Antitrust officials had imposed the fine over how the search giant might have restricted the way that some websites displayed ads sold by its rivals.

The European Commission last year charged Google with favouring its own advertising services, opening its fourth case against the world's most popular search engine.

Google has reportedly offered to sell its AdX advertising marketplace to resolve antitrust concerns raised by the European Union. This offer comes amid increasing global scrutiny of Google’s dominance in the online advertising sector.

Following a complaint from the European Publishers Council, the European Commission opened its investigation of the search giant, charging Google with violating its antitrust laws by using its advertising technology to undermine and unlawfully block rivals.

Google this year offered to sell its advertising marketplace Ad Exchange, or AdX, to end an EU antitrust investigation. But European publishers rejected the proposal, Reuters reported this week . The news agency cited two people with knowledge of the matter but did not name them.
