According to the report, the comparison shopping unit will still be a part of Google, but will be required to bid against rival services for top spots in Google's search results.
Google, a unit of United States firm Alphabet, has until September 28 to halt this anti-competitive practice or face a penalty up to 5% of its average daily worldwide turnover.
Google is to give price comparison sites a better chance of attracting business through its search engine in response to pressure from European regulators.
The EU has other ongoing antitrust investigations into different portions of Google's business, including how it bundles Google services via its dominant Android mobile OS. The company continues to challenge the findings, even though it is making these changes. However, under this earlier proposal, Google had reserved the first two slots for its own ads. Instead, they argue, the ad slots in Google Shopping should be filled by an algorithm picking the most relevant offers-in much the same way as the firm selects its regular search results.More news: USA welcomes Saudi move to allow women to drive

A spokesperson for European Union Competition Commissioner Margrethe Vestager told CNBC it was "premature" for the commission to take a definitive view of the proposed remedy and put the onus on Google to obey the equal-treatment mandate imposed in June.
The fine against Google in June was among the most aggressive moves against a US technology company taken anywhere in the world. Rival price comparison services, like Germany's Idealo and a Dutch comparison site called Vergelijk, would earn money from merchants whose products, from refrigerators to electronic gadgets, they are advertising. "The industry is on its knees, and this is not going to put it back", said Mr. Stables, who has made a decision to participate in Google's new auctions despite misgivings.
"Google Shopping will compete on equal terms and will operate as if it were a separate business participating in the auction in the same way as everyone else." said Verney. Google will report to the EC on this issue every four months.
Google says it thinks the remedy is unwarranted. Google presented its plans to the commission at the end of August but did not make them public until Wednesday.
