A Shopify ecommerce brand spending $45K per month on Google Shopping was bleeding budget due to three structural problems: Performance Max cannibalizing brand search, Smart Shopping bidding that ignored product margins, and silent feed quality failures suppressing high-value SKUs. After a three-week rebuild addressing feed corrections, PMax brand exclusions, campaign segmentation, and conversion value rules, the account recovered approximately 60% of its lost ROAS within 60 days. The case study breaks down each problem, the exact fix, and why structural ownership matters more than bid management.
