Machine Learning to Estimate Age and Apply Built-In Protections
Google has announced a new set of protections for minors across its platforms, powered by machine learning tools designed to estimate user age. As explained in Google’s official blog, these measures will help prevent underage users from seeing content and ads meant for adults.
The company is starting by testing its “age assurance” feature in the U.S., where it will analyze behavior such as search queries and YouTube activity to determine if a user is likely under 18. If a user is flagged as a minor, Google will automatically turn off ad personalization and block access to what it calls age-sensitive ad categories. These include ads for alcohol, gambling, weight loss, and high-fat or high-sugar foods and beverages.
Expanded Protections Across Google Products
Google is applying these protections across a range of services:
- YouTube: Minors will be enrolled in YouTube’s Digital Wellbeing program. This includes features like content limitations, reduced repeat video exposure, and screen break reminders.
- Google Maps: Timeline tracking will be disabled to protect location privacy.
- Google Play: Apps restricted to adult audiences will be blocked from access.
In addition to these steps, Google is enforcing stricter controls in Search by filtering out mature or explicit results for users under 18. These filters apply automatically and cannot be disabled.
Strengthening Privacy and Data Protections
Google says it will soon roll out new default settings for Family Link, its parental supervision tool. Parents will be able to manage their child’s web and app activity settings more easily. The system will also prompt teens to verify their privacy settings and encourage them to take an active role in managing their own data.
New prompts will also guide teens through choosing privacy controls on their devices and accounts, making the process more transparent and understandable.
Why This Matters
These changes are part of Google’s broader strategy to meet new regulations and evolving expectations around teen safety online. The company has acknowledged the need for stronger safeguards, especially in light of recent criticism over how ads are delivered to younger users.
As reported by Adweek, this rollout follows internal concerns and earlier claims that some advertisers were attempting to bypass protections and target teens on YouTube. Google’s move also aligns with similar efforts by other tech platforms, such as Meta, to introduce stronger age-related controls.
What Comes Next
The age assurance system is still in its early testing phase, but Google says it plans to expand availability based on user feedback and performance. These updates are meant to build a more trustworthy environment for young people across Google’s services.
