WPP Media’s Mark Stephenson, SVP of solutions development, shares an innovative solution for helping marketers maximize their impact on YouTube. By strategically infusing AI into channel curation and creative versioning, his team has delivered significant gains in brand lift and cost efficiency.
With consumer attention constantly shifting, brands can’t afford to move slowly. Marketers face the persistent challenge of keeping pace with consumers and finding ways to effectively engage them at every turn. Today’s fragmented media landscape further complicates this, demanding strategic content curation and precise, platform-specific creative versioning — at scale and speed.
Working collaboratively with Google, we’re finding new ways to make this possible. Through a powerful combination of proprietary and Google technology, we’re enabling faster campaign planning and more efficient, high-volume creative versioning. It’s a collaboration that is helping brands move at the world’s speed and capitalize on every opportunity to drive stronger performance.
AI-powered impact: The dual engine of YouTube 5K
AI’s ability to simplify the complex and speed up processes is central to our approach. Leveraging AI-powered operations has proved to be the ultimate unlock for YouTube, where brands can amplify their storytelling with the precision and timing that the platform’s unique environment rewards.
The value of rapid content creation is realized when you can identify the most resonant placements just as fast.
One way we are capturing this opportunity is through YouTube 5K (YT5K), our proprietary media solution developed in partnership with Google. Enabled by Gemini models, YT5K fundamentally transforms planning and creative versioning workflows, strengthening and automating critical campaign phases.
By combining YT5K’s channel curation and fast production capabilities, we empower marketers to capitalize on the power of AI for stronger, faster results. This dual-engine approach seamlessly complements and amplifies our teams’ capabilities, delivering superior client performance.
Finding the right audience in hours, not days
The value of rapid content creation is fully realized only when you can identify the most resonant placements just as fast. It’s equally important to find the specific YouTube environments and experiences in which the brand’s message will have the most impact.
For WPP Media clients, YT5K automates and enhances the heavy lifting of this process, using an AI-driven system to dynamically curate an inventory of over 5,000 channels. This allows our teams to move beyond traditional manual selection and instantly access intelligent scale via content that perfectly mirrors their campaign’s unique strategic goals.
According to our internal data, by using AI to score YouTube channels for how well they align with a brand’s objectives, we have turned what is typically a three-day planning process into a task that takes just 7.5 hours — a 10X leap in planning speed.
While the efficiency gains are impressive, the true value lies in the quality of outcomes. This deep analysis maximizes confidence that ads are appearing in the best spots to drive performance. For advertisers, this achieves intelligent scale by ensuring every ad reaches the right people in environments that strengthen the brand.
Creating the perfect ad for every screen
YouTube offers a unique opportunity to connect with audiences across multiple formats, from immersive long-form content to snackable, mobile-first viewing. To help brands fully capture this reach, YT5K uses AI to identify critical narrative beats and automatically create cutdowns from longer assets. Twenty seconds is the best for CTV viewing, where the majority of this inventory is viewed.
We’ve achieved a 93% reduction in production timelines by shifting the heavy lifting to AI, while maintaining human oversight.
This isn’t just a technical shift. It’s a powerful partnership between machine precision and human intuition. While AI accelerates variation, our teams provide the essential guidance to ensure brand consistency and strategic alignment. Furthermore, every asset is scored against YouTube’s ABCD creative best practices to ensure performance from the first frame.
Our internal data reveals that we’ve achieved a 93% reduction in production timelines by shifting the heavy lifting to AI, while maintaining strict human oversight for key nuance. This turns three weeks of manual editing into a single day of work. As a result, advertisers can secure the strongest performing inventory with assets engineered for maximum brand impact.
Real-world impact: Proving the performance
The early results of YT5K are tangible. In a recent campaign for Subway (U.K.), we applied automated channel curation, and the impact was immediate: a 15% increase in brand lift.
This performance was paired with significant cost efficiency. The campaign achieved a cost per lifted user of just £0.20, outperforming other formats but also complementing them, showing that when you buy YT5K alongside other YouTube formats, overall performance is increased. These results prove that when we use AI to get the “maths” right, the “magic” of the creative performs even better.
A new standard for brands
With YT5K, we have bridged the gap between efficiency and excellence. This evolution automates complex operational aspects of media planning, empowering our teams to strategically optimize YouTube performance and maximize growth for clients.
And we’re not stopping there. To truly supercharge this evolution, we’re integrating YT5K’s capabilities directly into WPP Open, our pioneering agentic marketing platform. This will empower our teams to activate insights seamlessly within a unified planning and execution environment, dramatically scaling performance and creating even greater impact on YouTube.
YT5K is exclusively available to WPP Media Solutions clients. Currently live in the U.K., the solution is being rolled out globally throughout 2026.
