# Google CSS

> Comparison Shopping Services partner advantage — lower CPCs and incremental Shopping reach for e-commerce brands.

Google CSS (Comparison Shopping Services) is a programme that allows certified partners to serve Google Shopping ads on behalf of merchants — at a structural CPC advantage over ads served directly through Google.

As a certified Google CSS Partner, we pass this advantage directly to our e-commerce clients.

## How CSS works

<Steps>
  <Step title="CSS partner serves Shopping ads">
    Instead of your Shopping ads being served by Google Shopping directly, they are served by our CSS partner account.
  </Step>

  <Step title="Structural CPC reduction">
    Google charges CSS partners a lower base rate than direct merchants — because they do not apply the Google Shopping comparison service fee. This translates to a structural CPC reduction of approximately 15–20%.
  </Step>

  <Step title="Same placement, lower cost">
    Your ads appear in the same Shopping placements as before — same visibility, same click volume — but at a lower cost per click.
  </Step>

  <Step title="Incremental reach">
    CSS accounts can also surface ads in additional CSS-eligible placements not available to direct Google Shopping advertisers — extending reach.
  </Step>
</Steps>

## What the CPC advantage means

For an e-commerce brand spending €10,000/month on Shopping, a 15–20% CPC reduction means:

* The same budget buys 15–20% more clicks
* Or the same click volume costs 15–20% less budget
* At a 5× ROAS, that structural saving compounds significantly over 12 months
