Using a single click in the GrowthAds Platform, Wavemaker activated cookieless inventory, extending their campaigns to reach previously untapped audiences. To measure the effectiveness of this approach, they utilized the Cookieless Breakdown Report, which provided key campaign metrics like spend, impressions, uniques, clicks, and conversions in both cookied and cookieless environments. Additionally, they implemented an A/B test to compare the performance of a traditional campaign using third-party cookies with a campaign fully delivered to cookieless audiences.
