Since the implementation of the EU’s General Data Protection Regulation (GDPR) in 2018, the widespread use of cookie consent banners has become a global norm, requiring explicit user consent before websites can track data. While this framework aimed to bolster user privacy, it has also introduced notable challenges for both marketers and users. Marketers have faced difficulties in collecting comprehensive data for accurate attribution and retargeting if visitors withhold consent, disrupting marketing measurement tools. Meanwhile, users often encounter frequent cookie pop-ups, which can detract from a seamless browsing experience.

Looking ahead, the European Commission has introduced the Digital Omnibus proposal, a legislative package announced in November 2025, which promises broad changes affecting data privacy laws in the EU. This initiative, set to reshape how digital consent is managed, could have significant implications for businesses operating both within and beyond the EU’s borders. According to BrowserMedia’s detailed analysis, the proposal is not merely about cookies but includes a wide-ranging effort to modernise digital regulation, aligning consent management with the evolving landscape of digital technologies, including artificial intelligence (AI).

A central element of the Digital Omnibus is the overhaul of the cookie consent framework. One of the standout changes is the move toward integration of cookie settings within browsers and operating systems. Instead of encountering a multitude of individual cookie banners, users will be able to set their preferences once at the browser level, which websites must honour for six months. This shift has the potential to significantly enhance user experience by reducing the frequency of interruptions while navigating different websites. However, this also means marketers might have to adapt to managing consent signals at the browser level rather than relying on interactions with individual cookie banners, posing new tracking complexities especially given divergent approaches from browsers like Chrome, Safari, Brave, and DuckDuckGo. Some of these browsers already impose stringent blocks on third-party cookies, potentially limiting data collection further.

Controversially, the Digital Omnibus proposes a shift from an opt-in to an opt-out model for certain types of tracking cookies. Currently, explicit consent is required before tracking cookies can be set, but under the new proposal, tracking may be established by default with users needing to actively opt out if they wish. While this could ease data collection for some marketers, it raises privacy concerns, as users may be tracked unless they take steps to refuse. Moreover, privacy-centric browsers might still block tracking despite legal allowances, complicating the landscape. The legislation plans to categorise cookies by risk, implying that explicit consent will still be mandatory for high-risk, marketing-oriented cookies.

Another notable change involves expanding the use of ‘legitimate interest’ as a legal basis for processing personal data, currently subordinate to explicit consent for most marketing activities. The Digital Omnibus would allow businesses to rely on legitimate interest assessments (LIAs) to justify some uses of tracking cookies, provided they balance their interests against user rights, maintain clear opt-out options, and document their processes thoroughly for potential regulatory scrutiny. This pivot has sparked debate, as it may dilute the primacy of user consent, raising concerns about possible overreach in data exploitation.

Further complicating the data privacy landscape, the proposal seeks to narrow the definition of special category data, sensitive personal information such as health status and political beliefs, to only data that directly reveals such information. Under the current regulations, even inferred data relating to sensitive categories is protected. Marketers might benefit from this redefinition by gaining more flexibility in using inferred interest data for targeting, but critics warn it could undermine protections for vulnerable groups. For example, the risk of sensitive targeting leading to harmful scenarios, such as exposing vulnerable individuals to coercive or manipulative advertising, remains a serious ethical concern.

The timeline for these reforms is expected to be extensive. The proposal now proceeds to the EU’s ordinary legislative process involving the European Parliament and Council, where substantial amendments are anticipated. Given the often slow pace of digital regulation, illustrated by the ongoing delays surrounding the ePrivacy Regulation, full implementation could take several years. Additionally, browser-level integration adds another layer of complexity, requiring compatibility across major browsers to ensure a uniform user experience.

Marketing professionals must start preparing for potentially significant changes. The proposed reforms could complicate multi-touch attribution models if consent rates decline or browsers adopt stricter default privacy settings. This could lead to a reliance on last-click attribution or alternative measurement techniques such as marketing mix modelling and incrementality testing to compensate for gaps in digital data. Retargeting campaigns could see audience sizes shrink, impacting the granularity and efficiency of personalised marketing efforts. Moreover, the need to conduct and document lawful interest assessments rigorously introduces new compliance burdens.

Adapting to these changes also means revisiting technology and data strategies. Google’s Consent Mode and similar platform-specific solutions will need to evolve to interface effectively with browser-level consent signals. Server-side tracking and conversion APIs may become more critical to maintain data accuracy amid browser restrictions. Meanwhile, marketers will likely refocus on first-party data collection, leveraging customer relationship management (CRM) systems, loyalty programmes, and direct user engagement tools such as preference centres and surveys. The role of zero-party data, information users explicitly share, will become paramount as third-party tracking faces increasing constraints.

On the broader regulatory landscape, the Digital Omnibus is part of a package that also delays certain high-risk provisions in the EU’s forthcoming AI Act to December 2027, following industry lobbying concerns about the challenges of compliance. Reuters and other sources highlight that this package aims to simplify digital regulation enforcement in general, facilitating data use for AI training under the legitimate interest legal basis but drawing criticism from privacy advocates concerned about dilution of privacy rights and enhanced power for Big Tech firms.

In summary, while the Digital Omnibus promises to reduce cookie consent banner fatigue and streamline some aspects of compliance, it also introduces new complexities and potential risks for user privacy and marketing practices. Rather than eliminating consent, the reforms signify an evolution toward browser-based centralisation of consent management, an expanded role for legitimate interest, and a redefinition of sensitive data categories. For digital marketing teams, the challenge will be staying agile as legislative and technology changes unfold, balancing compliance with the need for effective data-driven marketing.
