in the dashboard, but our actual Marketing Efficiency Ratio (MER) is starting to suffer. I’ve tried the usual Advantage+ campaigns, broad targeting, manual bidding but we’re just cycling through the same results. I feel like we’re missing a deeper strategic layer, maybe something related to our attribution model or even the post-click experience.
I’ve been looking into some of the frameworks and resources over at iitd com to see if we’re fundamentally miscalculating our scale potential. I’m seriously considering bringing in an ecommerce consultant who actually understands the technical side of paid media, not just someone who can "set up a campaign".
Has anyone here hired a specialist specifically to break through a spending plateau? I’m curious if I should be looking for a media buyer or someone more high-level who looks at the whole ecosystem (LTV, retention, landing page flows).
Any advice on how to transition from "managing ads" to "scaling a brand" would be huge.

Instead of spending $20K on two ad platforms. Look at spending all that on one platform and get better at scaling because you have enough data in one ad platform. The big reason you can not scale is because you don’t have a high enough ROAS to let you spend more. You don’t have the proper campaign set up nor stable enough results to let you scale more.

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

Fully automated campaigns will only get you so far. To scale profitably you need strict control over CAC, margins and profits, customer segmentation, tight audience management and retargeting windows.
The reason your MER falls off is you’re just pushing more spend to the same “low hanging fruit” audiences, because you don’t have a proper acquisition pipeline in place to reach and convert new buyers beyond the easy wins.

Hard to say with the info given…
What’s the price point? Sales cycle? Maybe you’re measuring too early…
Are you using first click capi imports or last click (default)?
Is your media buying prioritized towards ROASor filling the funnel?

Thats because your not taking into account margins and LTV when you plan what products your supporting in-feed.
This is why ROAS is becoming more like CTR.

Your creative is exhausting faster than your structure can compensate at that spend level new angles matter more than account restructuring right now

Felt this hard. Hit the exact same MER wall around $20k/mo. The comments are right about audience saturation, but for me, the real bottleneck to reaching new buyers was creative velocity.
When you push Advantage+ harder, your winning creatives fatigue instantly. I stopped trying to hack the campaign structure and started feeding my raw product photos into a platform that auto-generates full commercial lifestyle scenes. The killer feature is I can upload a competitor’s winning ad, and it reverse-engineers the lighting and layout into a reusable template for my own products. It also auto-formats everything for Meta and Google Demand Gen (4:5, 9:16).
It occasionally hallucinates complex text overlays so I still have to clean some up, but testing 40 new visual angles a week without a photoshoot budget is what finally brought my CAC down and unlocked scale.
