The digital marketing landscape has undergone dramatic changes in recent years. Privacy regulations, such as GDPR and CCPA, alongside browser restrictions on third-party cookies, have fundamentally shifted how brands measure the effectiveness of their marketing campaigns. As we are moving towards 2025, the era of cookieless attribution has arrived, forcing marketers to seek alternative approaches to track performance. Enter Marketing Mix Modeling (MMM), and more specifically, scalable regional MMMs. This new kid on the block is a solution that not only meets the needs of modern marketing attribution but also thrives in this new environment.

In this blog post, we’ll explore why traditional attribution models are no longer viable, how MMM can bridge the gap, and how our platform, Alviss AI, leverages cutting-edge technology to refit models daily at scale to deliver high-quality insights that help you optimize your marketing spend.

The Demise of Cookies: A Brief Overview

Cookies have been a cornerstone of digital marketing attribution for more than two decades. With the ability to track users’ behavior across the web, cookies enabled advertisers to follow the customer journey in granular detail, assigning credit to various touchpoints. However, with growing concerns around privacy, companies like Apple and Google have either limited or are in the process of phasing out cookie-based tracking.

This shift has left marketers in a lurch, as many rely on third-party cookies to determine which channels and tactics drive conversions. Without cookies, the need for a privacy-compliant and robust attribution solution is more urgent than ever.

Enter Marketing Mix Modeling (MMM)

Marketing Mix Modeling offers a cookieless alternative that is based on statistical analysis of how various marketing activities (both online and offline) impact sales over time. Unlike multi-touch attribution (MTA), which depends heavily on user-level data, MMM uses aggregated data, such as media spend, to infer the contribution of each channel.

MMM doesn’t require individual-level tracking, making it naturally compliant with evolving privacy regulations. More importantly, it works across all channels, including those that never relied on cookies (e.g., TV, radio, print), providing a holistic view of marketing performance.

Why Scalable Regional MMM is the Future of Attribution

While MMM is an attractive option, implementing it effectively at scale presents its own challenges. National-level MMMs are common, but they fail to account for regional variations in marketing effectiveness. For instance, a campaign that performs well in one city may underperform in another due to local market dynamics, cultural differences, or regional competition.

To solve this, regional MMMs break down the analysis into smaller geographic areas. This level of granularity allows marketers to:

  • Identify hyper-local trends that national models might miss.
  • Optimize spend at a regional or even city level.
  • Customize messaging and channel strategies based on local audience behavior.

But here’s the catch: building regional MMMs requires massive amounts of data and the ability to run models at scale, frequently refitting them to account for new data. Traditional MMM approaches often involve long time lags between model updates, making it difficult to adapt quickly in a fast-changing marketing landscape.

This is where Alviss AI stands out.
