As consumers become more aware of how their personal information is collected and used, regulators are introducing new privacy requirements designed to give individuals greater control over their data.
These developments are changing how businesses approach audience targeting, lead generation, data collection, and campaign measurement.
For digital marketers, the implications extend beyond updating privacy policies or adding consent banners; privacy regulations are influencing the technologies, partnerships, and strategies that support consumer acquisition.
For performance marketers in particular, these changes create new challenges around data quality, lead transparency, and the ability to connect marketing activity with measurable business outcomes.
Understanding these shifts is essential to building acquisition strategies that remain effective as consumer expectations and regulatory requirements evolve.
A Changing Privacy Regulatory Landscape
The United States has seen a steady expansion of consumer privacy legislation, primarily at the state level. While there is still no comprehensive federal consumer privacy law, states are establishing their own requirements governing how businesses collect, process, and share personal information.
As of September 2026, 23 states had enacted comprehensive consumer privacy laws, according to the International Association of Privacy Professionals (IAPP). Although the specific requirements vary, many establish consumer rights to access, correct, and delete personal information, as well as opt out of targeted advertising and the sale or sharing of personal data.
Recent developments illustrate how these requirements are evolving. For example, California’s updated privacy regulations, which took effect in January 2026, introduced additional requirements involving data protection assessments, cybersecurity audits, and automated decision-making technologies.
Enforcement is also becoming more prominent. In January 2025, the Federal Trade Commission (FTC) finalized an order prohibiting data broker Mobilewalla from selling sensitive location data after allegations that it collected and sold information without adequately verifying consumer consent. More recently, a January 2026 FTC order involving General Motors and OnStar addressed allegations that consumer geolocation and driving behavior data had been collected and shared without adequate disclosure and consent.
These developments demonstrate the increasing scrutiny surrounding consumer data practices throughout the advertising ecosystem. For marketers, they reinforce the importance of understanding where data originates, how it is used, and whether consumers have been given appropriate transparency and control.
How Privacy Regulations Have Changed (& Are Still Changing) Digital Marketing
Privacy regulations are influencing several established digital marketing practices, requiring businesses to reconsider how they identify audiences, personalize advertising, and measure campaign performance.
Trend 1: A Shift Toward First-Party Data
Restrictions on certain types of third-party data collection and sharing are encouraging marketers to place greater emphasis on first-party data. Information collected directly through a company’s website, customer interactions, purchases, and inquiries can provide valuable insights into consumer interests and behavior.
This shift also places greater importance on transparency. Consumers need to understand why information is being collected and how it will be used, particularly when their information may be shared with other businesses.
According to the IAB and PwC’s 2024 Internet Advertising Revenue Report, the advertising industry is increasingly exploring first-party data, contextual advertising, and data collaboration tools in response to signal loss and privacy-related changes.
Trend 2: Changes to Audience Targeting and Personalization
Reduced access to certain consumer identifiers and third-party data sources can make it more difficult to build detailed audience profiles or reach consumers based on their browsing activity.
Retargeting and behavioral advertising may also become more limited depending on applicable consent requirements and the data involved. As a result, marketers are exploring alternative approaches, including contextual advertising, which uses the content or environment a consumer is engaging with to determine ad relevance.
Personalization will remain important, but businesses must be more intentional about how they use consumer information to create relevant experiences.
Trend 3: Greater Complexity in Measurement and Attribution
Privacy restrictions and reduced access to individual-level tracking can create gaps in conversion measurement. When marketers have less visibility into the consumer journey, connecting an initial advertising interaction with a downstream purchase or inquiry becomes more challenging.
Traditional attribution models that depend heavily on cookies, device identifiers, or cross-site tracking may provide an incomplete picture of campaign performance, which makes it increasingly important for marketers to evaluate performance using multiple sources of information rather than relying on a single tracking method.
What Privacy Regulations Mean for Performance Marketers
While these developments affect the broader digital advertising industry, they have unique implications for performance marketers. Businesses that depend on measurable consumer actions, lead generation, and conversion-based acquisition models must reconsider how they collect information, evaluate opportunities, and demonstrate results.
Lead Generation Requires Greater Transparency and Accountability
Lead generation often involves multiple businesses handling consumer information at different stages of the acquisition process. A consumer may submit an inquiry through a publisher’s website, have their information processed by a lead generation partner, and ultimately be connected with an agency or advertiser.
Each step introduces questions about how the information was collected, what the consumer agreed to, and which parties are authorized to use it.
This is why transparency throughout the lead generation process is so important.
Advertisers need to understand where their leads originate, how consumer information is obtained, and whether the intended use aligns with the disclosures and permissions provided to the consumer.
Marketing partners should be able to demonstrate their data collection practices, explain how information moves between parties, and provide appropriate documentation of consent where required.
Data Quality Becomes More Important Than Data Quantity
As access to certain third-party data sources becomes more restricted, marketers need to make better use of the information they can appropriately collect.
This creates an opportunity to move toward more intentional audience development and stronger consumer qualification. First-party insights, contextual signals, and direct consumer engagement can help identify individuals with genuine interest in a product or service.
For performance marketers, this means placing greater emphasis on relevance and intent rather than simply increasing the volume of consumer data available for targeting.
Better qualification can also improve campaign efficiency. When businesses have a clearer understanding of consumer needs and purchase intent, they can reduce wasted advertising spend, improve the consumer experience, and direct resources toward opportunities with stronger conversion potential.
Measurement Must Extend Beyond Traditional Attribution
When traditional tracking methods provide less visibility into the consumer journey, performance marketers need to look more closely at what happens after the initial interaction.
Clicks, impressions, and form submissions still provide useful information, but they don’t necessarily demonstrate the business value of an acquisition campaign. Downstream metrics such as qualified leads, connected calls, completed applications, sales, and revenue provide a more complete understanding of performance.
This also makes conversion feedback between advertisers and their marketing partners increasingly valuable. Sharing appropriate downstream performance data allows partners to identify which sources, campaigns, and consumer interactions are producing meaningful results.
Ultimately, performance measurement should connect marketing activity with actual business outcomes, even as the methods used to establish that connection evolve.
Marketing Partnerships Require Stronger Compliance Standards
Performance marketing frequently involves a network of advertisers, publishers, agencies, lead generators, and technology providers. Each participant may have a different role in collecting, processing, or accessing consumer information.
As privacy requirements become more complex, advertisers need greater confidence in the practices of the partners supporting their acquisition strategies.
Advertisers and their partners benefit from shared visibility into campaign sources, lead performance, and downstream conversion outcomes. These insights help both parties identify potential issues, improve campaign quality, and maintain accountability.
Strong partnerships require a shared understanding of both performance expectations and the practices used to achieve them.
How Performance Marketers Can Adapt
Privacy regulations will continue to evolve, making flexibility an important part of any long-term acquisition strategy. To stay ahead of compliance concerns, marketers can incorporate responsible data practices into their everyday operations.
Several priorities can help businesses adapt, including:
- Prioritizing first-party data
- Making transparency part of the consumer experience
- Evaluating marketing partners carefully and choose ones you can trust
- Investing in better measurement
The Future of Performance Marketing Depends on Trust
We’ve been saying this for years: the performance marketing ecosystem needs to come down to trust.
Privacy regulations are changing the expectations surrounding how businesses acquire, manage, and use consumer information. For performance marketers, these changes create new considerations across the entire acquisition process, from audience development and lead generation to conversion measurement and partner relationships.
Businesses that prioritize transparency, responsible data practices, and reliable measurement will be better positioned to adapt.
