The biggest benefit that the advertisers get from using our price comparison service is CPC lower up to 20%. This is because the cost of clicking on ads ” via Sempai ” is not affected by any additional technological margin, as is the case with other CSSs such as Google Shopping.

The European Union antitrust ruling regarding Google Shopping

In June 2017 the European Commission imposed a record fine of 2.4 billion euros on Google for favouring its price comparison service at the expense of competitors in the Google search engine. The result of this fine is that the giant from Mountain View has allowed other price comparison engines to enter product advertising boxes.

In order to increase their share in the overall search results page display, advertisers using alternative CSS solutions are offered very favourable CPC rates by Google.

Comparison Shopping Services is a web service that collects product offers from e-sellers and redirects users who clicked on a Google product advertisement to the e-seller’s website in order to make a purchase.

CSS Sempai Shop – How does it work?

Product ads (PLA) can only be displayed as part of a price comparison service. Until recently, advertisers who wanted to increase sales through product campaigns could only use a Google product for this purpose. However, after a severe penalty imposed by the EC, Google allowed other comparison engines to auction product ads and now you can use any CSS service.

The biggest benefit of using our price comparison service for advertisers is that CPC rates are up to 20% lower. This is because the cost of clicking on ads “via Sempai” is not burdened with any additional technology margin as other CSSs, such as Google Shopping.

The only visible change resulting from the use of CSS Sempai Shop in product ads is the replacement of the link description redirecting to a product on your website from ” Via Google” to ” Via Sempai”:
