There was less need for the searchers to look even further on the third-party sites, because Google Shopping also compares products. Because the comparison websites were not allowed to advertise in Google Shopping, there was unfair competition according to the EU. The agreements that Google has made with the EU have actually created a kind of split between Google Shopping and Google Ads (AdWords). Google Shopping had to be able to operate as a comparison website that is separate from Google Ads. In addition, Google Shopping had to compete with all other comparison websites and therefore also be able to earn money itself.
The Google comparison website is called Google CSS (or Google Shopping Engine). The rest of the comparison websites accredited by Google are called CSS (Comparison Shopping Services) partners. What's different now? At first glance, the change is not great. The Google Shopping campaigns can still be placed in Google Ads in job function email list the same way.

Below I explain with an image what is immediately visible when someone searches for a product. [A] The link to the product on the web shop. That has not changed. [B] 'From ShopXYZ', the name of the comparator (CSS partner) that placed the ads. That is also the link to this comparator. [C] 'From Google', the ads run through Google CSS. That is also the link to Google Shopping page.
A screenshot from Google CSS with an explanation of what has changed. The difference in advertising costs due to this renewal Because the Google comparator (Google CSS) became separate from Google Ads and had to 'make money', a way was devised to split the advertising cost stream into a piece for Google CSS and a piece for Google Ads itself. Google does not share the exact values , because Google CSS is a competitor of all other comparison websites: Citation that Google Shopping currently has a fixed margin percentage on every bid.
