UK watchdog may block Google’s ad shake-up for years

- By Helen Cahill

BRITAIN’S market watchdog is examining plans to block Google for two years or more from rolling out new privacy features on its Chrome internet browser.

The Competitio­n and Markets Authority is weighing up proposals to put the update on ice over fears that it could crush advertisin­g revenues at smaller rivals.

Th e regulator has already launched an investigat­ion into the t echnology after campaigner­s warned it could harm other websites by robbing them of the data they need for advertisin­g.

Google claims the new features will protect internet users’ privacy, even though the tech giant will still be able to use similar data itself. Its ‘sandbox’ privacy settings will stop smaller websites from using cookies to collect data about visitors’ internet activity. Advertiser­s rely on cookies to target people with offers they think they will like.

Pressure group Marketers for an Open Web has told the CMA the project could hit smaller websites’ revenues by up to 75 per cent.

The CMA launched its probe on January 8, but The Mail on Sunday understand­s its investigat­ion could take two years or more.

Officials fear any changes to the browser could cause irreversib­le damage to competitor­s before the probe concludes.

The watchdog has the power to stop the rollout if it can prove that urgent action is needed to prevent significan­t harm to individual­s or businesses in the UK. The CMA can also act if it is in the public interest.

It has not yet decided what action to take, and it would need to meet a set of strict criteria before it could slap Google with an order to freeze its business activities.

Kinga Incze, founder of media consultanc­y Whiterepor­t, said: ‘ This initiative is absolutely the right one, and it is one of the first cases in the world where an authority will look at how competitio­n relates to privacy. Google’s power can make it very threatenin­g.’

The CMA’s probe comes as part of a wider crackdown on the dominance of Google and Facebook in online advertisin­g. The two control around 80 per cent of the UK’s £14 billion market.

James Rosewell, di r ector of Marketers for an Open Web, said: ‘The CMA would not be conducting an investigat­ion if they didn’t feel the evidence they have seen showed there was a significan­t case for action.’

Google said: ‘The Privacy Sandbox has been an open initiative since the beginning and we welcome the CMA’s involvemen­t as we work to develop new proposals to underpin a healthy, ad-supported web without third-party cookies.’
