Measurement
Brand suitability
Brand suitability is choosing which content is appropriate for a specific brand's ads, based on its own values and risk tolerance, above the universal floor set by brand safety.
Once the universally unacceptable content is excluded (brand safety), plenty of content remains that is fine for some brands and not others. A horror film trailer suits a thriller streaming service but not a nursery brand; a news story about a plane crash is fine for a soap brand but not an airline.
Brand suitability lets advertisers set their own tolerance by category and risk tier. Frameworks such as the one GARM published define content categories (for example, violence, adult content, alcohol, debated social issues) with low, medium and high risk levels, and verification and contextual vendors classify pages and videos against them.
Good suitability settings protect reputation without throwing away reach. Blanket exclusion of "news" or "sensitive" topics can cut large, valuable audiences and starve journalism. Suitability decisions are strategic, so marketers should review them with evidence, such as performance by category, rather than rely only on default settings. Suitability is also an input to contextual targeting, because the same classification can be used to find good placements, not just avoid bad ones.
Think of it like this
Suitability is like choosing which parties your band plays: nothing illegal, of course, but a heavy-metal band and a string quartet will still pick very different gigs.
An example
An Indian airline sets high-risk exclusions for aviation accident news and violence, but allows mainstream news and sports; its reach increases 18% compared with its previous blanket block on all news sites.
