Google bosses from its Ads, Chrome and Search departments conspired together to boost ad revenue, according to emails shared at the federal antitrust trial by the US Department of Justice. The internal emails reveal private exchanges between Jerry Dischler, the Vice President of Google Ads, Prabhakar Raghavan, who heads up Google Search and Chrome, and Anil Sabharwal, Product VP and GM at Google, as well as other senior leadersWithin those conversations, the Google bosses discussed increasing search queries on Chrome to improve ad revenue – which accounts for more than 80% of Alphabet’s revenue. Search marketers have long speculated that Google intentionally complicates SEO to boost ad sales revenue. Despite denials from Google search leaders like John Mueller, this email exchange seems to indicate otherwise, indicating potential unfair impacts on SEO campaign performance. On 8 May 2015, Mueller was asked by a marketer if Google makes SEO harder to boost ad revenue.
