The Future of Meta Advertising Is Here: Key Insights from Meta’s Performance Summit
On May 13-14, Brandon Turner attended Meta’s Performance Summit in San Jose, California, where one message was clear from the opening speaker: artificial intelligence is no longer an emerging capability at Meta; it is the foundation of how the platform operates and evolves.
Across nearly every discussion, Meta emphasized that AI is becoming the engine behind all aspects of advertising within its ecosystem. From audience targeting and placement decisions to creative interpretation and optimization, AI enhancements are increasingly embedded beneath every advertising surface. The conversation extended beyond individual tools and features and focused on a broader transformation toward intelligent systems and business AI agents capable of assisting advertisers with campaign setup, optimization, and even creative direction directly within Ads Manager.
A major theme was the increasing importance of advertiser input. Advertisers are being asked to consistently provide deeper signals around business goals, success metrics, profit considerations, conversion quality, and the reasoning behind campaign outcomes. The message was straightforward: the more meaningful context advertisers provide, the stronger and more accurate AI predictions become.
Beyond AI, measurement emerged as another core focus area. Meta strongly reinforced that traditional last-click attribution is no longer sufficient for understanding true business impact. Instead, the platform continues to invest heavily in incremental attribution (IA), emphasizing its ability to capture outcomes that traditional measurements often miss.
Meta shared compelling findings from large-scale testing. Using a seven-day click attribution model, purchase activity on the platform was found to underreport actual impact by roughly 15%. Additionally, nearly one-third of marketing impact occurred downstream through channels such as Amazon and retail partners that traditional last-click reporting struggles to capture. Particularly notable was that 64% of conversions identified through incremental attribution represented new customers.
The summit also highlighted Meta’s sharpened focus on new customer acquisition (NCA). With only approximately 5% of a brand’s total addressable audience actively in-market at any given time, optimizing solely toward existing demand limits long-term growth opportunities. Meta is continuing to invest in solutions that help advertisers intentionally identify and acquire net-new customers.
Additionally, creators emerged as a compelling theme throughout the summit. Meta presented creator content as one of the most effective inputs into its advertising ecosystem, with creator-led content producing stronger engagement and relevance signals across the platform. Partnership ads paired with Advantage+ Shopping Campaigns (ASC), user-generated content, and greater alignment between media, analytics, and creative teams were repeatedly positioned as high-performing strategies.
Why This Matters for Harmelin Media Clients and Advertisers
For Harmelin Media clients, these shifts reinforce several priorities already guiding our strategic approach:
- Better inputs create stronger outcomes: Supplying platforms with richer business context and higher-quality signals will increasingly drive performance advantages.
- Measurement must evolve: Incrementality and broader attribution frameworks will be critical for understanding true marketing impact and growth.
- New customer acquisition should remain a priority: Sustainable growth depends on expanding audiences rather than relying solely on retargeting.
- Creative and media integration matters more than ever: Creator partnerships, user-generated content, and cross-functional collaboration are becoming essential components of high-performing campaigns.
As Meta’s ecosystem continues to evolve, Harmelin Media remains focused on translating these platform changes into practical strategies that help clients maximize performance, uncover growth opportunities, and stay ahead of industry shifts.
