In June, the Commission imposed a €2.4 million fine on Google after criticising the way the company displays product search results in the online shopping market.
At the time, the Commission said the company gave "prominent placement to its own comparison shopping service" in the search results it indexed and also demoted links to similar services run by rivals. It said Google was responsible for a breach of EU competition law as a result. Its findings concerned search results in 13 European countries, including the UK and Germany.
Google said it disagreed with the Commission's findings. It said the search results it displays reflect the wishes of consumers and that the Commission had not given sufficient consideration to the competition it faces from online platforms such as Amazon and eBay when reaching its decision.
Google has been given until 28 September to make changes to its search practices or face potential daily fines thereafter of up to 5% of its daily global revenue. The company submitted planned changes to the Commission last month.
