Google this week clarified how Demand Gen and Discovery campaigns interact with its restricted targeting rules for personalized advertising, confirming that both campaign types use advertiser-curated audiences by default and may be restricted from serving when those campaigns promote products or services in sensitive interest categories.

What changed on June 3, 2026

The update, posted on June 3, 2026, did not introduce a new policy. Instead, according to Google's Advertising Policies Help Center, the company updated the "Restricted targeting in Personalized advertising" article to include "clarifying information around Demand Gen and Discovery campaigns and potential serving implications for targeting products and services that fall within sensitive interest categories."

The distinction matters. Google framed the June 3 update explicitly as a clarification, not a rule change. Yet for advertisers running Demand Gen or Discovery campaigns in health, finance, alcohol, gambling, and other regulated sectors, the published note is the clearest official statement Google has made about how these campaign types sit within its existing policy architecture.

The clarification lands at a moment when Demand Gen has become a central campaign type in Google's advertising stack. The format absorbed YouTube Video Action campaigns by April 2025, has seen a series of rapid feature additions, and now operates across YouTube (including Shorts), Google Discover, Gmail, and associated display inventory.

The two-category system behind personalized advertising

To understand what the June 3 clarification means operationally, it helps to look at how Google's personalized advertising policy divides audience targeting tools.

According to the company's policy documentation, there are two broad categories of audiences: advertiser-curated audiences and predefined Google audiences.

Advertiser-curated audiences include Customer Match lists, data segments (previously known as remarketing lists), audience expansion, lookalike segments, and custom segments. These are tools where the advertiser has contributed data or shaped the audience definition themselves. Because they may inadvertently contain sensitive user signals - such as health conditions, financial hardship, or religious beliefs - Google prohibits their use when the advertiser is promoting products or services within any of the 21 listed sensitive interest categories.

Predefined Google audiences work differently. According to Google's policy, "predefined Google audiences are expressly configured without sensitive user signals," which is why all advertisers are allowed to use them even when promoting within sensitive interest categories. This group covers in-market segments, affinity audiences, demographics, detailed demographics, life events, location targeting, and - following a December 2025 policy change - custom segments for Display campaigns.

The core rule, spelled out in the policy documentation, is straightforward: "advertisers promoting products and services that fall within sensitive interest categories are unable to use advertiser-curated audiences."

Why Demand Gen and Discovery are specifically affected

The June 3 note introduced one sentence that has significant practical weight. According to Google's updated documentation: "Discovery and Demand Gen campaigns use advertiser-curated audiences by default and may be restricted from serving if targeting products and services that fall within sensitive interest categories."

That default behavior is what differentiates these two campaign types from, say, standard Search or standard Display. An advertiser setting up a Demand Gen campaign does not begin from a neutral audience state - the campaign is structured around the same advertiser-curated tools that are prohibited when sensitive categories apply. If the campaign's creative, landing page, or product falls within a sensitive interest category and the targeting hasn't been reconfigured to rely solely on predefined Google audiences, the campaign may not serve at all.

Discovery campaigns - the predecessor format that Demand Gen was built upon - operate under the same default and face the same restriction.

This is not a trivial nuance. A healthcare brand, an alcohol advertiser, or a company running clinical trial recruitment campaigns running Demand Gen with default audience settings could find campaigns silently restricted. The policy does not describe this as a warning before suspension. It describes it as a serving implication - the campaign may simply not deliver.

PPC Land has tracked the rapid evolution of Demand Gen targeting controls over the past year, including the February 2026 change that converted lookalike segments from hard targeting constraints into audience suggestions starting March 2026. The June 3 clarification adds another layer to that picture: campaign-level defaults now carry compliance consequences for regulated advertisers.

The full list of sensitive interest categories

Google's policy documentation lists 21 sensitive interest categories. The restrictions apply across all of them, covering a range of topics that span health and identity to finance and content. The categories are: abuse and trauma, alcohol, birth control, clinical trial recruitment, commission of a crime, gambling, health, imposing negativity, location-based gambling, marginalized groups, negative financial status, political affiliation, political content, race and ethnicity, relationship hardships, religious beliefs, restricted drug terms, sexual content, sexual orientation, trade union membership, and transgender identification.

The breadth of this list means the policy affects many more advertisers than those in obviously regulated sectors. A company running a Demand Gen campaign for a financial counseling service, a mental health platform, a fertility product, or a dating application would each fall within one or more of these categories and would need to review their audience targeting accordingly.

Access to opportunities: a separate set of restrictions

Beyond sensitive interest categories, Google's policy also applies a distinct framework for what it calls "access to opportunities" categories. These apply specifically in the United States and Canada, and cover housing, employment, and consumer finance advertising.

For ads in these three categories, the restrictions go further than simply prohibiting advertiser-curated audiences. According to the policy documentation, advertisers in the US and Canada cannot use demographic targeting on the basis of gender, age, parental status, or marital status. ZIP code targeting is also prohibited for these categories, though radius-based geographic targeting - requiring a minimum 1 km radius around a given location - remains permitted. For Canadian advertisers, forward sortation area (FSA) targeting, which uses the first three characters of a postal code, is acceptable.

The rationale the policy gives for these restrictions is equitable access. These rules "are designed to help ensure equitable access to opportunities in Housing, Employment, and Consumer finance in the United States and Canada." Google first moved toward restricting financial ad targeting on demographic lines with a policy change announced in November 2023 and effective February 28, 2024.

Data collection rules that sit alongside targeting restrictions

The personalized advertising policy also sets out data collection requirements that are independent of but complementary to the targeting restrictions. According to the policy documentation, advertisers are not permitted to run ads that collect personally identifiable information - such as email addresses, telephone numbers, or credit card numbers - within the ad itself unless using a Google-provided format designed for that purpose.

Advertisers also cannot use personally identifiable information in combination with anonymous or pseudonymous data such as cookies, data segments, or data feeds. Sharing PII with Google through data segment tags or product data feeds is prohibited. And sending Google precise location information requires prior user consent.

A footnote in the policy documentation addresses one additional restriction with particular relevance to youth-facing campaigns. According to the policy: "users under the age of 18 are not eligible for personalized advertising of any kind, including serving based on predefined Google audiences." This means the protections for under-18 users operate at a level above both the sensitive category restrictions and the predefined audience permissions - even the normally unrestricted predefined Google audiences cannot be used to deliver personalized ads to minors.

Custom segments with sensitive content

A fourth-footnote qualification in the policy documentation addresses a specific edge case for custom segments. According to Google's documentation: "custom segment audiences using sensitive creative assets or pointing to sensitive landing pages will only serve with Display campaigns to non-sensitive audiences or contextually. All other campaigns using custom segment audiences with sensitive creative assets or landing pages will not be eligible to serve."

This creates a tiered outcome depending on campaign type. A custom segment tied to a health-related landing page can still serve on Display - but only to non-sensitive audiences or via contextual targeting. On Demand Gen, YouTube, or other campaign types, that same custom segment would not serve at all. The implication for advertisers using product-focused custom segments is that the sensitivity classification of the landing page or creative, not just the audience itself, determines eligibility.

Three paths for advertisers with flagged campaigns

When a campaign is flagged under the personalized advertising policy, Google's documentation sets out three options.

The first is to edit ad targeting - removing advertiser-curated audiences from targeting settings at the campaign, ad group, and asset group levels. For Demand Gen and Discovery campaigns that use such audiences by default, this is the most direct resolution.

The second option is to edit or remove the content that causes the policy flag - either from the site or app, or from the ads themselves. This involves navigating to the ad within the Campaigns menu, editing the relevant asset, and saving to trigger an automatic re-review.

The third option is to appeal the policy decision. According to the documentation, if a review determines that ads are compliant, they can run again. Google notes that if violations are not resolved, removing the ad is preferable to allowing repeated violations, since repeated infractions can result in account suspension.

This three-path framework is not new, but it now explicitly applies to Demand Gen and Discovery campaigns. The policy update covering social casino games in November 2024 illustrates how Google has historically used the sensitive interest category framework as a lever it can adjust - removing specific subcategories from restrictions when commercial and legal circumstances shift. The June 3 clarification does the reverse: it makes the default-audience implications for two major campaign types explicit in writing.

Context: a sustained narrowing of targeting controls

The June 3 update fits a pattern of tightening that has moved through Google's advertising products across the past 18 months. Lookalike segments in Demand Gen shifted from hard targeting constraints to audience suggestions in March 2026. A $5 minimum daily budget floor for Demand Gen campaigns took effect April 1, 2026. Customer Match uploads moved to the Data Manager API with a hard deadline that passed in early 2026. Google Ads cut granular reporting data access to a 37-month window starting June 2026.

The common thread is that advertiser-level controls over audience data - who to target, how to segment, how long to retain, how narrowly to constrain reach - are being narrowed or centralized into Google's own systems. The June 3 clarification, framed as a documentation update, is part of that same structural drift. Advertisers who relied on Demand Gen's flexible audience tools as a point of differentiation from Search campaigns now have explicit policy language confirming those tools are off the table in a wide range of verticals.

For the marketing community, the question is less whether these restrictions are justified and more whether they are understood and operationally reflected in campaign setups. Google's AI-mediated campaign types have made it easier to launch campaigns quickly - but the same ease of setup that reduces friction at launch can obscure the policy requirements that govern what the campaign is allowed to do once it runs.

Summary

Who: Google, affecting advertisers running Demand Gen and Discovery campaigns in any of 21 sensitive interest categories, as well as advertisers in housing, employment, and consumer finance sectors in the United States and Canada.

What: Google updated its "Restricted targeting in Personalized advertising" Help Center article on June 3, 2026, to explicitly state that Demand Gen and Discovery campaigns use advertiser-curated audiences by default and may be restricted from serving when promoting products or services that fall within sensitive interest categories. The update also consolidates rules covering data collection, demographic restrictions for access-to-opportunity categories, and remediation paths for flagged campaigns.

When: The clarification was posted on June 3, 2026. The underlying policy rules it clarifies have been in place for some time, though their explicit application to Demand Gen and Discovery campaigns was not previously documented in this form.

Where: The update appears in Google's Advertising Policies Help Center, specifically in the "Restricted targeting in Personalized advertising" article. The restrictions apply globally, with the access-to-opportunities category restrictions limited to the United States and Canada.

Why: Google's stated rationale for sensitive interest category restrictions is to prevent advertiser-curated audience tools - which may contain sensitive user signals - from being used to target users on the basis of protected characteristics or personal circumstances. The clarification appears intended to address ambiguity about how Demand Gen and Discovery campaigns fit within this framework, given that both campaign types default to advertiser-curated audience configurations.
