- ROAS is a commonly used metric but does not accurately correlate to profitability. It should not be used as a proxy for profit.
- The "messy middle" of the customer journey involves complex cognitive and behavioral factors that influence purchase decisions beyond just ad clicks.
- Connecting click and purchase data through techniques like click-ID reporting allows understanding of true campaign performance and identifying high-profit products and combinations to optimize campaigns.

1. The ROAS Pathology
2. The Messy Middle
3. Two Birds, One Stone
4. The Holy Grail
5. ROAS = conv. val / cost
A broadly-applicable proxy for profit
● Easily and universally calculable
● Works across all campaign entities
● Reportable from hourly up to yearly
● Google formula is open-ended
and why is it so popular?
What is ROAS
6. Proxy Metrics
A proxy metric is an indirect measurement of a desired outcome, typically used
when the desired outcome cannot be directly measured or observed. The proxy has
value because of its correlation to the goal – and the higher the correlation, the
higher the value or effectiveness of the proxy will be.
7. ROAS is a channel-siloed metric
● How accurately is ROAS
modelled to profit?
● What steps can we take to
improve that modelling?
8. Measurement pains increase as incremental returns flatten
● How accurately is ROAS
modelled to profit?
● What steps can we take to
improve that modelling?
● What steps can/should we take
to replace ROAS?
9. What’s in a name?
A ROAS by any other name would smell as sweet
10. Look to ACoS for more rational conversations
● Calculated with the same elements as ROAS: cost and conversion value
● Name clearly describes what it is – a campaign efficiency metric
● Harder to confuse with profitability

cost / conv. val = ACoS

RANGE CONSUMPTION
16. From quantitative and narrow, to broad and subjective
The ‘messy middle’ [is] a
space of abundant
information and unlimited
choice that shoppers have
learned to manage using a
range of cognitive shortcuts.

17. Browsing and consumption are primal behaviors
● Consumers cycle through exploration and evaluation phases – repeatedly gathering and reducing options
● For merchants, there are opportunities arising from deep-seated biases manifested while shopping

23. A few questions along the way
● What is the real profitability of my Shopping Ads?
● In which quantity are products sold and at which price?
● Which products drive revenue, which products drive order profit?
● Which items often act as replacement products?
● Which products are often bought together?

Gross profit
calculation
● Calculate the order profit regularly for every transaction
● Gross profit = Revenue - COGS ( - Transactional costs, optionally)
● Connect the conversion with an adclick (Click-ID)
Offline conversion
Import
Unlock order profit for optimization
● Regular upload of offline conversion feed to Google Ads
● The feed features: Click-ID, conversion time, conversion value, currency
Goal
Adjustment
● Rethink and adjust your goal setting, your current ROAS goal won’t fit
● Ensure that all stakeholders are on board, optimization based on profit ≠
optimization based on revenue
30. Challenges while planning and performing this task
● Large data volumes
● Data availability, timeliness, and fallbacks
● Intra-day price changes
● Conversion lag
● Returns and refunds
