What is CSS?
A Comparison Shopping Service is a platform that lets consumers compare products and prices. Google Shopping is one CSS, and independent CSS partners can also submit Shopping ads in Europe.
How CSS partners work
When you use a CSS partner, product data is submitted through that partner while you keep control of your Shopping activity.
A good CSS setup should improve efficiency without forcing a campaign rebuild.
Choosing a partner
Look for commercial clarity, support quality, setup speed, and whether the partner can help beyond the CSS switch itself.
