Frequently asked questions
about Google Shopping
What does a Google Shopping agency do?
A Google Shopping agency manages product feed in Merchant Center and Shopping and Performance Max campaigns for ecommerce. As Google Partner and Product Hero CSS Partner, at Growzz we run Shopping accounts focused on real margin, not gross turnover.
What is CSS Partner and why does it matter?
CSS (Comparison Shopping Service) Partners are intermediaries authorized by Google that charge less commission than direct Google Shopping. For European advertisers this translates to up to 20% lower CPC with the same positioning. We work with Product Hero, one of the leading CSS Partners in Europe.
How much does Google Shopping cost?
Google Shopping has no fixed fee: you pay CPC per click. The investment that makes sense depends on margin, catalog, average product price and target markets. We don't work with preset minimums — we study your case and propose how much to invest in each format. With CSS Partner you also reduce the cost of each CPC.
What's the difference between Shopping and Performance Max?
Classic Shopping gives you granular control per product and campaign. Performance Max is more automated: a single campaign activates Shopping, Display, YouTube and Discover with machine learning. PMax typically performs better with large catalogs and enough conversion volume; classic Shopping gives more control with small or niche catalogs.
Do you optimize the product feed?
Yes, it's the first lever. We rewrite titles with real keywords (50% of Shopping performance depends on the title), normalize attributes, optimize images, configure custom labels for segmentation, and resolve disapprovals.
