El Reino Infantil
Scaling predictable reach for the world's largest Spanish-language kids' channel, inside the strictest advertising rules on YouTube.
The challenge
El Reino Infantil operates at extraordinary scale: a flagship Spanish channel with 65M+ subscribers and a multilingual network of 250M+ subscribers across eleven languages. The problem was not how to get more views, but how to scale predictably and sustainably when children’s advertising rules intentionally limit what can be done. Made-for-kids content disables personalized ads, remarketing and tracking pixels; in the YouTube Kids app ads are not even clickable. On top of that, as a publisher, every incremental view had to be grown in a way that protected monetization health (RPM) rather than diluting it.
What we did
Designed the activation as a repeatable reach system rather than a one-off campaign, across Spanish-speaking Latin America, U.S. Hispanic audiences and Spain during 2024 and 2025. Every flight started with a Reach Planner forecast. Because personalization was off the table, targeting was built on market-by-market geo strategy, language logic and content adjacency where family co-viewing drives repeat sessions. We mixed formats deliberately (Bumpers, Skippable and Non-Skippable In-Stream, In-Feed, Shorts and connected TV surfaces) using Google Ads reach products and DV360 line items, with frequency caps and target-frequency buys to expand unique reach instead of saturating the same households. Creative followed Google’s ABCD framework, compliance was embedded in QA, and Looker reporting connected reach growth to monetization resilience.
Results
The program met the agreed unique reach and average frequency objectives across every priority market, flight after flight, while holding cost-efficiency controls and full policy eligibility. During the activation window the flagship channel grew from 62M+ subscribers (February 2024) to 67.6M (January 2025), and the brand’s online safety series built on its best-known characters reached 24M views and 300+ hours of viewing time in Latin America within six months before expanding into English and Portuguese. The methodology is now the operating model for the brand’s launches and evergreen catalog growth.
