The Haus analysis reveals that while Meta's advertising platform generally shows incrementality in driving sales, the shift towards automated campaigns like Advantage+ may not improve incremental efficiency for all brands. Data from 640 incrementality tests indicates that although Advantage+ performs well in new customer acquisition, many brands still see better returns from traditional Manual campaigns in terms of overall efficiency. The findings underline the importance of understanding individual business performance relative to Meta's automated tools.

Meta's Web & App campaigns are an underutilized feature that simplifies ad management by allowing users to set both app and web destinations at the ad level, enabling better conversion tracking and efficiency. By consolidating campaigns across platforms, marketers can achieve significant cost-per-acquisition reductions and streamline their efforts, ultimately leading to more effective advertising strategies.
