Problem

Yeogi Eottae wanted its summer advertising to produce brand searches as well as broad exposure in a competitive travel market.

Approach

The travel platform combined YouTube placements with AI-powered Video Reach and Video View campaigns. Machine learning adjusted delivery across 4 audience segments rather than relying on separately allocated segment budgets. The wider campaign also used celebrity creative and premium placements.

Results

31%increase in brand-search query volume for the overall campaign, according to GoogleVendor case study[1]

Takeaway

The search increase covered the combined campaign. Google did not isolate the contribution of machine-learning delivery from creative content or other placements.
