We know the feeling
The truth about day-to-day Google Merchant Center
GMC and Google Ads are two separate interfaces but deeply linked — moving between them costs you time every day.
Feed errors surface too late — products disapproved for days with no alert, and budget spent on nothing.
Performance by category and product requires exports — no way to analyse quickly without data wrangling.
No quick way to see which products drive the most Shopping revenue without digging through complex tables.
GMC diagnostics are highly technical — feed errors, missing attributes, incorrect GTINs — and hard to interpret quickly.
Performance Max with no visibility into which products actually get pushed — you invest without knowing what's working.

"Which 10 products have the best Shopping ROAS this month?"
Top 10 products by Shopping ROAS — June 2026: (1) Pro X12 Running Shoes: 8.4 ROAS (€4,200 rev.). (2) Waterproof Trail Jacket: 7.9 ROAS. (3) 30L Backpack: 7.2 ROAS. … (10) Merino Socks: 5.8 ROAS. These 10 products account for 67% of your Shopping revenue on just 23% of the budget. Recommendation: raise the budget on the top three by 40%.
"Which GMC feed errors are hitting my campaigns this week?"
3 critical errors detected — week of 23 June: (1) 47 products disapproved for "non-compliant image" — €8,200 of potential revenue blocked. (2) Missing GTIN on 23 products — reduced feed quality, higher CPCs. (3) Prices out of sync on 12 products — risk of further disapprovals. Top priorities: fix the images and add the GTINs to recover the 47 disapproved products urgently.
"Compare Standard Shopping vs Performance Max last month"
June 2026 comparison — Standard Shopping: 5.8 ROAS, €0.42 CPC, 1,840 conversions · Performance Max: 7.2 ROAS, €0.61 CPC, 2,290 conversions. PMax performs better (+24% ROAS, +24% conversions) but with a 45% higher CPC. Standard Shopping still wins on brand terms (9.1 ROAS vs 7.4). Recommendation: leave PMax on the general catalogue and keep Standard Shopping for brand queries.
