Attribution models sound like a smart way to allocate credit to your different ad campaigns. But, they're inherently built from flawed and incomplete data, meaning that it's impossible to assign credit to the right campaigns. This means that they are almost certainly making you draw the wrong conclusions. Rich is going to explain how you change that, and break down how incrementality models can help you make better decisions with your creative, your strategy and your media buying Key Takeaways: - Attribution and Measurement are different things - Attribution is not sufficient for measuring the impact of your marketing campaigns - Increasing privacy thresholds mean that it will only get worse at this - Incrementality, captured through several methods, is the most powerful method at our disposal to capture and deliver growth

3. Let’s start with some definitions

4. Attribution
Directly connecting an individual or cohort to the
marketing activities they’ve engaged with.
Incrementality
The actual impact that a marketing activity has
on a KPI, and which would not have happened
without it
Measurement Modeling
Using statistics and machine learning to find
correlations and signals that can describe the
incremental impact of marketing activities.

5. The first responder: The nervous
system of our marketing
campaigns
Attribution:

6. GA4 is a good example of an attribution
channel*
*and there are lots of others

7. …and DDA sounds great, right?
[Data-driven] Attribution uses machine learning
algorithms to evaluate both converting and non-
converting paths. The resulting Data-driven model learns
how different touchpoints impact key event outcomes.
The model incorporates factors such as time from key
event, device type, number of ad interactions, the order
of ad exposure, and the type of creative assets. Using a
counterfactual approach, the model contrasts what
happened with what could have occurred to determine
which touchpoints are most likely to drive key events. The
model attributes credit to these touchpoints based on
this likelihood.”

8. But,
there’s a few pretty fundamental issues…

9. Where attribution models fall down
They only
know when
people have
clicked an ad

10. Where attribution models fall down
Privacy (e.g.
SKAN)

11. Where attribution models fall down

14. What impact does this have?
Take a look at your first and last click attribution
report
And… how many people are coming directly to your site?
Well…

15. Attribution is a first
responder. It’s your
campaign’s nervous
system. It’s great for
instrumentation
Attribution is actually
great for some stuff

16. Where attribution models fall down

converted anyway?

17. The solution?

… and which wouldn’t just have happened anyway 2

18. It doesn’t care about individuals
It looks at cohorts and aggregates. No tracking? No
problem.
What does an
incrementality-first
approach do?
It doesn’t care if someone clicked or viewed
It looks at outcomes, not the journey
It tracks actual impact
It compares what actually happened against a
counterfactual: What was your impact?

19. So how do you measure incrementality?
Source: Towards Data Science - Power Analysis for Data Scientists
https://towardsdatascience.com/power-analysis-17636d3f059b
You run a test
We need two things:
1) We need results with our
marketing present, and results
without our marketing present
2) We have to be confident of
effect size

21. You could also look at alternative data
sources
For example: “How did you hear about us?” surveys

22. Or take this straight to MMM*
(*Media Mix Modelling)

23. MMM aims to reattribute based on
incrementality

24. MMM requires a large number of inputs
You need:
Historic data
+
Building*
+
Know-how*
*We can provide those parts dw

25. Each of these has a part to play
Speed Comparability Accuracy
Attribution
Surveys

26. Sweet, so how do I use
Incrementality?

27. Thinking in terms of
incrementality
opens a lot of doors

28. Channel X says it’s doing a lot. Is it?
Or is it just getting in front of people
before they buy?
It shows where you need
to fix bad channels

29. You can’t measure the
impact of brand
awareness with
attribution
You can with
incrementality
Incrementality enables full funnel
marketing

30. All of your spend is going
to statics, you say? Those
things that are great at
driving clicks, you say?
It lets you measure
creative impact

32. Measuring the actual impact of your marketing…
+
Operating across the funnel
+
Focusing
on incremental revenue
Incrementality lets you GROW

33. Key takeaways
1. Attribution and measurement are different things
2. Attribution will only get worse
3. Good attribution enables good instrumentation, good
measurement enables good strategy
4. Incrementality, is the most powerful method at our
disposal to measure impact
5. When you know what is delivering impact, you know how
to grow
