The European Commission is investigating allegations that Google has abused its dominant position in online search to promote its other services, such as price comparators, the Commission announced Tuesday.
The investigation will also look into alleged abuse of exclusivity clauses that discourage sites carrying advertisements served by Google from also carrying advertisements served by its rivals.
PC manufacturers and software developers will also be questioned to see whether they were pressured by Google to make its search service the default in their products, the Commission said.
Complaints from other search service providers sparked the investigation, it said.
The companies told the Commission that Google treated their services unfavorably in its unpaid and sponsored search results. They also alleged that Google gave its own services preferential placement, the Commission said.
The Commission is particularly concerned that Google may have lowered the ranking in its search results of rival providers of services such as price comparators, in order to promote similar services of its own.
The Commission stressed that opening the investigation does not imply that it already has proof of any infringements: merely that it is looking for it. Google has been notified of the investigation, the length of which will depend to some extent on the company’s cooperation, the Commission said.
Google said it would work with the Commission to deal with its concerns.
