🛠 3 Tactics to Use Today

1. Build a new customer pipeline with YouTube creator integrated ads: Following the Bombas example, structure partnerships with YouTube creators using an "integration" method (content integration, not simple sponsorship). Set "net-new reach" (not overlapping with existing potential customers) as the campaign KPI and prioritize creators with low audience overlap by comparing their subscriber data with your own customer data.

2. Set "Brand Guardrails" for Meta Advantage+ AI automation immediately: If you are running Meta Advantage+, check your brand safety category exclusion settings in your ad account today. Register a weekly review checkpoint in your team calendar to manually review AI-generated creative variants, and explicitly upload brand color, font, and messaging guidelines into the "Brand Identity" section of your ad account.

3. Respond to Google Search AI mode: Immediately strengthen product feeds and structured data: As Google Shopping's AI mode expands, fill in missing attributes (color, material, size, etc.) in your Merchant Center product feed today. Apply Schema.org Product markup to your product landing pages to increase your chances of appearing in AI Overviews and Virtual Try-On features. Specifically, checking image quality (at least 800×800px, white background) has a direct impact on AI shopping exposure.

Comparative analysis content between open-source MMM tools like Meta’s Robyn and Google Meridian is also expected to emerge.
