Children's advertising on connected TV is one of the most tightly regulated categories in programmatic media, and one of the most frequently misconfigured. The Children's Online Privacy Protection Act (COPPA), the FTC's implementing regulations, and platform-specific children's content policies create a compliance framework that applies to publishers distributing kids content, advertisers appearing in kids content, and the ad technology infrastructure that serves ads in those environments. A publisher who enables behavioral targeting on a kids CTV app is in violation of COPPA regardless of whether they know it. An advertiser whose campaign appears in kids content through programmatic open auction may be violating their own brand policy without any visibility into where their ads are running. The ad server handling that transaction is part of the compliance chain. This guide covers what COPPA requires in the CTV context, how publishers and advertisers should configure their campaigns and inventory, and how the LtvAdx ad server enforces compliance in kids-classified environments.
What COPPA requires and who it applies to
COPPA applies to operators of websites and online services — including CTV apps — that are directed to children under 13, or that have actual knowledge that they are collecting personal information from children under 13. The Act prohibits collecting, using, or disclosing personal information from children without verifiable parental consent. In the advertising context, "personal information" includes persistent identifiers — device advertising IDs, IP addresses, cookies, device fingerprints — used for behavioral advertising or tracking purposes. This prohibition effectively bars behavioral advertising on COPPA-covered services.
A CTV app is "directed to children" under COPPA if it meets any of a list of factors that the FTC evaluates: the subject matter (animated characters, child-friendly themes), the visual content (bright colors, simplified graphics associated with children's media), the use of animated characters or child celebrities, the music, the age of models depicted, and the nature of advertising on the app. An app does not need to explicitly market itself as a children's service to be covered by COPPA — an app featuring cartoon characters and educational content for young viewers is likely directed to children even if the app store listing says "for all ages."
The FTC has enforced COPPA against major digital platforms, CTV app operators, and ad technology companies with substantial penalties — enforcement actions in the video streaming space have produced fines in the hundreds of millions of dollars. CTV publishers who have not conducted a COPPA applicability analysis for their kids content apps should treat this as a material compliance risk, not a theoretical concern.
What advertising is permitted in kids CTV content
COPPA does not prohibit advertising in children's content — it prohibits behavioral advertising based on persistent identifier tracking. The advertising that is permitted in COPPA-covered environments is contextual advertising: ads selected based on the content being watched, the app category, or other non-personal signals that do not require persistent tracking of the viewer. A toy brand advertising on a CTV animation channel is permissible if the ad is selected based on the kids content context, not based on the viewing history, device profile, or behavioral segment of the household.
In OpenRTB terms, a COPPA-compliant bid request from a kids CTV app must not include: device advertising IDs (Roku RIDA, Amazon AFAI, etc.), IP address as a targeting signal (beyond the level needed for geographic content delivery), persistent household identifiers, or user segment data. The bid request should signal COPPA applicability through theregs.coppa: 1 flag, which tells receiving DSPs to not use behavioral data in their bidding decisions for this impression. The OpenRTB CTV best practices guide covers the COPPA signal field in the OpenRTB specification.
The LtvAdx ad server's kids mode — applied to all publisher inventory classified as children's content — enforces COPPA compliance automatically: device advertising IDs are suppressed from outbound bid requests, behavioral targeting is disabled, HouseholdID activation is turned off, and the COPPA flag is set in all bid requests originating from kids-classified inventory. Publishers do not need to manually configure COPPA compliance for each bid request — the classification drives the enforcement.
FTC advertising content guidelines for children
Beyond COPPA's privacy requirements, the FTC imposes content standards on advertising in children's media through its general unfair and deceptive advertising authority. Advertising to children must be clearly distinguishable from programming content — children's developmental limitations in distinguishing advertising from entertainment create a heightened deception standard. Ad-integrated content (host-selling, character merchandising, product placement) is subject to additional scrutiny. Endorsements and testimonials in children's advertising must reflect the honest views of the endorser and not depict product performance that exceeds what the product actually delivers.
In CTV terms, these content standards mean that sponsored content or branded entertainment in kids CTV must include clear disclosure language, cannot feature characters from the content itself promoting products without disclosure, and cannot use production techniques (soundtrack, visual style, characters) that make the ad indistinguishable from content. Advertisers running in kids content through CTV programmatic should review their creative against FTC guidelines before campaign launch, not just after an adjacency issue surfaces.
Advertiser category restrictions in kids content
Certain advertiser categories are categorically prohibited from advertising in children's programming on both regulatory and brand safety grounds. Alcohol, tobacco, gambling, adult entertainment, firearms, and pharmaceutical products requiring physician involvement are restricted from children's content advertising by industry self-regulatory codes (CARU — Children's Advertising Review Unit) and are blocked by most major CTV publishers and platforms in their kids content inventory.
Beyond prohibited categories, there are categories that are legally permitted but carry audience appropriateness concerns in kids content contexts: fast food and high-sugar food and beverage advertising has faced significant regulatory pressure globally; violent or action-based toy and video game advertising may be restricted to specific programming contexts; financial products and services have no place in under-13 content. Publishers operating kids CTV apps should define their category inclusion list for kids inventory explicitly — specifying which categories are permitted, not just which are prohibited — to prevent unexpected adjacency from categories that slipped through a prohibition-only list.
The LtvAdx publisher portal allows publishers to configure category restriction lists at the channel and app level. For kids-classified inventory, the platform's default configuration applies a broad prohibition list aligned with CARU guidelines. Publishers who want to permit additional categories (age-appropriate educational products, children's media and entertainment brands) can configure inclusion exceptions within the compliance framework.
Publisher classification: mixed-audience apps and classification responsibility
One of the most common compliance mistakes in CTV kids advertising is the mixed-audience classification problem: a publisher whose app serves both kids content and general audience content may classify the entire app as general audience to preserve behavioral targeting revenue, while serving significant volumes of content that a COPPA analysis would classify as directed to children. This is a high-risk classification decision that the FTC has specifically addressed in enforcement guidance.
For mixed-audience apps, COPPA regulations (as amended in 2013) allow publishers to treat "known children" differently from general users — applying COPPA protections only to the portion of the service where children are the primary audience. In CTV practice, this means classifying specific content categories or channel sections within a mixed-audience app as kids mode and applying COPPA-compliant ad serving only to those sections. LtvAdx supports session-level kids mode activation through the SSAI ad decision API — publishers can pass a kids content flag at the session or asset level, triggering COPPA-compliant serving for that specific content regardless of the overall app classification.
Coppa and the SSAI delivery path
The SSAI delivery path creates a specific COPPA compliance consideration that client-side VAST does not: in SSAI, the stitcher makes the ad call rather than the player, and device signals are passed from the player session initialization to the stitcher at session start. If the player passes device advertising IDs in the session initialization for a kids content session, and the stitcher includes those IDs in outbound bid requests, the SSAI path becomes the vehicle for COPPA violation even if the publisher intended to suppress those signals.
The LtvAdx SSAI engine handles this by evaluating the kids content flag at session initialization time: when a kids session is detected (either by content classification or explicit flag), the stitcher suppresses device advertising ID passthrough in all outbound bid requests for that session, regardless of what device signals the player sent during initialization. This ensures COPPA-compliant ad serving even when the player SDK has not been separately configured to suppress device IDs for kids sessions.
Practical compliance checklist for publishers
Publishers operating CTV apps that include any children's content should work through the following before activating programmatic advertising. First, conduct a COPPA applicability analysis: is any portion of the app directed to children under 13 under the FTC's multi-factor test? Second, classify all content accurately at the section or asset level, not just at the app level. Third, configure kids mode at the appropriate level in the LtvAdx publisher portal — app, channel, or session — matching the classification granularity. Fourth, verify that outbound bid requests from kids-classified inventory include the regs.coppa: 1 flag and exclude device advertising IDs. Fifth, configure category restriction lists to block prohibited advertiser categories from kids inventory. Sixth, review creative acceptance policies for kids inventory with the team responsible for direct sales to ensure no prohibited creative enters through the IO channel.
For advertisers, the practical COPPA checklist is simpler: ensure your DSP is configured to honor regs.coppa: 1 flags and not use behavioral data for COPPA-flagged impressions; review your targeting setup to confirm kids content IAB categories are excluded from campaigns with behavioral audience segments; and confirm your creative meets FTC content standards for children's advertising before running in any inventory that may include kids content.
