Turkey's Competition Board has fined Google 196.7 million Turkish liras ($25.6 million) following an investigation against the company.
The company has been found to be violating the terms of fair competition due to unfair access to advertisement space.
The California-based tech giant had presented a defense last week on accusations that it "was abusing its dominant power in the market."
This is not the first time that Google has faced a fine by Turkish authorities. Earlier this year, it was imposed a fine of 98.3 million Turkish liras for "aggressive competition tactics."
