An illuminated Google logo is seen inside an office building in Zurich, Switzerland December 5, 2018. The Justice Department has accused Google of manipulating online auctions - a multibillion dollar industry dominated by Google - with these formulas to favor its own bottom line. Dahlquist asked Juda if they had introduced changes to ad sales in a way that raised the cost-per-click by a consumer that advertisers pay. But Wendy Waszmer, a lawyer for Google, asked Juda on Wednesday afternoon on if there were ways that his ads quality team could raise prices unilaterally. Google's advertising business has been criticized by advertisers and website publishers for a lack of transparency, with both accusing Google of siphoning off too much revenue.
