11 Benefits of Marketing Mix Modeling (MMM) Every Marketer Should Know

"Why should I start using Marketing Mix Modeling?"

I've answered this question hundreds of times during my 15+ years in marketing measurement. And the answer has changed over the years. Marketing Mix Modeling (MMM) used to be something that marketers teams used once a year in annual planning, evaluating high-level budget scenarios. Nowadays, MMM helps performance marketing teams in tactical campaign optimization.

In this blog, we'll discuss MMM's benefits to marketers in 2025.

1. Measure the True Incremental Sales of Marketing

Let's start with the big one. It's obvious but also the most important:

MMM helps you measure the true incremental sales impact of your marketing efforts.

It helps you understand marketing's actual contribution to your sales, compared to other sales drivers, such as seasonality, promotions or weather. It helps you measure which part of the sales was driven by Google and which part was driven by Meta. Or how much incremental sales was generated by your latest Black Friday campaign.

The concept of incrementality, the idea of measuring marketing's true revenue contribution, sits at the heart of modern measurement. The transition from attribution (such as Last-Click attribution) to Incrementality-based measurement, is the single biggest disruption in marketing measurement of the 2020s.

2. Measure the ROI of every Channel and Campaign

When you can measure the true Incremental sales driven by marketing, you can measure marketing's true ROI (Return on Investment). And let's be clear: this is very different from ROAS from Last-Click attribution or Ad Platforms' attribution tools, which are rule-based and not based on incrementality.

Measuring marketing's true ROI enables comparing different activities apples-to-apples: Which marketing activities are actually effective in driving sales for our business?

As an example, I often see marketers positively surprised when they learn how effective their awareness, branding and other top-of-funnel campaigns actually are when they look at MMM-based ROIs for the first time.

Today's MMMs can measure ROI on different levels:

• Media Group: Paid Social, Branded Search, TV, ..
• Media Channel: Paid Social Awareness, Paid Social Prospecting, ...
• Advertising Platform: Meta, Google, TikTok, Pinterest, ..
• Advertising Channel: Meta Awareness, Meta Prospecting
• Campaigns: Meta Black Friday Hats..
• Campaign Objective / Bidding Strategy: Target ROAS, CPC, CPM, ...

💡Example: What does ROI tracking look like in MMM?

While ROI can be visualized in many ways, one common chart is the "bubble chart", which shows the ROI (y-axis), Incremental sales (x-axis) and spend (bubble size).  Below is an example from Sellforte's public demo:

3. Understand Saturation Levels

Every media channel saturates at some point, and MMM helps you understand the level of saturation in each channel. Pouring too much on a channel often leads to showing the ads to the same audience multiple times, and there's only so much they can buy.

Saturation can be analyzed with Response Curves, which capture the relationship between incremental sales that a channel is driving and its spend. In the Response Curve example chart below, the channel has lots of room to scale in Point A, but in Point B the channel is highly saturated and additional investments have very little impact on sales.

Marketing Mix Modeling is the only method that can reliably estimate response curves for media. At the same time, Response Curves are highly critical for optimizing media allocation, which is the next topic we will cover.

4. Drive Growth by Optimizing budget Allocation Across Channels

Let's discuss how MMM actually helps you drive revenue growth!

MMM helps you optimize budget allocation across channels, which is the most common optimization use-case of MMM. The benefit comes from re-allocating spend from channels that are more saturated to channels where there's room for scaling.

Based on our research paper, Unlock 6.5% More Sales with Marketing Mix Modeling, optimizing channel allocation is the third biggest optimization lever and typically helps eCommerce businesses increase sales by +1.6% while keeping the same total budget.

5. Drive Growth by Optimizing Spend Across Campaigns

Let's get more granular: MMM helps you optimize spend level of each campaign. Campaign optimization means that performance marketing teams get recommended budget and bidding parameter change for each individual campaign, and there can be hundreds of them.

It is very common, that for example many Paid Social campaigns get more spend in MMM-based campaign optimization, as they are under-credited by Last-Click attribution by a factor of 2-9x (check our research: How to measure Meta correctly? GA4 vs. MTA vs. MMM).

Campaign optimization is the largest optimization lever, enabling eCommerce businesses increase their total sales by +2.9% (source: Unlock 6.5% More Sales with Marketing Mix Modeling). 

Using MMM to optimize campaign spend is a feature that started emerging in MMM solutions in 2025.  Most MMM solutions don't have this feature, because it requires advanced measurement technology that combines MMM, incrementality tests and attribution data.

6. Drive Growth by Optimizing Budget Pacing

MMM helps marketers optimize their budget pacing, so that media spend is distributed optimally across weeks, preventing for example overinvestment when demand is naturally low and underinvestment when there’s high level of natural demand.

A common pitfall for marketers is to underfund Black Friday campaigns with budget limits, but overinvest in low seasons.

Our research has found that when executed correctly, budget pacing can unlock a +2.0% increase in annual sales for eCom / DTC businesses (source: Unlock 6.5% More Sales with Marketing Mix Modeling).

7. Measure How Marketing Affects Sales in Physical Stores

If you're running an Omnichannel Retail business, you know the frustration: you might be investing 50% of your total budget to digital channels, but you are only measuring how they affect eCommerce sales which might be less than 10% of your total business.

MMM helps your measure how digital channels are driving sales in physical stores, and this can have a significant impact to your measurement.

In a research on Meta and Paid Social more broadly, we found out that offline sales represents 37% - 55% of total sales impact of Paid Social in omnichannel Retail, as summarized by the chart below. This means that you need to multiply Paid Social ROI by 1.6x - 2.2x to capture its full sales impact. The research is available here: How to measure Meta correctly? Part 2: Add offline sales impact.

8. Measure How Marketing Drives Sales in Amazon (and other marketplaces)

If you're a DTC brand, you're likely selling your products in Amazon and other marketplaces in addition to your own eCommerce store. Optimizing the full sales impact of your marketing requires you to understand how your marketing is affecting in all of your sales channels.

In this case, MMM helps you understand how your marketing efforts are affecting sales in your eCommerce store and marketplaces. In some instances, this is also called the halo effect of marketing.

9. Measure the ROI of offline media

Traditional media channels like TV, radio, print, and outdoor advertising remain important drivers of brand awareness and sales, especially for Retailers, but measuring their effectiveness has always been challenging.

MMM helps you quantify the sales impact of offline media.

This capability ensures that offline media investments are evaluated with the same rigor as digital channels, preventing the common mistake of undervaluing traditional media due to measurement limitations, but also holds traditional channels accountable for their ROI.

10. Future-proof your measurement

Here's the uncomfortable truth: traditional attribution and privacy-invasive measurement methods are dying. With MMM, you're building a measurement foundation that'll work regardless of how the privacy landscape evolves.

11. Secure your career as a CMO or Head of Marketing

This might be the most important point for individual marketers. The industry is moving toward greater accountability and more sophisticated measurement. Marketing leaders who understand and can leverage advanced analytics like MMM, are showing that they deeply care about the business results of the company.

In my experience, marketers who embrace MMM tend to have better relationships with their C-suite peers, are more successful in budget discussions with the finance team, and get more career advancement opportunities.

3. Why is Marketing Mix Modeling (MMM) better than Last-Click attribution?

Last-Click attribution gives full credit for the conversion to the last advertisement clicked by the user before purchase. This means that it overestimates the effectiveness of bottom-of-funnel channels that are close to purchase, and underestimates top-of-funnel channels and middle-of-funnel channels, such as Paid Social or Paid Video. MMM gives proper credit to each channel across the funnel, based on their performance in driving incremental sales.

Learn more about the shortcomings of Last-Click in our blog The 3 Danger Zones of Last-Click (And How to Avoid Them).

4. Why is Marketing Mix Modeling (MMM) better than Ad Platforms' pixel-based attribution?

Advertising Platforms' attribution methods are not able to distinguish between conversions that would have happened without advertising, conversions that were really driven by other platforms, and conversions that were actually incremental due to advertising on the specific ad platform. MMM is able to measure the true incremental sales of each ad platform.
