Guest Post: "Behavioural Ads Are Bad for Kids"

Ariel Fox Johnson, of Common Sense Media, writes that it is "common sense" to keep kids' data off-limits and to change the business model that uses behavioural advertising. Ms. Johnson will participate in an event with our office on June 8th - for more details, see our recent blog post.


We have all learned that "free" comes at a price - often, to our privacy. For years, the costs of apps and services have been subsidized by their users' information, feeding an ad-supported model that tracks and profiles all of us, including children and teens. We are categorized and labeled ("Working-class Mom," "The Awkward Years - High School Students," "Rich Kids of America"), and then manipulated and microtargeted with the ads and content that companies believe relevant.

Indeed, researchers recently discovered Facebook would let them target teens labeled as "interested in gambling" with ads featuring poker chips and dice. Other equally disturbing ads could be purchased to target teens interested in alcohol, smoking, or extreme weight loss.

Big tech companies have convinced advertisers and marketers that the more targeted the ads are, the better, but this business model's underlying profitability for most companies is questionable. More traditional "contextual" ads, which are displayed based on a website or app's content and not on who is visiting it, may be nearly as profitable and much less controversial.

The behavioral ad model has underappreciated costs, especially for kids. In Common Sense’s recent explainer, we examine the practice of behaviourally targeted advertising, the harms it poses for young people, and what policymakers and companies can do to improve the landscape.

Behaviourally targeted ads are now standard fare for online platforms, and they have become very big business. But the truth is, behaviourally targeted ads are bad for kids.

  • Kids do not want targeted ads. Most kids and parents are uncomfortable with the idea that their data is being used for targeted advertising.

  • Kids do understand how their information is collected, analyzed, and used by commercial actors, and they are largely defenseless against such targeting techniques.

  • Behavioural profiling is particularly problematic for kids because it happens at a unique time of development -- when both their brains and identities are developing and forming. Historically, this is precisely when society has encouraged children to explore new things and not worry about making mistakes.

Common Sense believes that children and teens should not be tracked and profiled online, or subject to behavioural ads based on their personal information or online activity. And we are supportive of global efforts to achieve this goal, undertaken by regulators, legislators, and companies themselves. We believe everyone can work together, for example by:

Given growing agreement that the status quo is not working for kids and families, we look forward to new movement on this issue.
