What is CSS

Comparison Shopping Services (CSS) are services that collect product offers from online merchants in order to direct users to the merchant websites in order to complete the sale there. A CSS portal therefore is a price comparison portal, where different products, services and prices can be compared.

Publish Google Shopping Ads through CSS-partners
Google Shopping is a CSS itself, that keeps up to 20% of the cost per click (CPC) price as its profit margin. By using a CSS partner such as Smarketer, the Google profit margin of up to 20% is not applicable from the CPC, so your offers remain more effective.
Google allows the merchants of CSS partners to display shopping ads in the search engine page through a merchant center. These ads are then not shown as “by Google” but as “by Smarketer.”

Advertisers are now receiving a sales advantage due to 20% lower click prices. To be more precise, this means that if a merchant bid of € 1 has been submitted through Google Shopping, Google will charge a profit margin of € 0.20 and only € 0.80 will be used for the actual placement of the shopping ad.

Three steps to success

Contact us

For a quick and uncomplicated introduction, feel free to contact us risk-free. Start today and reach your full potential immediately.

Confirm the conversion

The transition and use of the CSS is incredibly simple. We only need a written conversion permit. As soon as we have it, you don’t have to do anything else.

Conversion of your merchant center

With the confirmation we will have Google do the transition to CSS. As soon as this procedure is complete, we will let you know. The procedure usually takes just a few days, but by using an express transition it can be completed in 24h.
Doubled ad presence
In order to further increase advertising presence there is the so-called “double listing.” This is an option if you let your existing merchant center run next to your merchant center with us as CSS partner via Google Shopping. This means that both merchant centers can display your ads at the same time. However, to prevent your ads from competing with each other, a user will never see the same ad twice during a search. Our Smarketer CSS specialists will be happy to discuss the best strategy for your company with you.
Our comparison portal
Our comparison portal
Through our shopping comparison portal Smarketer.Shopping, you can run Google Shopping campaigns as usual. Your advantage is that the cost per click (CPC), i.e. the price per click, will be more effective, as Google’s 20% profit margin does not apply. This means that your bids are directly higher without changing the CPCs, without increasing the effective costs.

The history of CSS
In 2009, the British comparison shopping service Foundem filed a complaint against Google with the EU competition authority that was joined by several comparison portals. The complaint was that Google was using its market position to place their own results above those from other comparison portals. This resulted in large growth in the Google Shopping Service, as alternative sites would get fewer new visitors. After negotiations, the EU commission decided to issue a fine of 2.4 billion euros. Additional fines were promised should Google not take actions to create fair competition. Firstly, the comparison platform (known as “Google Shopping”) was separated from the holding for the European market: Google Shopping Europe (GSE) is now its own business and has to remain competitive. That means that Google receives a margin of the click offer from merchants, to fund itself. Other comparison portals can also advertise on the Google Shopping platform, its financing method is subject to the respective CSS portal, the bid margin charged by Google is dropped.
