Travel sites Expedia and Trip Advisor are among a group of over ten companies that are accusing Google of unfair search engine rankings in Europe.
The group is suing the the search engine giant of abusing its dominant position, a claim now being investigated by the European Commission.
On Tuesday TripAdvisor said that "anti-competitive and unfair practices by Google" harm the marketplace and consumer welfare.
"We hope that the commission takes prompt corrective action to ensure a healthy and competitive online environment that will foster innovation across the internet," Trip Advisor's statement read.
Google, meanwhile, denies that it is doing anything to hamper competition.
"We've been working closely with the commission to explain how our business works since their investigation began. We haven't seen this complaint yet, but will continue to discuss any concerns with the commission, knowing that there's always room for improvement."
EU commissioner Joaquin Almunia said a decision would be made after Easter over whether to formally charge Google.
