Incremental growth can look straightforward on the surface. But the real question is what happens to the economics underneath.
In digital commerce, a strong ROAS can make a channel look highly effective. But ROAS does not necessarily tell us whether the business actually grew. The harder question is:
Did this media dollar create a sale that would not have happened otherwise?
That is the difference between attributed sales and incremental business impact.
Why ROAS Does Not Always Equal Incremental Growth
The consumer journey is increasingly fragmented. The same consumer might shop on Shopee on Tuesday and at a local supermarket on Saturday. For FMCG teams, that creates a measurement problem.

When a sale happens through social commerce, it is tempting to treat that transaction as evidence of incremental growth. But the transaction may have simply moved from one channel to another — or happened earlier than it otherwise would have.
The sale is real. The attribution is real. But the growth may not be incremental.
And that distinction matters when we decide where to put the next media dollar.
Growth Is Not the Same as More Transactions
Digital commerce makes this distinction particularly important because consumers do not think in channels. They move between platforms, stores and touchpoints. The channel structure belongs to the business, not the customer.
So a channel can grow quickly while incremental growth remains limited. And a campaign can deliver a strong ROAS while profitability tells a different story. The more useful question is not simply:
“Which channel is growing?”
It is:
“What business would not have existed without the investment?”
That question changes the conversation from platform performance to business impact. It also changes how media reallocation should be evaluated.
The goal is not simply to move more transactions into a growing channel. The goal is to understand whether that channel is creating additional business — and whether the economics justify the investment.
Three Ways Growth Can Look the Same in a Dashboard
1. Demand Creation
A shopper buys through social commerce while maintaining their normal offline purchasing volume. The transaction is genuinely incremental.
There is additional revenue that would not have existed without the new demand.
2. Channel Shift
A shopper buys through social commerce instead of making their usual offline purchase. The ecommerce channel grows. The transaction is real. But total volume stays the same.
The business has shifted where the sale happened, rather than creating a new sale.
3. Demand Pull-Forward
A shopper buys earlier than they otherwise would have. This week’s ROAS looks exceptional. But the next replenishment may disappear because the consumer has already purchased.
Again, the transaction is real. But the timing of demand has changed.
These three scenarios can look surprisingly similar when the dashboard only tells us where the transaction happened. The business impact is very different.
The Question Behind the Metric
This is why incremental growth matters.
If we only look at attributed sales, we can easily reward a channel for capturing demand that already existed. We may then move more trade investment into that channel because the ROAS looks attractive — even when the underlying business economics do not improve.
The more useful question is not:
“Where did the sale happen?”
It is:
“Would the sale have happened without the media?”
I explored this tension in practice in When High ROAS Doesn’t Mean More Growth. That question changes how we think about media effectiveness. It also changes how we think about profitability.
A channel can show strong growth.
A campaign can show strong ROAS.
And yet the business may not be creating enough incremental value to justify the investment.
Look Beyond Channel Metrics
Digital commerce gives businesses more ways to reach consumers and capture transactions. But more ways to capture a sale do not automatically mean more business. The challenge is understanding what kind of growth we are actually creating:
Is it new demand?
Is it channel shift?
Is it simply demand pulled forward?
And ultimately, does the additional business justify the economics of getting there?
Sometimes the most important number is not the ROAS on the dashboard.
It is the business that would not have existed without the media.
