Google was hit with a record-breaking $2.7 billion fine last month by the European Commission for breaking antitrust laws.
The EU says Google demoted rivals and unfairly promoted its own services in search results related to shopping.
While the fine is the largest antitrust judgement ever, an even bigger fine could be on the way for Google.
Reports say that EU regulators are considering another record-breaking fine for Google over its Android operating system.
The European Commission has been investigating Android after rivals complained that Google has been abusing its market dominance.
Google has been accused of limiting access to the Google Play Store unless phone makers also bundle Google search and Chrome apps.
Google has also reportedly blocked phone makers from creating devices that run forked versions of Android, as part of an anti-fragmentation agreement.
