What does TAG Brand Safety Certified require, and what does the seal prove?
Part of Brand suitability
The short answer
TAG Brand Safety Certified is a voluntary seal from the Trustworthy Accountability Group for companies whose ad operations in a named market follow its Brand Safety Certified Guidelines. An independent auditor validates the company's policies, lists and partner contracts. The seal covers a company's process, not single sites, so buyers confirm it on the TAG Registry.
Key takeaways
- The seal is awarded to a legal entity for named countries or regions, and it requires independent validation and annual recertification.
- Version 5.0 of the guidelines, dated July 2026, sets different duties for buyers, sellers, intermediaries, verification services and anti-piracy providers.
- Certified buyers and intermediaries must apply misplacement avoidance tools to 100% of the monetizable transactions they handle.
- The guidelines leave the definition of suitable content to the advertiser, so a certified partner still needs the brand's written criteria.
- Buyers confirm the seal and its markets on the TAG Registry and can report suspected non-compliance with written evidence.
What is TAG Brand Safety Certified, and what problem does it target?
The Trustworthy Accountability Group, known as TAG, runs four programs listed on its certifications page (opens in a new tab): Certified Against Fraud, Certified Against Malvertising, Brand Safety Certified and Certified For Transparency. The Brand Safety Certified page (opens in a new tab) states a mission "to significantly reduce the risk of the misplacement of advertising," meaning ads placed beside content an advertiser would not choose, pirated material included.
Definition
- Brand Safety Certified seal
- A TAG seal for a company shown, through independent validation, to follow the Brand Safety Certified Guidelines in the markets TAG names. It certifies controls for avoiding ad misplacement, not the content of one website.
The program dates from September 2020, when the Brand Safety Certified Guidelines (opens in a new tab) first merged the JICWEBS Digital Trading Standards Guidelines with TAG's Inventory Quality Guidelines. Version 2.0 in July 2021 folded in TAG's piracy program, which is why anti-piracy duties sit beside brand safety duties. The current text is version 5.0, released in July 2026. Fraud is a separate seal, covered in our guide to TAG Certified Against Fraud.
Which companies can hold the Brand Safety Certified seal?
Only TAG members can apply. A company first becomes "TAG Registered" and enrolls in Verified by TAG (opens in a new tab), a background check after which TAG issues "a TAG ID (a unique 16-character identifier)." Its membership must include the Brand Safety Certified program. Applicants then fall into five covered party types, and a company playing several roles applies under each one.
| Covered party | Who it is, in the guidelines' terms | Where it sits in a North American buy |
|---|---|---|
| Direct Buyer | An advertiser that owns the ads, or an agency directly representing it | Brand and media agency |
| Direct Seller | A publisher providing content to an audience, or an agent directly representing it | News site or sales house |
| Intermediary | A company operating technology for buying digital inventory, as indirect seller or buyer | Exchange, SSP, DSP or network |
| Content Verification Service | Classifies context and alerts or blocks ads, without transacting inventory | Suitability classification provider |
| Anti-Piracy Service Provider | Helps limit ads on properties linked to copyright infringement or counterfeits | Piracy detection provider |
Scope is set per market. Section 2.3 allows certification by country, by region such as North America, or globally, and any use of the seal "must identify the geographic markets to which it applies." TAG certifies at the entity level, so the seal belongs to a legal company, not to one product line.
What must a company do to earn and keep the seal?
Brand Safety Certified has one method. Section 2.4 says companies "must apply to achieve the Brand Safety Certified Seal through independent validation": an approved auditor with a digital media specialty examines the company, and its compliance officer and a business executive sign attestations. The auditor reviews training records, internal controls, complaint handling and quarterly review testing, and for verification and anti-piracy providers tests whether disclosed capabilities work.
Keeping the seal is a yearly cycle. The company names a TAG Compliance Officer independent from sales and marketing, runs quarterly internal reviews, and applies for recertification by January 31. TAG says it gives the outcome by March 1.
Which duties fall on buyers, sellers and verification services?
Section 4 of the guidelines splits the work by role. Buyers carry the duty to say what is acceptable; intermediaries must carry that out; sellers must disclose how they police their own properties; verification services must disclose what they can and cannot classify. The table summarizes the duties that touch a media plan.
| Duty | Direct Buyer | Direct Seller | Intermediary | Verification service |
|---|---|---|---|---|
| Define criteria for where ads may run and pass them to partners (Principle 3) | Yes | No | Must honor the buyer's criteria (Principle 4) | No |
| Apply misplacement avoidance tools to 100% of monetizable transactions (4.6) | Yes | Discloses its own monitoring policies instead | Yes | No |
| Document and review inclusion and exclusion lists quarterly (4.11) | Yes | Named in the 4.1 table and section 2.6.e, not in section 4.11 | Yes | No |
| Publish sellers.json or buyers.json with a TAG-ID identifier (4.14) | No | No | Yes | No |
| Disclose where classification was not possible, and why (4.15) | No | No | No | Yes |
Version 5.0 added three duties: direct sellers must accept and investigate reports of illegal content (4.12); intermediaries that run search or AI crawlers and monetize those services with ads must disclose crawler purposes and honor robots.txt (4.13); and intermediaries must carry their TAG-ID in sellers.json or buyers.json (4.14), the files explained in our sellers.json and buyers.json guides.
What does the Brand Safety Certified seal not guarantee?
The seal attests that controls exist and were validated; it does not rule on content. Principle 3 makes the direct buyer define "the criteria to be met in order for digital advertising to be presented," so the definition of a suitable page stays with the brand. Buyers may meet the avoidance duty with "Independently validated Content Verification services or Brand Safety Inclusion/Exclusion lists," so two certified buyers can use different methods.
| Question a buyer asks | Does the seal answer it? | Where the answer lives |
|---|---|---|
| Does this partner have documented misplacement controls in my market? | Yes, for the entity and markets on the Registry | The TAG Registry entry and the seal's named markets |
| Is this particular site suitable for my brand? | No | A page level suitability review against the brand's own criteria |
| Is the site built mainly to resell ad impressions? | No | Ad layout, paid traffic and content quality checks |
| Is the traffic free of invalid traffic? | No; that is a different TAG seal | Certified Against Fraud status and invalid traffic reports |
Appendix B shows how the program defines a floor. It lists the 11 sensitive topics from IAB Tech Lab Content Taxonomy version 2.2 and a 12 item Brand Safety Floor that adds misinformation. The World Federation of Advertisers discontinued GARM in August 2024. Its Brand Safety Floor and Suitability Framework is a legacy reference, not an operating standard or certification. Our brand safety floor guide compares the lists.
How can a buyer confirm that a partner holds the seal?
TAG calls its Registry (opens in a new tab) "the official database for the global TAG Community," showing partners with "their TAG membership status and any TAG certifications they hold." A logo in a pitch deck is a claim; the Registry entry is the record.
Five steps to confirm a Brand Safety Certified claim
- Search the Registry by legal name. Match the company that signs the insertion order, not a product name.
- Read which seals are listed. Brand Safety Certified, Certified Against Fraud and Verified by TAG are separate entries.
- Check the markets. Confirm the United States, Canada or North America appears for a North American buy.
- Match the role. Ask which covered party types the partner certified under, since each role carries its own duties.
- Look for the TAG-ID in its files. A certified intermediary carries it in the identifiers object of its sellers.json or buyers.json file.
What does a seal review look like on a real brief?
Fictional example. The brand and partners are unnamed and invented; no results or performance figures are implied.
A cat food maker checks its partners before a Montana launch
An unnamed pet food maker is launching a dry cat food line with display ads in Montana, covering Billings, Missoula and Bozeman, in English. Its agency proposes an exchange, a buying platform and a verification provider, and each pitch deck shows a TAG logo.
The agency searches the TAG Registry for each legal entity. The exchange holds Brand Safety Certified for the United States. The buying platform holds Certified Against Fraud but not Brand Safety Certified, so the agency records that gap and asks how the platform applies avoidance lists. The verification provider holds the brand safety seal under the content verification role.
The brand manager then writes the criteria down: veterinary advice, pet care and local lifestyle content wanted, animal cruelty cases and graphic injury content avoided. The agency sends them to both transacting partners in writing, the step Principle 3 places on the buyer.
- Registry search by legal entity for three partners.
- Market check: United States listed on the exchange's seal.
- Gap recorded for the buying platform.
- Criteria written by the brand and sent in writing.
How can a buyer put its suitability criteria into a site list before buying?
The guidelines make the advertiser's criteria the starting point for certified partners. A site list built against those criteria gives the partners something concrete to honor.
What happens when a certified company breaks the guidelines?
TAG's complaints page (opens in a new tab) asks anyone raising a concern for "written documentation demonstrating the relevant incident(s) of non-compliance." Under TAG's Due Process for Allegations of Non-Compliance and Appeal (opens in a new tab), version 3.0 of May 2024, staff may investigate on a reasonable basis, using information from any source.
The company can file an opposition brief and appeal a staff decision to a review panel drawn from the ANA, the 4A's and the IAB. A first finding of non-compliance removes the certification for six months and TAG names the company publicly; a second removes it for two years; a third for five years. Buyers who report should keep evidence specific: dates, placements and the requirement at issue.
Frequently asked questions
Can a company self-attest to Brand Safety Certified?
No, under version 5.0 of the guidelines. Section 2.4 requires independent validation by an approved auditing company with a digital media audit specialty, plus binding attestations from the company's compliance officer and a business executive.
Does a publisher with the seal guarantee its pages are suitable for my brand?
No. A certified direct seller discloses its policies for monitoring ad misplacement, attests that it owns or licenses its content, and accepts reports of illegal content. Whether an article fits a brand depends on the criteria the advertiser defines.
Why does the program include anti-piracy rules?
TAG merged its piracy program into Brand Safety Certified in version 2.0, July 2021. Certified buyers, sellers and intermediaries must filter pirate mobile apps and pirate domains; using TAG's own pirate lists is allowed but does not, in and of itself, meet the requirement.
Does the seal cover connected TV and apps?
The program's mission covers digital media of all types, and Appendix A defines mobile as mobile web and in-app content. The seal still applies only to the markets and roles TAG certified, so ask which operations the validation examined.
