Google is fast becoming the business authorities regulators all over the world want to inquire.

The Silicon Valley giant’s latest troubles come from India. After a three-year investigation, the antitrust authority in India, repeating similar criticisms in Europe, sent a report summarizing its concerns about anticompetitive behavior and search dominance to Google.

The Indian commission adds to growing international examination about how Google manages. The business is apparently facing a form of contagion that is regulatory, with accusations in one authority jumping across edges and emboldening authorities and opponents elsewhere.

The largest of these risks is in Europe, where the firm has charged with abusing its dominance in hunt to help some of its own services and is also investigating other possible breaches linked to Google’s Android cell phone applications.

The conclusions of the European Commission will likely affect regulators in other areas.

“In many ways they take their cue from what the senior and much more seasoned bureaus do.”

In two decades, Google has grown from a tiny startup to one of the biggest firms in the world. However, the cost for sway and this scale is an expanding record of regulatory woes which could result in billions of dollars in fines and demands for it to shift its business practices to adapt local laws.

While the West Coast house is called by the search giant, the bulk of its own users are at present outside America, which has left the business open to regulatory examination that regularly goes beyond what American officials have called for.

“It is an outcome of their prominence, and I believe in lots of bureaus you’ve got, country by country, a lot of affected businesses going to the competition bureau saying, ‘You need to do something,’ ” Mr. Kovacic said.

India, in particular, has eventually become a critical market for American Internet companies such as Google and Facebook, which are mostly shut out of China. Sundar Pichai, Google’s incoming chief executive, was born in India, as well as the firm has formed a huge drive in the nation through applications like Android One, an effort to make a smartphone for less than $50.

But those strategies could be challenged by regulatory inspection.

While not expressly related to Google’s continuing antitrust troubles in Europe, the accusations, predicated on a charge by the matchmaking site Bharat Matrimony as well as the watchdog group Consumer Unity & Trust Society in India, are similar.

In what’s inclined to be a succession of hearings, after which it may reject the report, request an additional investigation or accept it in whole or in part, India’s contest commission will receive stimulation from both Google and the complainants.

The organization is probably going to assert that, as of yet, no authority has found its search results to be anticompetitive, and that there’s no legal foundation for the rivals to order what it sets in its search results of Google.

“We are now reviewing this report from the C.C.I.’s continuing investigation,” a Google spokeswoman said in an e-mail statement. “We continue to work closely with the C.C.I. and stay convinced that we comply completely with India’s competition laws.”

In Brazil, an investigation started a couple of years back into whether Google used its advertising system to favor its own services over those of competitors.

Reflecting language Brazilian officials said they were reviewing grievances about Google’s shopping service, which opponents say was given greater visibility in search results over competing cost-comparison products. The case was based on criticisms from Microsoft and Brazilian competitors like Bondfaro and Buscape, according to regulatory records.

South Korean opposition authorities also raided the local offices of Google inside their own two-year antitrust investigation associated with the Android mobile applications of the firm, after finding no wrongdoing, however they finally dropped the case in 2013.
