Spillover Commerce Case Study
Here is how we took a product from $31,000 in sales to $195,000 in sales, while growing profits by $43,031.59, without wasteful ad spend, or cutting prices.
Here are the numbers:
Here is the full breakdown of the profit and loss for this product, for these time periods:

Ok, so what’s this strategy that 6x’d a product?
Spillover Commerce is pretty simple. Take an existing, profitable Amazon Business, and install a profitable Shopify channel on it, and watch sales multiply.
Sounds simple right? Well, you can read our whole article here. Or if you want to talk to us about how we can implement this for you, click here.
So what did we do? I’m going to lay out the playbook below.
Brand Evaluation
We went through our process to check that they had the right fit for this playbook to work:
Amazon Product Market Fit – Check. They had this before we started
Meta-Market Fit – aka, do they have competitors successfully selling on Meta + Shopify? Yes, they did.
We typically check for Meta-Market Fit by investigating competitors on the Facebook Ads Library, like we are in this screenshot, investigating Gruns.
Platform Specific Offers – Did they have the ability and deire to offer different products on different platforms? Yes, they did. I think anyone would if they saw how profitable this can be.
So they passed Phase 1 with flying colors.

Creatives
They had SOME but not many creative assets. They had product photos, and some videos, but not a lot.
This is common with Amazon brands.
This section really just came down to them being willing to get new creative assets. We helped them establish a creative pipeline.
They made some deals with influencers.
Overall, they got to a minimum viable product.
Technical setup
They had everything they needed on Amazon, but they were really lacking on the Shopify side.
They didn’t really have any landing pages for their products.
We fixed this by just working with them to build something new.
We were still waiting for creatives anyways, so this was time well spent.
Meta Ads Phase 1
If you saw the results from Phase 1 of this project only, you’d think this was for sure a failed project, but that’s exactly why it works.
Check out this screenshot from October 2025, where we were deep in Phase 1.
We needed to go in and test out all kinds of angles before you can get something profitable.
This client tried 20+ creatives before we found one that worked well.
How did we get out of Phase 1?
We had 1 niche angle hit, which then helped us understand that a large portion of the demographic buying these products had grandchildren.
This led to us testing a bunch of new angles, which was the key “unlock” for this brand.
Phase 1 is messy. It’s the hardest part of this entire process, because it’s not systematic.
Luckily, we had our blueprint as well as some well established KPIs that we hit. That’s how we got out of Phase 1 quickly.

Phase 2 – Meta Growth and testing
This is where this account is right now. We are not quite “scaling” yet, because we still need more creative assets.
Here’s a screenshot from November 1 – 19, before BFCM Sales, and we had firmly entered Phase 2:
At this point, we are well into profitability.
We decided this phase started as soon as Meta Ads broke even. Right when we started breaking even from Meta Ads, we saw the first impacts of the Amazon Spillover Effect.
Amazon Ads got cheaper. Ranking spiked. TACOS dropped dramatically from 54% to 26%.
Here’s a screenshot from November 1-19, 2025, the day before BFCM Sales started on Amazon, where we were seeing the Amazon Spillover effect in full force:
This is the exciting part, and we were lucky enough to get here BEFORE Black Friday.
This matters a lot because we could comfortably spend aggressively going into Black Friday and Cyber Monday. If we hadn’t hit this in advance (we hit it about 4 weeks before BFCM), we would have had to spend dramatically less than we did, to preserve margins.
This also meant that while our competitors on Amazon were cutting ad spend, because conversion rates were down, we were gaining ground on our rankings.
It felt like we brought a gun to a knife fight.

Where we go from here
There are still at least a few phases left that haven’t been able to start as of today.
One of the next things we want to do is launch Meta Ads for the other top 3 products. This really involves duplicating the things we did in the previous steps.
Another large opportunity focusing on dominating on Amazon, as the product we started with is still not in the top 10 for all its major keywords.
We could have already started on this effort, but we have been limited by inventory, here’s a screenshot from our Sellerboard inventory dashboard.
Finally, the last really large thing we want to do for this client is dominate on Meta. This is a phase where suddenly it feels like “you’re everywhere” to your customers and prospective customers.
Dominating on Meta is also the most profitable phase, and so we are looking forward to tackling this next!
I’m just happy this client is no longer solely dependent on Amazon’s gravy train.
Now, even if their account gets shut down, they have a durable brand that can dominate on many different platforms.
