Three years into our performance partnership with Helloprint, the product feed was the bottleneck. Inconsistent titles. Poorly structured attributes. Feed logic that didn't support strategy. Shopping and Performance Max scaled on budget, not on data quality. We rebuilt the feed inside Channable. Structured rules cleaned and enriched product data. Titles and attributes were aligned with search intent. Feeds were architected to support continuous testing and international expansion across DE, IT, and US without breaking the core setup. The shift drove Shopping and Performance Max performance budget alone couldn't deliver. Campaigns now scale on product quality. International rollouts run without losing focus on the core countries. And as Google's bidding logic evolves (NCA, Performance Max updates, query matching) the Channable layer keeps the feed moving with it. Three years in, Channable is still the connective tissue between Helloprint's catalog and every channel they sell on. That is how a partnership scales instead of stalls.
