Google gets fresh complaint at EU over search engine tweaks

Officials are increasingly scrutinizing the black box of online advertising where Google automatically calculates and offers ad space.

Google is on a collision course with advertisers and publishers who fired off a fresh antitrust complaint with the European Union in the run-up to the US tech giant’s court fight over a record $5bn (€4.28bn) antitrust fine.

Movement for an Open Web, an industry group, asked the European Union to rein in how Google tweaks its search engine after the company imposed ad-tracking changes that threaten to hit advertisers’ and publishers’ revenue streams.
