Google Shopping and Performance Max
Product campaigns in Google Shopping, and Merchant Center at large scale.
For a modern online shop, product campaigns (Google Shopping and Performance Max) are the main source of revenue. We make the assortment earn the most from every auction, whether it holds 500 products or 500,000.

- Feedcertification, rules, supplemental feeds, disapprovals

Three costly mistakes of a large catalog.
- 1
Everything in one campaign
The algorithm puts 80% of the budget on 5% of the most popular products, often the low-margin ones, and ignores the rest of the catalog.

Thousands of valuable products get not a single impression in a month.

Merchant Center disapprovals
A missing GTIN, a wrong tax, a price mismatch, or a weak photo blocks the key assortment.
Scope
Merchant Center and Google Shopping.
Product data
Feed engineering
Primary feeds through the API, XML, CSV, Google Sheets, or a scheduled fetch.
Supplemental feeds add EAN, GTIN, labels, and promotions without waiting for the shop developers.
Feed rules rewrite titles, map google_product_category, and replace wrong attributes.
custom_label_0 to custom_label_4
Custom labels
Margin: a high margin gets an aggressive Target ROAS, a low margin a stricter profit requirement.
Price and basket: cheap accessories apart from expensive core products.
Turnover: bestsellers, a sale, new arrivals, and end of line.
Quiet products get their own sub-campaign and a low CPC, so they enter the auction at all.

Disapprovals and suspensions

Questions
My feed has more than 100,000 products and the XML file is too heavy. How do you handle that?
Compression, a split of feeds by category, or the Google Merchant API (REST). Prices and stock come down incrementally in a few seconds, without a giant XML.
How does a product campaign in Performance Max differ from the old Standard Shopping?
Performance Max adds Search, YouTube, Gmail, and the Display network on top of Shopping. It needs sharper asset-group segmentation and brand exclusions, so the budget is not burned.
