The company will be able to use information about what people are entering into its search engine to target adverts according to users' interests under the changes. It will collate data to create a single profile for each user across 60 of its services including Gmail and YouTube. But concerns have been raised over the privacy implications of the move, with the French regulator claiming it may not be lawful. Peter Barron, head of communications at Google, said the firm was happy to meet with the French authorities to discuss their concerns. Speaking on BBC Radio 4's Today programme, he said users could "control and manage" their search histories by opting out or switching them off.
