Google seems to have violated EU competition rules with restrictive terms for third-party websites using its search advertisements, the European Commission says.
The EU's executive has informed Google of concerns that it has "hindered competition by limiting the ability of its competitors to place search adverts on third-party websites," said EU Competition Commissioner Margrethe Vestager.
This "stifles consumer choice and innovation," she added.
The findings put Google at risk of hefty fines if it refuses to cooperate with the European Union and change its procedures. It is the third time the commission has gone after the US internet giant for suspected competition violations.
Google has 10 weeks to respond to the concerns regarding online search advertising.
