Online retailers and web services have accused Google of using its dominant position in the search market to promote its own services over those of its rivals.
According to The Wall Street Journal, travel site TripAdvisor.com, health site WebMD.com and local-business reviews sites Yelp.com and Citysearch.com and several other similar companies have cried foul over Google's alleged search engine listing tactics.
The search giant claims that the platform was meant to serve users primarily and that it is important that users get related search results, which might not necessarily be websites.
“Sometimes the most useful answer isn't '10 blue links,' but a map for an address query, or a series of images for a query like 'pictures of Egyptian pyramids.' We often provide these results in the form of 'quick answers' at the top of the page, because our users want a quick answer,” a Google spokesperson told WSJ.
