04 / Comparison Shopping Service
Klarna CSS
Switch your Google Shopping CPCs to Klarna CSS and cut click costs by up to 20%. Same ads, same positions, lower bids.
When you run Google Shopping, your product ads are served through a Comparison Shopping Service, or CSS. By default that is Google Shopping itself. Since the EU antitrust ruling, Google has had to let rival CSS providers compete on equal terms, and ads served through an alternative provider get a discount on the auction price. Klarna is one of the strongest providers going.
What a CSS actually changes
A CSS is the layer your Shopping ads run through, not a new campaign and not a new platform. Switch the layer and the bid you pay falls, while the ad, its position and the landing page stay exactly as they were. Move your account to Klarna CSS and your Shopping and Performance Max clicks can cost up to 20% less.
Why Klarna CSS
Klarna is a premium CSS provider, not a budget reseller skimming margin off your account. We move your Google Merchant Center across as a clean technical switch that never touches your live campaigns. Same ads, same positions, lower cost per click, and more budget left to scale what already works.
How the switch works
It is a Merchant Center change, done in a handful of steps and reversible whenever you want. Your campaigns keep running throughout, and most accounts see their CPCs drop within days of going live. No downtime, no rebuild, no risk to the performance you have already earned.
Who it is for
Any ecommerce business running Google Shopping or Performance Max. Klarna CSS works as a standalone service whether or not you use RTN for Google Ads management or feed optimisation. Want to see what the saving looks like on your own account? The Free Audit is the quickest way to find out.
Common questions
- Does switching to Klarna CSS affect my live campaigns?
- No. It is a Merchant Center change, not a campaign change. Your ads keep running throughout, with the same positions and the same landing pages. The only thing that changes is the cost per click.
- How much can Klarna CSS save on my CPCs?
- Ads served through an alternative Comparison Shopping Service get a discount on the Shopping auction price. In practice that works out at up to around 20% lower CPCs on Shopping and Performance Max, which leaves more budget to scale what already works.
- Is the switch reversible?
- Yes. You can move your Merchant Center back at any time. Nothing is locked in.
- Do I have to use RTN for Google Ads to get Klarna CSS?
- No. Klarna CSS works as a standalone service whether or not we manage your Google Ads.
- How long does it take to go live?
- It is a handful of steps in Merchant Center. Most accounts are live within days, and the lower CPCs show up shortly after.
