Misalignment between ad creative and landing pages is a persistent leak: promising one thing in an ad and delivering another on the page costs trust, inflates noise, and kills experiments. In this 15‑minute panel Gustavo and Michelle introduce the 'Creative Contract'—a compact, human+machine readable metadata schema (intent tag, offer type, urgency bucket, primary CTA) and a simple collaboration workflow that binds creative assets to landing selection rules. Gustavo walks low‑dev implementation options (ad-platform creative metadata, UTM+intent tags, CMS rule-maps, and a client-side fallback mapper) and explains measurement wiring that preserves privacy and avoids PII. Michelle turns the contract into brand-safe tone buckets, CTA templates, and a 3‑question review checklist so creatives and page owners ship aligned copy. The episode closes with a 72‑hour pilot plan (contract template, mapping rules, experiment variants, monitoring and rollback), sample JSON contract, and a subscribe CTA to grab the mapping checklist—let's decode!
