🎯 Campaigns & Brand Moves to Watch

Bombas — Creator Partnership Expansion (90% Net-New Customer Win)

• Overview: Sock-and-apparel brand Bombas systematically scaled creator partnerships and converted 90% of their customer base into net-new acquisitions—meaning almost no overlap with prior customers.
• The creative play: Not just "send product to influencers." Instead: analyze creator audience composition, map it against existing customer cohorts, and funnel budget to partners whose subscribers have zero overlap. Pure incremental reach.
• The result & buzz: That 90% figure is getting industry attention because it proves creator marketing is moving from retargeting dependency to actual new-demand creation.

Expedia Group — Meridian-Powered Measurement Shift ("Goodbye, Defensive Metrics")

• Overview: Expedia Group moved beyond click-and-impression vanity metrics. Using Google Meridian MMM, they now measure brand and performance campaigns' actual revenue contribution in one unified model.
• The creative play: Solved the "every channel claims credit" nightmare. MMM lets you isolate each channel's real lift. CFO gets proof, not promises.
• The result & buzz: A major travel platform adopting open-source MMM is already triggering industry-wide measurement rethinks.

Instacart — CMO Rewires Retail Marketing with AI ("Retail Never Stands Still")

• Overview: Think with Google spotlighted Instacart's CMO using AI to turbocharge retail marketing. Real-time shopping behavior and search data feed live ad optimization. Retail media meets AI precision.
• The creative play: Retail media networks + AI = ad accuracy soars and both retailer and brand ROI prove it. Dual-win.
• The result & buzz: Retail media is graduating from "digital ad channel" to "AI-powered performance platform."

📊 Benchmarks & Data Points

• Bombas creator partnerships: 90% of converted customers are net-new, with no prior overlap. Rare quantified proof that creator marketing drives genuine incremental demand.

• HubSpot 2026 State of Marketing: Survey of 1,500+ marketers globally identified AI adoption, authentic brand POV, and Loop Marketing as the three-pillar growth model.

• KPI shift for high-performing teams (HubSpot, January 2026): Winning marketing teams now track Loop-based (cyclical) performance metrics, not single-campaign KPIs. Long-term customer journey cumulative performance beats snapshot metrics.

• YouTube positioning 2026: Think with Google officially repositions YouTube as a full-funnel performance channel, not a single touch point. Attention → action closure happens in-platform.

🛠 Three Tactics to Run Today

1. Reframe creator partnerships as core customer acquisition, not just awareness: Pick creators the Bombas way—use YouTube Analytics' audience overlap data to find partners whose subscribers have zero overlap with your existing customer base. Measure the "incremental reach %" for each creator. Allocate budget to the highest-incremental partners first.

2. Layer Google Meridian MMM on top of your current attribution: Grab the Meridian GitHub repo. Feed 6–12 months of spend data and watch it spit out channel-by-channel revenue contribution. Use it to brief your CFO with hard proof, not attributed clicks. It's the "single source of truth" Expedia built.

3. Audit your campaigns for agent-readiness before May 20: Before Agentic Ads drop, check three things: ① feed completeness (do all your products have rich attributes?), ② Performance Max creative diversity (multiple headlines, images, descriptions?), ③ conversion goal setup (is the signal clean?). Fix these now and you'll move fastest when the new features land.

🔭 Next Week to Watch

• Google Marketing Live (May 20): Agentic Ads reveal, AI Max updates, new measurement tools likely. This rewrites Google's ad ecosystem.
• Google I/O (May 20 week): AI agent and Gemini announcements will likely tie into ad platform features. Marketers should monitor the dev sessions too.
• HubSpot Loop Marketing follow-up: Expect detailed execution frameworks and performance dashboards. Applicable across B2B and B2C.

✅ Action Items for You

• Calendar lock: Google Marketing Live livestream, May 20. Pre-audit your campaigns for agent-powered search readiness.
• Creator audit: Pull your creator partner list. Use YouTube audience overlap data to identify three+ partners with highest net-new reach potential.
• Meridian pilot: Visit Google Meridian GitHub. Run a proof-of-concept MMM with your last quarter's spend. Goal: channel attribution deck for your CFO by month-end.
