From vanity metrics to real profit
Every year, ecommerce brands pour millions into Black Friday and Cyber Monday campaigns chasing screenshots of record-breaking ROAS. The problem? ROAS doesn’t equal profit. If you’re not connecting ad performance to COGS, margins, and inventory, you’re gambling, not scaling.

This is where brands win or lose
Not on top-line revenue, but on sustainable Black Friday profitability.
By using MMM, incrementality testing, and epROAS (effective profit ROAS) before peak season, you stop guessing and start scaling on facts profitability.
epROAS that matters → returns after costs
MMM + Incrementality that stick → true incremental growth
Full-funnel clarity → marketing + finance + ops in one view
Everything updates live, no spreadsheets required.
Monitor high-level trends or go deep into SKU-level profitability.

epROAS that matters
epROAS is Dema's version of the widely used acronyms POAS and pROAS.
epROAS = how much net profit (after product and delivery costs) you earn per $/£ of marketing spend.
e stands for “expected” as in the expected returns.
P stands for profit, which in this case is Gross Profit 2.
Gross Profit 2 with expected returns is Net Gross Profit 2

Guessing during peak is a losing strategy

Benchmarks that hold up once CPMs surge.
Algorithms primed with incrementality signals.
Confidence to scale spend on proven channels and offers.
With Dema, MMM and incrementality run live in the background, feeding data into finance and growth teams so you enter Black Friday with a tested playbook, not a gamble.
