A user under 18 visits your site, adds something to their cart, and leaves without buying. Under the old system, that’s exactly the kind of person a retargeting campaign exists to bring back.
Not anymore. As of the August 26 settlement, that user simply can’t be retargeted at all.
Meta agreed to pay up to 18 billion dollars and overhaul how it treats teen accounts, settling claims from most U.S. states that it designed its platforms to encourage compulsive use among minors. Buried inside the headline screen-time changes is a detail that matters far more to advertisers than the two-hour daily cap: Teen Targeting Restrictions now completely disable retargeting and custom audience functionality for anyone under 18.
What Actually Changed for Advertisers
Most coverage of this settlement focuses on the two-hour combined daily limit across Facebook and Instagram, the overnight lockout, and parental controls. Those changes matter for user experience, but they don’t directly touch how campaigns are built.
The Teen Targeting Restrictions do. Meta has completely disabled all retargeting and custom audience functionality for users under 18, spanning five distinct types: website custom audiences, app custom audiences, customer list custom audiences, engagement custom audiences, and video view custom audiences. If a teen interacts with your brand in any of these ways, that interaction can no longer be used to build a retargeting audience around them.
Lookalike audiences are affected too. Any lookalike built from a seed audience now automatically excludes minors, even if your original seed list wasn’t intentionally built around teen users. Removed targeting options extend further, covering interest signals and lookalikes sourced from teen seed data specifically.
Why This Matters More Than the Screen-Time Cap
The two-hour limit reduces how much time teens spend on the platform, which indirectly affects reach and impression volume over time. Teen Targeting Restrictions do something more immediate and structural. They remove an entire category of campaign mechanics for this audience, regardless of how much time they still spend on the platform within that two-hour window.
This distinction matters for how you diagnose a sudden performance shift. A slow decline in teen-audience impressions over the coming months likely traces back to reduced time-on-platform. A sudden inability to retarget cart-abandoners or site visitors under 18 traces directly back to these targeting restrictions, and it’s already active now, not phasing in gradually the way the screen-time cap is.
Industry sources expect a slow, delayed softening in reach and relevance for teen-targeted campaigns over the next 12 to 18 months, faster if other platforms like TikTok, Snap, or YouTube adopt similar restrictions under the broader settlement framework. The custom audience restrictions, by contrast, are a hard cutoff already in effect, not a gradual softening.

Who This Actually Affects
If your business doesn’t intentionally target users under 18, this may look irrelevant at first glance. It often isn’t. Any brand with a broad age range in its actual customer base, not just its intended target audience, likely has some teen users mixed into existing custom audiences without having built those audiences specifically around that age group.
This matters most for categories with naturally mixed-age audiences: fashion, gaming, entertainment, certain food and beverage brands, and any product with genuine appeal across a wide age range. If your website or app custom audiences include any teen traffic, Teen Targeting Restrictions are already quietly reducing that audience’s size and retargeting eligibility, whether or not teens were ever your primary focus.
How to Check If This Is Affecting Your Campaigns
Review your custom audience sizes for any noticeable drop coinciding with late August, particularly for website, app, and engagement-based audiences tied to broad-appeal products. A sudden, otherwise unexplained size reduction is a reasonable signal that teen exclusion is part of what’s happening.
Check lookalike audience performance specifically if your original seed audiences weren’t deliberately age-restricted. Since lookalikes now automatically exclude minors from their source data, a lookalike that previously performed one way may behave differently now that its underlying seed composition has shifted.
Audit whether any of your funnels rely on retargeting younger users specifically, even unintentionally. A cart-abandonment flow, an engagement retargeting sequence, or a video-view follow-up campaign will simply have a smaller eligible pool going forward if any meaningful share of that traffic was ever coming from users under 18.
Adjusting Your Strategy Around This
Shift more weight toward broad, non-custom-audience prospecting for products with genuinely mixed-age appeal, since retargeting mechanics that used to recapture younger visitors are no longer available for that segment specifically.
Build first-touch conversion paths that don’t rely as heavily on a second retargeting touch for products likely to attract younger buyers. If a meaningful share of your traffic skews younger, strengthening initial conversion rate matters more now that the retargeting safety net for that segment is gone.
Revisit lookalike audience performance periodically over the coming months rather than assuming past performance patterns still hold. A lookalike audience’s behavior can shift gradually as its excluded-minor composition changes the underlying seed pool it’s built from.
Common Mistakes to Avoid
Assuming this only affects brands that intentionally target teens is the most common misread of Teen Targeting Restrictions. Any broad-appeal product with mixed-age traffic can be affected without ever having built a campaign around younger users specifically.
Confusing the two-hour screen-time cap with the custom audience restrictions leads to misdiagnosing the timeline. The screen-time effect will show up gradually. The targeting restrictions are already active now.
Ignoring a sudden custom audience size drop without checking age-related causes risks chasing the wrong fix, adjusting creative or bidding, when the actual cause is a structural targeting change outside your control.
Conclusion
The two-hour daily limit dominated the headlines around Meta’s settlement, but Teen Targeting Restrictions are the change advertisers actually need to build around right now. Five custom audience types, website, app, customer list, engagement, and video view, are completely disabled for users under 18, and lookalike audiences now automatically exclude minors from their seed data as well.
The practical move today is simple. Check your custom audience sizes for any unexplained drop tied to late August, review whether any of your funnels quietly relied on retargeting younger users, and start building first-touch conversion strength for any product with genuinely mixed-age appeal.
FAQs
1. Which custom audience types are affected by the new Teen Targeting Restrictions?
Website, app, customer list, engagement, and video view custom audiences are all completely disabled for users under 18, and lookalike audiences automatically exclude minors from their seed data.
2. Does this only affect brands that intentionally target teens?
No. Any brand with broad-appeal products and mixed-age traffic can be affected, even if teen users were never an intentional part of the targeting strategy.
3. Is this the same as the two-hour daily screen-time limit?
No. The screen-time limit affects overall usage gradually. Teen Targeting Restrictions are a structural change to custom audience and retargeting mechanics that’s already active now.
4. How can I tell if my campaigns are affected by this change?
Check custom audience sizes for an unexplained drop around late August, particularly for broad-appeal products, and review whether any retargeting funnels relied on younger user segments.
