Catching product-feed problems before they cost a month

The challenge

For an e-commerce retailer running Shopping campaigns, the product feed silently decides how much of the catalogue can compete. Products get disapproved or demoted, prices drift out of competitiveness, and by the time it shows up in revenue reporting, weeks of spend have underperformed.

What we did

We built a monitoring service on the Google Merchant Center reporting APIs that runs on a daily schedule: tracking product approval status, demotions, price competitiveness against the market, best-seller coverage and performance trends. Every run is stored in a local history database so changes are detected against yesterday — not against memory — and meaningful shifts trigger an email alert the same day.

The outcome

Feed regressions that previously surfaced in month-end reviews now arrive as same-day alerts with the affected products attached. Daily monitoring gives the team earlier visibility of disapprovals, demotions and price-competitiveness shifts, and pricing decisions are informed by a current view of where the catalogue stands against the market — rather than one reconstructed weeks later.
