What is a CSS

What most advertisers don't realize about Google Shopping

A Comparison Shopping Service (CSS) is the infrastructure through which your Shopping ads enter Google’s auction in Europe.

Every advertiser already uses one.

Most just use Google’s default CSS without realizing alternatives exist.

Switching CSS does not change:

Your campaigns
Your data
Your tracking
Your feed
Your learning phase

It only changes how efficiently your budget competes.

Simple explanation

How Google Shopping actually works

Think about Google Shopping like this:

Google Shopping
the marketplace

Where customers discover products.

Merchant Center
your product database

Where your feed lives.

Google Ads
your budget

What you invest to generate sales.

CSS
your auction entry structure

How efficiently your bids compete.

Most agencies optimize campaigns.

Very few optimize infrastructure.

That’s where hidden performance gains usually exist.

Comparison

Google CSS vs Thyssen CSS

Google CSS:

Thyssen CSS:

Actual results depend on account structure and competition.

Where most brands actually lose performance

Most brands focus on:

  • Increasing budgets
  • Testing creatives
  • Changing bids

But performance is often lost in:

  • Increasing budgets
  • Testing creatives
  • Changing bids

Performance is rarely just about spending more.

Most of the time it’s about fixing structural inefficiencies.

CSS is one of them.

Benefits

Up to 25% CPC efficiency improvement

Performance-focused CSS support

Most CSS providers only provide infrastructure.

We focus on performance.

We help identify:

  • Feed opportunities
  • Structure improvements

Execution does.

We don't treat performance like marketing

We treat it like infrastructure.

We focus on the details most agencies ignore:

  • Feed optimization
  • Tracking accuracy
  • Campaign structure
  • Auction positioning
  • Data interpretation
  • Execution discipline


Many times we complicate simple things.

Our approach is usually the opposite:

Nothing changes. Except efficiency.

Switching CSS is a backend change.
Your campaigns continue exactly the same:

No rebuild

No data loss

No learning reset

No tracking impact

No feed changes

No downtime

Your campaigns stay the same.

Your setup gets more efficient.
