Antitrust complaints hit Google on Monday after a Danish online job search competitor filed a complaint with EU regulators alleging that Alphabet unfairly favored its job search service.

The complaint could speed up a Google search for Jobs by EU cartel boss Margrethe Vestager, three years after it was first investigated. Since then, the EU has not taken any concrete action in  ​​online job searches.

The European Commission and Google did not immediately respond to requests for comment outside business hours.

Google, which Vestager has fined more than 8 billion euros (about 66,220 kroner) for various anti-competitive practices in recent years, previously said it was making changes in Europe following complaints from online job seekers. Launched in Europe in 2018, Google for Jobs was criticized by 23 online job search websites in 2019. They said they were losing market share after claiming the online search giant used its market power to push its new service.

Google services link to posts collected from many companies, allowing candidates to filter, save, and accept job offers even if they have to apply elsewhere. Google places a large widget for this tool at the top of primary web search results.

Jobindex, one of 23 critics three years ago, said Google had distorted the highly competitive Danish market against itself in anti-competitive ways. Jobindex founder and CEO Kaare Danielsen said his company built Denmark's largest job database, Google for Jobs, and entered the local market last year.

"However, in the short time since Google for Jobs launched in Denmark, Jobindex has lost 20 percent of search traffic due to Google's inferior services," Danielsen told Reuters.

"By placing its own bottom service at the top of the results page, Google is hiding some of the most relevant job listings from job seekers. "Employees, on the other hand, may no longer reach all job seekers unless they use Google's job services," he said.
