The challenge

One of the world’s most recognizable cosmetic brands wanted to increase brand awareness and reach their ambitious marketing goals. The brand is best known for its advertising campaigns that challenge stereotypes and celebrate a modern vision of femininity. The client’s campaign requirements included strict brand safety guidelines, ambitious cost goals, and, of course, gorgeous creatives. To build a successful campaign in a competitive field like the beauty industry, RTB House had to achieve high reach, engagement, and visibility.


The solution

To meet this challenge, RTB House worked closely with the client team and Starcom to build a solid media plan and the first batch of creatives. This included building a detailed understanding of the target customer base. While launching the awareness video campaign, RTB House integrated its Deep Learning-powered ad buying engine with a new billing model—cost per completed view (CPCV)—to maximize engagement while minimizing cost. CPCV is a particularly interesting billing model as it ensured that the client only paid for fully engaged views, and therefore got the most out of their campaign.


The result

RTB House implemented branding campaigns with a novel approach that exceeded expectations. While planning the campaigns, RTB House worked with the client to set market benchmarks for viewability and cost. The video and display campaigns achieved much higher results than the original benchmarks, despite challenging setup and a rigorous brand safety policy from the client.

Across the campaigns, RTB House reached 3.14 million unique users and reduced CPCV by 10%.

In the video campaigns, the ads reached an impressive 84% viewability—4.25% above the 80% goal that was set. Video completion rates also rose to 66% for 15-second videos.

As for the display ads, the campaign achieved 88.2% viewability—35.7% higher than the initial 65% goal for the campaign.
