The European Commission has reportedly asked search engine giant Google to review its proposed concessions and also put in efforts to relieve concerns about dominating the search engine market.
EU's antitrust chief said that Google must do more to relieve such concerns, after rivals criticised concessions it has offered as being inadequate, Stuff.co.nz reports.
The report said that Google has offered to mark out its own products in internet search results, provide links to at least three rival sites and make it easier for advertisers to move to rival platforms.
Google spokesman Al Verney said that the company would continue to work with the EU competition authority and insisted that their proposal to the European Commission clearly addresses the four areas of concern.
Google which has a market share of over 80 per cent in Europe's internet search market could face a fine as much as 5 billion dollars if it does not resolve the issue.
The EU competition regulator has also sought feedback from Google's rivals and third parties and a number of them have said any concessions would only reinforce Google's dominance.
Lobbying group ICOMP lawyer David Wood said that the Commission must set a tight deadline failing which the commitments procedure should come to an end, the report added.
