Brand safety and brand suitability are complementary but not interchangeable, and confusing the two is the most common reason advertisers either over-block valuable inventory or under-protect their brand. Brand safety is the universal floor of content that all advertisers should avoid, such as hate speech and illegal acts. Brand suitability is the brand-specific layer on top of that floor, where advertisers set their own thresholds for content that may be acceptable for one brand and inappropriate for another. The industry's shared structure for both is the GARM Brand Safety Floor + Suitability Framework, which defines twelve high-caution content categories and grades sensitive content within them as low, medium, or high risk.
Understanding Brand Safety and Brand Suitability
Brand safety establishes the essential baseline of protection, while brand suitability builds the customized framework that aligns ad placements with a brand's specific identity. As Viant Technology explains in its guide on the two concepts, suitability is "a highly personalized layer tuned directly to an individual brand's unique values, tone, and strategic goals," and content that is perfectly acceptable for one advertiser may be entirely inappropriate for another based on their audience and brand identity.
For instance, a pharmaceutical company might deem it suitable for its advertisements to appear with health and wellness news, whereas an automotive company would likely consider it damaging to its reputation for ads to run alongside content about car accidents. While both scenarios might be considered 'safe,' only one aligns with the specific brand's values and message, highlighting that suitability is about appropriate fit rather than merely avoiding harm. In practice, safety typically relies on exclusion lists, pre-bid filtering, and verification tools applied before and after a campaign runs, while suitability adds granular control over which adjacencies actively fit the campaign's goals.
The GARM Brand Safety Floor and Suitability Framework
The Global Alliance for Responsible Media (GARM) began work on shared language and standards for advertising and media in November 2019, according to the framework document itself. The output had three parts: a common understanding of what harmful and sensitive content is via content categories; a common understanding of where ads should not appear, expressed in a Brand Safety Floor; and a common way of delineating different risk levels for sensitive content, expressed in a Brand Suitability Framework. The combined GARM Brand Safety Floor + Suitability Framework was first published in September 2020, and in June 2021 work began to add Misinformation as an additional harmful content category.
The Brand Safety Institute, which now hosts the framework, describes it as "a set of definitions intended to ensure that the advertising industry is categorizing harmful content in a common way from organization to organization." The twelve categories that make up the Floor and Framework were identified in consultation with industry experts and NGO representatives, giving suppliers, intermediaries, service providers, and buyers a shared vocabulary for deciding what is safe and suitable in their media buying activities.
The Brand Safety Floor: Universal Avoidance
The safety floor identifies content adjacencies that are never appropriate for advertisers, regardless of brand. According to the 4As' Brand Safety Playbook, which recounts the framework's development, the industry groups that built it started from the IAB Tech Lab's Content Taxonomy and settled on a dozen commonly agreed-upon high-caution areas for content, then outlined which editorial treatments of content in those buckets constituted adjacencies that are never appropriate for advertisers.
Crucially, the floor is not absolute in every case. The same 4As account notes that the framework's authors acknowledged that, based on the treatment or delivery context of the content—such as a news story or a documentary—risky content could be appropriate to a brand and its values. That acknowledgment is precisely what opened the door to the suitability layer: context and editorial framing matter, and a documentary about extremism is not the same as extremist content.
Brand Suitability: Customizing Risk with GARM Categories
Above the floor, suitability lets each advertiser decide its own tolerance within the twelve categories. Integral Ad Science, whose measurement approach is aligned to the GARM framework, explains that suitability "takes the next step by aligning with content that's an ideal fit for a brand's values or campaign goals," with advertisers setting their own suitability thresholds and profiles. Its example: a family-focused brand may not want to appear next to content about alcohol drinking, whereas that may be a suitable placement for an alcohol brand.
Under the GARM-aligned approach, suitability is measured as content scored as low, medium, or high risk across the twelve supported content categories. This tiering is what makes suitability operational rather than aspirational: instead of a vague instruction to "avoid sensitive content," an advertiser can specify, category by category, which risk levels it will accept, monitor, or block.
Applying GARM Risk Levels: Low, Medium, High
The Brand Suitability Framework applies perceived levels of risk to the treatment of content within the dozen categories, per the 4As playbook. In other words, the risk level reflects not just the topic but how the content treats it—news reporting on a tragedy, for example, is treated differently from content glorifying it. Advertisers then map each category and risk level to an action: allow, monitor, or block.
One practical caveat: the framework's definitions have been adapted by different implementers. Triton Digital's methodology page, for instance, describes suitability models that classify content using definitions "adapted from the IAB framework." Advertisers should confirm which version of the taxonomy their partners apply, since category boundaries and risk scoring can differ between implementations.
GARM Brand Suitability Decision Framework
The matrix below shows how to translate the framework into placement rules. The content examples are illustrative, drawn from the categories and risk logic described in the GARM-aligned sources, and are not an exhaustive list for any category. The action column reflects a typical conservative-to-moderate profile; a brand with different values would shift the boundaries.
| Content category | Low risk | Medium risk | High risk | Typical action |
|---|---|---|---|---|
| Debated social issues | Neutral news reporting | Opinion or advocacy coverage | Inflammatory or one-sided attacks | Allow low; monitor medium; block high |
| Arms and ammunition | Policy or legislative news | Sport-shooting coverage | Promotion of weapons use | Allow low; monitor medium; block high |
| Tragedy and conflict | Factual news reporting | Graphic-adjacent coverage | Sensationalized or graphic imagery | Allow low; monitor medium; block high |
| Adult and explicit content | Educational or clinical context | Suggestive themes | Explicit material | Block medium and high |
| Any category at the safety floor | — | — | Hate speech, illegal acts | Block universally |
The reasoning path is straightforward: first apply the universal floor, then classify the remaining content by category and risk tier, then assign an action per tier. A family brand might block the medium tier for alcohol-related categories where an alcohol brand would allow it—the framework's structure is shared, but the thresholds are yours.
Building Your Brand's Suitability Profile
Viant recommends separating universal safety baselines from brand-specific suitability preferences and writing both down as actionable, clear standards for internal teams and media partners, supported by exclusion lists for untrustworthy domains, low-quality apps, and unsafe keywords. The Brand Safety Institute's guidance on how the framework is used extends this: marketers may apply the definitions to set brand risk and suitability standards at corporate, brand, and campaign levels, while agencies can use them to guide investment at both agency-wide and individual campaign levels.
The framework's stated goals—consistent categorization, transparency about where sensitive content is present, and clarity in exceptions for responsible speech and public interest—mean a suitability profile should be documented, not improvised. Note the boundaries of this article: it explains the GARM framework but does not provide legal advice on advertising regulations, does not review or recommend specific verification vendors or tools, and uses illustrative examples rather than exhaustive category lists.
Customizing Your Brand's Suitability Profile
Advertisers should proactively define their brand's unique suitability profile by mapping GARM content categories to specific risk levels (low, medium, high) and corresponding actions. The measurable indicator of success is a documented brand suitability policy that clearly outlines acceptable and unacceptable content adjacencies for advertising campaigns, regularly reviewed and updated. That document—shared with internal teams and media partners, and revisited as the framework's categories and platform implementations evolve—is what turns a shared industry standard into your own placement rules.
