The latest probe order follows a complaint by a person named Vishal Gupta who owns a group of remote technology support service firms. He complained to the commission that his advertisements were unfairly terminated by Google.
Mr. Gupta paid Google $310,000 for ads, but the advertisement were later blocked by Google who said he had violated the company's "user safety policy," the commission's order said.
In his complaint to the commission Mr. Gupta claimed that "Google Inc. has a 'user safety policy' which is extremely vague and unclear giving rise to abuse of dominance by Google."
Google has its own remote technology support service similar to Mr. Gupta's called Google Helpouts. Mr. Gupta's complaint alleges Google may have been blocking his advertisements so Google Helpouts could get more customers.
