THE ESSENTIAL GUIDE TO MMM AND MTA
Executive Summary
As the digital ecosystem rapidly evolves, Multi-Touch Attribution (MTA) is gaining noticeable traction among
forward-thinking digital players in our industry. Many advertisers, however, have been using Marketing Mix
Modeling (MMM) for much longer and are hesitant to move beyond this tried and true methodology.
For a detailed definition of MTA and MMM, please see Appendix I
The conversation is ongoing over which of the two is better, with arguments ranging from turnaround time to
granularity, cost, and actionability. Despite the debate, we believe that these two approaches are not mutually
exclusive and could be complementary when used correctly. In fact, several companies have applied their
own unified approach to combine the benefits of both MMM and MTA. However, confusion persists among
many marketers and other stakeholders as vendors do not have a common definition of a unified approach.
To address this topic, the IAB Measurement &
Attribution Committee assembled a working group,
conducted an industry-wide survey, and convened an
expert panel to understand the adaptation and the
applications of these two approaches to bring clarity
to the marketplace confusion.
This paper focuses on answering the following:
• Why and how to use MMM and MTA together
• What to expect from MMM and MTA including
restrictions, and tradeoffs
• How to choose a solutions provider
Rather than endorse any specific approach, we
aim to empower our members with knowledge and
transparency so each marketer can make their own
informed decisions.

THE ESSENTIAL GUIDE TO MMM AND MTA
Outcome-Based Measurement: Focusing on the Business Bottom Line
A panel of experts convened by IAB highlight an important aspect of outcome-based measurement: It
provides a simple number that allows CMOs to prove to their boards the value of marketing efforts, and it
allows marketers to speak the same language with stakeholders across their business.
“
Measurement is critical to ensure that what we’re investing in is moving
the needle for our brands. Even more important is setting the right KPIs.
A KPI shouldn’t be a media delivery metric such as impressions or reach
that can be easily bought. Meaningful KPIs need to align with marketing
objectives and define what success looks like through the development
of learning agendas.
Jessie Dawes, Vice President, Media and Digital Marketing, Shiseido
Media effectiveness has historically been measured in terms of delivery metrics like reach, frequency,
and Gross Rating Point (GRP) — with results often sitting outside of a comprehensive and consistent
measurement framework. This has made it difficult for marketers to measure the impact of their marketing
investment in a cohesive way. However, within the digital media space we can measure both media delivery
(reach, frequency) and performance metrics (conversion rate, engagement) together so that we can link
performance, reach, and revenue into a single view of media investment and how it drives growth. This is the
ideal scenario. However, since some of these metrics do not directly translate to the business bottom line, it’s
not always possible — and this keeps executive teams up at night.
“
Measurement is not just about collecting data and reporting on metrics.
If what you report is not connected to the campaign objectives, overall
business goals, or connected to solving for a business question, you are
missing an opportunity. Outcome-based measurement pushes marketing
to align closer with the overall business and not only improves results but
also helps drive analytic adoption throughout an organization.
Maggie Merklin, Executive Vice President, Analytic Partners
The industry has been shifting its focus from vanity metrics such as click-through rate (CTR) to outcome-
based measurement as the latter ties media performance to the metrics that are crucial to a business’
growth. This enables marketing leaders to assess the performance of their media investments with clearly
defined financial-related metrics such as sales or store visits. In other words, this empowers marketers to
5
THE ESSENTIAL GUIDE TO MMM AND MTA
better understand where their media investments are driving growth and plan for future investments in a
more data-driven way. Furthermore, outcome-based measurement and reporting build consistency and
familiarity over time for marketing leaders, strengthens a business’ ability to plan and evaluate all their
marketing investment options by making results accessible and easy to interpret.
“
Marketing starts with knowing our customers so that we can anticipate
their needs and deliver the right message at the right time. We believe
it’s important to measure all channels with an ROI mindset. Through
the use of measurement tools like media mix modeling and multi-touch
attribution, we are better able to understand the performance of each
channel and, as a result, we’re able to make decisions that improve
marketing effectiveness and efficiency.

THE ESSENTIAL GUIDE TO MMM AND MTA
Industry Performance Benchmarks
While MMM has been used for decades in marketing measurement, MTA was developed when digital media
became popular. As with every relatively new measurement method, there have not been many benchmarks
available to the industry.
Industry benchmarking can be a tricky subject, especially when applying various techniques to quantify ROI.
There are a variety of factors that affect the amount of marketing-driven sales that will be quantified in a
measurement solution, including the product category, sales, and media channels, amount of marketing
investment (both absolute and as a percent of sales), data availability, data freshness, and many more.
Reconciling the measured ROI performance within a brand’s marketing ecosystem can be further complicated by
the number of data and media partners that have their own bespoke methodologies. This proliferation of single
channel, single partner, limited data measurements is driving brands to a standardized, cross-channel solution.
During the panel discussion, it was agreed that regardless which technique, brands switching to a new
measurement vendor often report double-digit returns in marketing investment performance, reflecting the
lack of a true baseline comparison. Our expert panel shared their perspectives: We have seen MTA studies
claim that the performance improved from 3% to 30% or higher. 30% seemed to be on the higher side, yet still
possible, especially in a new study, with a new vendor where a baseline is lacking. However, the greater the
number is, the harder it is to sustain.
Most of our panelists agreed that 3 to 4% is more realistic, especially in an ongoing study.
As for MMM vs. MTA, MMM tends to produce higher marketing contribution measurements. This is primarily
because it can include more touchpoints than MTA, especially offline non-addressable tactics such as TV ,
radio, out-of-home (OOH), point-of-purchase (POP), and sales promotion. When comparing the benefit of
MMM and MTA, there are tradeoffs to each technique. MMM tends to provide more measured marketing
ROI because it can include more touchpoints and provide an understanding of how to improve ROI. MTA
provides more tactical understanding of how to improve ROI, but for fewer touchpoints.

THE ESSENTIAL GUIDE TO MMM AND MTA
Reasons Marketers Use MMM and MTA
In addition to validating marketing ROI to clients or management, many survey respondents shared that they
use MMM for prediction and planning/budget allocation. In their own words:
As for MTA, most respondents use it to measure digital campaigns:
“
We use MMM to decide which categories get
advertising dollars and also what media tactics will
be used category by category.
“
We often might shift our spending based on
information from MMM and also use this to justify
advertising dollars for the next quarter or year.
“
We make spending and
allocation decisions. We also
make investment decisions in
terms of incremental spend.“
We prioritize MMM results after each read-out to
help drive channel allocations and optimizations.
This is a significant factor in how our planning team
designs a given plan and allocates media budget.
“
We use the media mix model
in our toolset to tell us big ...
budget allocation questions.
“
For digital budget allocation. “
Digital investment, short term.
“
To get digital test reads. “
Qualitatively to inform digital tactics in conjunction
with other learning (e.g., MMM results).
“
Helps us understand our down-the-funnel metrics
and impact and how to allocate our future funds —

THE ESSENTIAL GUIDE TO MMM AND MTA
Challenges and Benefits of Using Both MMM and MTA
“
In MTA, we might see paid social is down year-over-year, then with MMM
we’re getting a completely different picture, that paid social is doing
tremendously well.
It requires a lot of discussion to make sure the team understands MMM,
the boundaries of MMM, the scope and how that differs from MTA, and,
for us, we’re approaching them as separate data sources to inform our
decisions.
Jessie Dawes, Vice President, Media and Digital Marketing, Shiseido
Most survey respondents and expert panelists mentioned that they use MMM and MTA for different purposes
— and that the results often do not match. Marketers saw conflicting information and struggled to marry
the learning from both in a meaningful way. Some mentioned that they have different teams owning each
measurement and that they don’t integrate data from both studies.
“
We use MMM for an overarching view of performance; MTA is mostly
focused on digital, where it can be most effective. And then we measure
how digital is moving and changing over time in the media mix model
(with optimizations based on MTA).
Lindsay Blanch, SVP , Head of Decision Science, Hill Holliday / Trilia Media
Some of our panelists believe that MTA alone is a flawed approach and that the way to address the issues is
with a unified approach. However, while a unified approach solves the challenge of having multiple vendors
and reports that are not well aligned, planning and implementation become more complex. For specifics,
please see the section called Understanding the Restrictions and Tradeoffs.

THE ESSENTIAL GUIDE TO MMM AND MTA
When Not to Use MMM or MTA
While MMM and MTA have different setup criteria, use different datasets, and apply different methodologies,
they do share some commonalities: Both approaches need careful analytic design, proper implementation,
and someone to interpret the results and apply the learnings to future plans. Without proper resources, there
is a high likelihood of failure.
Specific constraints for MMM and MTA include the following:
Scale
For MMM to obtain results that are meaningful and actionable, the marketing investment needs to reach a
certain scale. While most people agree with this concept, there’s no agreement upon a minimum threshold.
Some long-time veterans suggest 50-100 GRPs if the advertisers are using network TV , depending on the
length of the flight. However, it does not apply to advertisers who do not use national TV since iGRP does not
translate the same.
For MTA the threshold is lower since it measures fewer touchpoints and it can be set up on a campaign
level instead of a multi-year modeling dataset. Nevertheless, there are other trade-offs of scale. In MTA, the
complexity increases with the scope, from the number of media channels and platforms to different KPIs, to
the overall size and the duration of the campaigns. For more information, see the sections below for Media
Mix and Offline Metrics.
Budget
While the cost of implementation and support vary, no one has ever said running MMM or MTA is cheap. Our
survey results revealed that cost was one of the common pain points for both MMM and MTA for advertisers.
However, when compared to the overall marketing budget, the cost of measurement can be relatively low. One
general reference suggests that MMM isn’t worthwhile if the annual budget is less than $5 million for a minimum
of two consecutive years, whereas MTA may be supported on a campaign basis only as part of ROI planning. Of
course, this is a rough estimate and there are other conditions things to consider, such as media mix.
Media Mix
MMM works when there is variation in media mix, but not such drastic variation that it’s outside of historic
bounds, especially when the results are to be used for future planning. For example, if the media mix is a
continuous flight with the same weight for each platform, MMM is not the right approach. Nor will it work
if there’s a drastic change to the media mix, say from 70% TV and 30% digital to 90% digital and 10% TV , as
there will be no benchmark for the model to function.
On the other hand, MTA works well for many digital campaigns due to its trackability. One of the most
challenging aspects, however, is working with walled gardens such as Google, Facebook, and Twitter since
third-party measurement providers won’t have visibility into user-level impression data inside the walls. If the
media plan has a sizable portion in these walled gardens, the solution for walled garden measurement will be
well-executed A/B testing and/or MMM.
10
THE ESSENTIAL GUIDE TO MMM AND MTA
What’ s the best way to manage walled gardens?
“
Shut it off for a while. Variability is our friend. Test increased weight
levels, test decreased weight levels, shut it off for a month and see what
happens. We try to build as much ‘test and learn’ and as much variability
as we can into our media plans.
Lindsay Blanch, SVP , Head of Decision Science, Hill Holliday / Trilia Media
Offline Metrics
MTA was originally designed to track digital exposures to digital conversions. However, few brands are
allocating 100% of their budget to digital. There are several challenges to accurately tracking online and
offline media and conversions to the same individual (i.e., identity resolution) from insufficient data, shared
devices, and cookie rejections, to flawed matching methodologies. While it is possible to apply MTA to an
online/offline campaign with both online/offline KPIs, it adds more complexity and potentially increases the
error rate from misattribution.
11
THE ESSENTIAL GUIDE TO MMM AND MTA
Understanding the Restrictions and Tradeoffs: Data Collection, Data Governance,
Identity, Walled Gardens, and Privacy
Data Collection
A robust data collection plan is imperative for any measurement solutions (“garbage in, garbage out”). The
biggest hurdle to timely delivery of insights across MTA and MMM is often delivery of accurate data. Not only
do data restatements delay results and disturb model accuracy, they also add costs by way of rerunning or
restating results. Delivery issues are particularly pronounced for MTA since results are delivered and used
daily or weekly, while MMM results are typically delivered monthly or quarterly.
Strong incoming data delivery practices are required for both MTA and MMM to ensure data accuracy.
Frequently occurring data issues like spend actualization for TV and radio media types can be dealt with
systemically. Where delays occur due to spend actualization, planned spend can be used and adjusted
appropriately until the actualized data is ready to replace it.
When setting up MMM and MTA solutions, consider all possible data sources. Typically, there is a tradeoff
between completeness, time to deployment, and solution complexity. For MTA it may be straightforward
to gain access to traditional browser-based ad exposures, but mobile/in-app inventory, over-the-top (OTT)
exposures, walled gardens, and non-digital addressable data each present their own challenges.
A user of MTA must consider their entire marketing budget and understand that the fastest-to-deployment
solution may only cover a fraction of media spend. A solution built in phases can find a balance between
completeness of data sources and time to deployment, where the lowest-hanging fruit is built first, and
harder to access data sources are added in the future. What becomes critical with this approach is a
modeling methodology that accounts for the to-be-added marketing channels.
On the MMM side, the same tradeoff between completeness and time to deployment exists, however the
pain points tend to lie in capturing adequate historical data. Generally speaking, MMM requires roughly three
years of historical data across media types and model outcomes (KPIs). In many cases, however, history is
lost or was never recorded. As a result, media which is just being tested in market is hard or impossible to
read. MMM often focuses on large time-period data deliverables with measurement at the media channel
level. Running the analysis with an overly simplistic data delivery format can obscure underlying data issues,
like a missing media type, campaign name, or other variables. Applying the right data filters during a data pull
(and checking this data) becomes critical to an accurate model.
Data Governance
As MTA solutions become more complex and data sources proliferate, a rich suite of data validation and
audit reporting tools are critical for success. This suite must automatically flag data issues and raise them to
relevant parties, as well as provide easy-to-digest human-readable reports so any user can perform a high-
level health check on the data collection plan, similar to solutions in place for MMM today.
12
THE ESSENTIAL GUIDE TO MMM AND MTA
Identity
Due to the omnichannel nature of modern marketing plans, identity resolution is a critical piece to any MTA
project. Cookie-based measurement, while still useful, tells an incomplete story. The most successful MTA
projects are built on an identity graph that allows marketers to tie their easily trackable digital addressable
channels, walled garden platforms, offline addressable channels, and first-party data to a single identity
graph through personally identifiable information (PII) onboarding and direct integrations with platforms.
While dozens of companies claim that they have developed a great solution, there are gaps yet to be
addressed.
Walled Gardens
Walled gardens have been difficult to measure, but times are changing. Platforms like Google, Facebook,
Twitter, and others have historically been protective of their user-level data in the name of privacy and allow
marketers to granularly measure performance only within the context of their platform.
A/B testing and macro-level measurement (e.g., MMM) has always been possible for walled garden
advertising. However, recent developments in data clean rooms and advertiser demand for transparency have
slightly opened the door for granular measurement. A select few measurement vendors have established
relationships with these platforms to enable transparent cross-channel measurement.
Privacy
We live in a rapidly evolving privacy landscape. General Data Protection Regulation (GDPR), the California
Consumer Privacy Act (CCPA), the NAI 2020 Code of Conduct, and browser makers’ war on third-party
cookies is making granular measurement more difficult than ever. The measurement industry must respect
consumers’ privacy preferences while at the same time work within the new regulations to create useful and
actionable measurement solutions. MMM deals primarily with de-identified and aggregated data sets, so the
effects of the new privacy landscape are mostly limited to MTA projects.
Trackability of users across digital properties is significantly degraded in this new privacy landscape,
especially when technologies rely on traditional browser-based third-party cookies. Innovative tracking
technologies like browser fingerprinting can help marketers temporarily mitigate the limitations but at the
expense of their users’ privacy. There are other methods like first-party PII onboarding and probabilistic
clustering that can help as well. Marketers must weigh the tradeoffs when making decisions about their
measurement tech stack.
In the larger view of a consumer or customer’s identity, we believe that an industry-wide standard is
necessary to successfully continue to measure and act on identity. That is why the IAB is currently working
with all the identity consortiums, as well as the browser makers, to come up with a democratized solution
that benefits both advertisers and consumers.
What is needed is a holistic solution that is privacy compliant: A solution that provides relevancy and enables
meaningful connections between advertisers and consumers without creating an identity arms race across
the ecosystem; a solution that enables robust privacy controls that the consumer can manage on their end.

THE ESSENTIAL GUIDE TO MMM AND MTA
Choosing the Right Vendor for Measurement
Choosing the right vendor(s) is critical to driving campaign, marketing, and business success. Given the
evolving landscape and breadth of providers across MTA and MMM, it’s important to ask the right questions
before diving in. Key areas to investigate include:
Vertical Knowledge and Experience
Vendors should work with advertisers to understand their industry. While some measurement basics are the
same across industries, developing hypotheses about what influences sales requires specific knowledge. This
experience also allows for more accurate inclusion of the most important drivers of sales in the model. The
more comprehensive a model is, the more likely it will accurately attribute influence on the right touchpoints.
Vertical experience is often seen in a vendor’s benchmarks. Robust benchmarks come from deep experience.
Transparency and Clarity of Modeling Approach
Understanding how a vendor developed their model and its inner workings makes it easier to understand its
distinct point of view, limitations, and the results. Vendors should be willing to explain in detail their approach
and even open their black box to show how their metrics work. Many vendors publish all or parts of their
approach to allow peers to scrutinize and improve on it.
Granularity, Accuracy, and Access to Data
How deep and wide is the data pool, how correct is it, and how automatically does the vendor collect it?
This is the meat and potatoes of measurement, but these elements make up most of the meal. Does the
vendor have direct access to data and the right partnerships? Does the vendor use a single, centralized
analytics platform? Is the data granular enough to make actionable decisions (e.g., store-level data versus
a geographic area)? What regular testing does the vendor do on the data to ensure errors (there are always
errors) are caught, corrected, and eliminated before reporting?
How Actionable Are the Insights
Gone are the days when reporting on what happened is enough. Today, all measurement needs to point to
what’s next, and it needs to be specific enough to drive strategy and allocation. Specific insights around
campaigns, tactics, brands, distributors, or geographies can drive specific actions and improve results.
Reports that show what happened at too macro a level don’t allow teams to tease out what is really driving
results or how to optimize performance.
14
THE ESSENTIAL GUIDE TO MMM AND MTA
Conclusion: The Evolution Continues
The digital revolution has unleashed enormous new measurement and attribution capabilities, with some
predicting that the industry would quickly achieve the holy grail of understanding precisely which ads and
media spur web and store visits, purchases, customer engagement, and more. After all, the advertising and
marketing industry had never seen such an impressive application of data, technology, and investment in such
a short period of time.
The reality is more complicated. That same revolution has also brought enormous complexity. And, as with
all revolutions, it hasn’t slowed down long enough for the current challenges to be addressed before new
ones arrive.
Success in this world should be measured in how far we have come, not necessarily how far we have to go,
and the industry’s capabilities in measurement and attribution have come a long way indeed. This can be seen
across the ecosystem, but perhaps most acutely in how the relationship between MMM and MTA has evolved.
Industry leaders continue to vigorously seek the attribution holy grail, now more than ever with a more unified
understanding of how both MMM and MTA can contribute.
15
THE ESSENTIAL GUIDE TO MMM AND MTA
Appendix I
MMM, MTA, and Unified Measurement Models Defined
Marketing Mix Modeling (MMM)
Established in the 1960s, Marketing Mix Modeling or MMM is a statistical analysis of aggregate sales,
marketing, and business drivers data that quantifies the impact of different marketing channels and tactics
(the marketing mix) on financial outcomes over time. The result is insights and recommendations that can be
used to optimize marketing investment allocations and predict future outcomes.
MMM attempts to answer questions such as: “What was the return on ad spend on mobile last year?” and
“What would sales be if we shift 10% of the budget allocation to addressable TV?” Since MMM measures
results on an aggregate level, it can include marketing tactics that are not addressable such as radio or
broadcast TV .
Multi-Touch Attribution (MTA)
The ultimate goal of Multi-Touch Attribution or MTA is to properly measure the impact of marketing activities
on the metric associated with a conversion event at a granular level and to use these insights to guide
decisions about future marketing spend. The fundamental question that MTA seeks to answer is “What is
the expected change in propensity to convert that was the result of an impression (or any form of interaction
with the customer)?” This measurement must also consider the innate propensity that different customers
will convert (e.g., purchase) without any exposure to marketing.
Many attribution methods are based on predetermined weights that are used to proportionately assign credit for
converting events (e.g., purchases) to the marketing treatments preceding it. Simple weight-based allocations
like first- or last-click, equal attribution, or time-dependent weights do not get to true incrementality.
Unified Measurement Model
A new marketing measurement approach that integrates multiple statistical techniques, such as, but not
limited to MMM and MTA, to assign business value to each strategic and tactical factor affecting marketing
performance across all customer touchpoints. It resolves the differences commonly seen when MTA and
MMA are used separately.
There are several ways to build a unified measurement model; one approach is a three-step implementation
process involving MMM models that inform MTA and are recalibrated to ensure consistency.
In the first step, marketing mix models are created, quantifying the impact of addressable and non-
addressable business drivers. In the second step, an MTA model is built using inputs from the MMM. The
non-addressable impacts are fed into the MTA model to control for non-addressable drivers. The addressable
coefficients from the MMM model are used to calibrate the estimation of the MTA coefficients. The third step
in the process is the alignment of coefficients of the addressable media across the MMM and MTA models to
ensure consistent measurement.

Discovery: What Users Say About MMM and MTA
To better understand how MMM and MTA are perceived and used, the IAB Measurement & Attribution Committee
conducted a fact-finding survey to gauge usage, familiarity, benefits, challenges, pain points, and future plans for
MMM and MTA. The study collected responses from 116 advertisers, agencies, media/publishers, and marketing
companies from November 2018 to January 2019. Based on the survey results, we learned that:
• MMM is more broadly adopted than MTA, especially among advertisers.
• Cost, knowledge, data collection, data quality, and transparency are common pain points for both
approaches.

THE ESSENTIAL GUIDE TO MMM AND MTA
Key Learnings
Marketers are more familiar with MMM. Survey results indicated that our respondents are more familiar
with MMM than MTA, especially among marketers (advertisers and agencies). While the confidence among
marketers seemed high, we did notice a repeated theme of knowledge and transparency cited as common
pain points regardless of respondent backgrounds. It supports our approach of education, clarification, and
simplification as the base for reconciliation.
MMM is also more adopted than MTA. Overall, MMM
is more adopted among our respondents than MTA.
And marketers are more likely to use MMM than
other industry players.
This finding, along with the level of familiarity and
common pain points, established a solid base for us
to collaborate and reconcile MMM with MTA.

THE ESSENTIAL GUIDE TO MMM AND MTA
The high cost of adoption and lack of knowledge, data collection, data quality, and transparency are the
common pain points for both MMM and MTA.
• While marketers like the holistic approach for MMM, especially when it comes to budget allocation, there
are some pain points too including cost, timeliness, and not enough granularity.
• When it comes to MTA, understanding the consumer journey was mentioned repeatedly as a benefit.
However, the lack of transparency, lack of understanding, and questionable methodology were called out
as a disadvantage, in addition to its focus on digital media only and its lack of offline attribution.
• The lack of transparency in the methodology was mentioned under both MMM and MTA as a reason for
not using either approach.
• While lack of understanding could be the overall barrier, for respondents who are familiar with both, the
hurdle of reconciling MTA learnings with historical learnings and MMM insights is the key to adopting both.
