The brand-safety challenge

Programmatic advertising moves faster than manual review

A single misplacement — an airline ad beside a plane crash story, a children’s toy ad on an adult page — can trend on social media within minutes. The solution is not blocking entire categories; it is classifying the web at a granularity that separates “Financial News > Market Analysis” from “Financial News > Fraud Reports.”

700+ categories for surgical precision

Generic classification tools offer 30–50 categories. Blocking “News” kills reach. Allowing it invites risk. Our 700+ category taxonomy lets you build inclusion and exclusion lists at a granularity that protects brand reputation without sacrificing scale. Every category maps to IAB v2 and v3 standards for industry compatibility.

102M domains — the long tail is covered

Brand-safety incidents disproportionately occur on sites that generic databases have never classified — newly registered domains, niche blogs, parked pages monetizing arbitrage traffic. Our corpus covers 102 million domains including the long tail that competitors skip. A site registered this morning already has a classification by tonight.

Real-time classification at bid-request speed

Our API responds in under 100 milliseconds — fast enough for pre-bid brand-safety checks in programmatic auctions where every millisecond counts. SSPs and DSPs integrate a single API call into their bid-evaluation pipeline. The response returns category labels, confidence scores, and quality indicators in one payload.

Protect reach, not just reputation

Overly aggressive blocking wastes budget and limits scale. Our multi-label classification assigns every applicable category to each domain, so your brand-safety logic can weigh context rather than issuing blanket bans. A health education site with medical content stays accessible; an adult site with medical keywords does not. Nuance at scale.

Capabilities

Every layer of brand-safety intelligence, from one engine

Our classification infrastructure powers every stage of the brand-safety workflow — from pre-bid URL evaluation to post-campaign adjacency auditing.

Pre-bid URL classification

Classify the page URL before your DSP submits a bid. Our sub-100ms API returns category labels, safety scores, and quality indicators so your bidder can make brand-safe decisions without adding latency to the auction.

Inclusion & exclusion lists

Build dynamic inclusion and exclusion lists using our 700+ categories. Update them automatically as new domains are classified — no manual curation, no stale lists. Export as CSV, JSON, or consume via API for real-time integration with your bidding platform.

GARM framework alignment

Our category taxonomy maps directly to GARM (Global Alliance for Responsible Media) brand suitability categories. Arms/ammunition, adult content, hate speech, terrorism, and every other GARM-defined risk area has a corresponding classification in our database.

Contextual audience enrichment

Beyond safety classification, our Cookieless Audiences platform adds demographic, interest, and purchase-intent profiles to every domain. Target safely and contextually in one data layer — no third-party cookies required.

Multi-taxonomy classification

Every domain is classified across IAB v2, IAB v3, IPTC NewsCodes, and web-filtering taxonomies simultaneously. Your brand-safety logic gets the IAB categories your buyers expect, while your compliance team gets web-filtering labels for regulatory reporting.

Offline database option

For environments where API calls are impractical — air-gapped ad servers, edge-deployed systems, or bulk pre-processing pipelines — our offline databases deliver the same classification data in CSV, JSON, or SQLite. Process millions of URLs locally with zero latency.

Scale

The classification engine behind brand-safe programmatic

Brand safety depends on the depth, freshness, and accuracy of the data behind it. Here is the scale our classification engine operates at.

How it works

From bid request to brand-safe decision in milliseconds

When your bidding system encounters a URL, it sends a single API request to our classification engine. The response returns every applicable category, a confidence score, quality indicators, and audience data — all within the timing window of a programmatic auction.

Because our engine assigns multiple labels per domain, your brand-safety logic can make nuanced decisions. A news site covering a sensitive topic carries both its news category and the specific sub-category that triggered concern — giving your policy engine the context it needs to decide rather than block blindly.

  • Sub-100ms response fits pre-bid evaluation timing
  • Multi-label classification enables nuanced policy decisions
  • Confidence scores let you set threshold-based rules
  • IAB v2 and v3 taxonomy alignment for industry compatibility
  • Quality score identifies MFA sites and arbitrage pages

Straight answers

Common brand-safety assumptions, addressed

“Blocklists are enough”

Static blocklists cannot keep pace with 300,000 new domains registered daily. A list that was comprehensive last month has blind spots today. Our classification engine processes new domains continuously, so your brand-safety coverage evolves with the web.

“Blocking news keeps us safe”

Blocking the entire “News” category eliminates access to premium, brand-safe inventory. Our 700+ categories distinguish “Business News > Market Analysis” from “Crime > Violent Crime” — protecting reputation without sacrificing the reach that news environments offer.

“Brand safety and targeting are separate systems”

They don’t have to be. Our API returns both safety classification and audience intelligence in one response. Evaluate brand safety and contextual targeting in the same pre-bid call — no second vendor, no second lookup, no additional latency.

“Our verification vendor handles this”

Verification vendors often use the same generic databases with limited category depth. Layering our 700+ category classification into your existing stack gives verification systems the underlying data quality to make better decisions — not replace them, but make them more accurate.

“MFA sites are too fast to catch”

Made-for-advertising sites are a classification problem, not a speed problem. Our quality scoring identifies MFA characteristics — thin content, excessive ad density, clickbait patterns — and flags them as a category your bidder can exclude. New MFA domains get classified as they appear in our 300K/day pipeline.

“We only need English-language coverage”

Brand-safety incidents happen in every language. Our classification engine processes content in all languages and scripts, classifying domains regardless of their primary language. Global campaigns need global coverage — not just the English-language web.
FAQ

Brand safety, asked and answered

How does your classification compare to IAS, DoubleVerify, or MOAT?
We are not a verification vendor — we are the classification engine that verification systems should be using. Our 700+ category taxonomy and 102M-domain corpus provide the underlying data quality that determines how accurate any verification decision is. Many organizations layer our classification into their existing verification stack to improve granularity and long-tail coverage.
Does the API add latency to bid requests?
Our API responds in under 100 milliseconds, which fits comfortably within the timing window of a standard OpenRTB auction. For even lower latency, our offline databases let you pre-load classifications locally and perform lookups with zero network latency. Many SSPs use a hybrid approach: offline data for known domains, API calls for newly discovered URLs.
How quickly are new domains classified?
Our pipeline processes approximately 300,000 newly registered or changed domains every day. A domain registered this morning typically has a classification by the end of the same day. API responses always reflect the latest classification. Offline database subscribers receive refreshed exports on their license schedule.
Do you support GARM categories?
Yes. Our category taxonomy maps directly to all GARM brand suitability categories. We provide a GARM mapping table that shows which of our 700+ categories correspond to each GARM risk area, so your brand-safety policies can reference GARM terminology while using our granular classification underneath.
Can I combine brand safety with contextual targeting?
Absolutely. A single API call returns both safety classification and audience intelligence from our Cookieless Audiences platform. You can evaluate brand safety and contextual targeting in one pre-bid decision — ensuring the placement is both safe and relevant without a second vendor or additional latency.
What formats do you support for offline integration?
Our offline databases are available in CSV, JSON, and SQLite formats. They range from 1 million to 102 million domains and include the same category labels, confidence scores, and quality indicators as the real-time API. Most programmatic platforms use CSV or SQLite for bulk pre-processing and API calls for real-time classification of unknown domains.
Is there a free trial?
Yes. Our Website Categorization API offers a 14-day free trial with no credit card required. You can test classification quality against your own URL inventory, validate category granularity for your brand-safety use case, and benchmark API latency before committing. Database products include free sample downloads.
How do you handle sites that change content frequently?
Our classification pipeline re-evaluates domains on a continuous cycle, with higher-traffic and higher-risk sites evaluated more frequently. When a domain’s content changes significantly, its category labels are updated accordingly. This is especially important for news sites and UGC platforms where content volatility directly impacts brand safety.
