Google is faced with an antitrust complaint on Monday after a Danish online job-search rival took its complaint to EU regulators, alleging that the company favored its own job search service. 

Google has previously been fined more than $8 billion by Vestager for various anti-competitive practices and said that it made changes in Europe after complaints from online job-search rivals. 

Google previously too came under the microscope of EU antitrust chief Margrethe Vestager's scrutiny, three years ago, even though the EU did not take any specific action relating to the online job-search sector. 

The European Commission said that the complaint will be assessed according to standard procedures. 

"Any jobs provider, big or small, is able to take part and companies are seeing increased traffic and job matches as a result of this feature," a Google spokesperson said.

Google for Jobs was launched in Europe in the year 2018, however, it triggered criticism from 23 online job-search websites the next year. The companies said that they had lost market share after Google had allegedly used its brand value to push its new service. 

Founder and CEO Kaare Danielsen said Jobindex had built up the largest jobs database in Denmark by the time Google for Jobs entered the local market last year.

"Nevertheless, in the short time following the introduction of Google for Jobs in Denmark, Jobindex lost 20% of search traffic to Google's inferior service," Danielsen told Reuters.

Google turned the highly competitive market towards itself through unfair means, Jobindex, one of the 23 critics, said three years ago.
