PPC Case Study: How We Achieved 12:1 ROAS on Google Shopping

AutoParts Direct were stuck at a 2.8:1 ROAS with a $15K monthly budget. Here is the exact process we used to quadruple their return in 90 days.

The Audit

Three root problems emerged immediately: product titles were generic (not using search term data), the campaign had no custom label structure (treating a $0.50 spark plug the same as a $400 exhaust), and there was zero audience layering.

Feed Optimisation

We rewrote 3,000 product titles using 6 months of search term reports, creating a keyword-informed title formula: Brand + Product Type + Key Attribute + Fitment. This alone improved CTR by 40%.
