BRUSSELS Google will provide more information on targeted advertisements and give researchers more access to data on how its products work, to comply with landmark European Union online content rules, the Alphabet unit said on Thursday.

Known as the Digital Services Act (DSA), the new rules are more onerous for Meta Platforms, Microsoft, Twitter, booking.com, Pinterest, Snap Inc's Snapchat, Wikipedia, Zalando and Alibaba's AliExpress because of their large number of users.

The DSA will go into effect on Friday and requires companies to do more to tackle child sexual abuse material and disinformation, be more transparent on their algorithmic processes, bots and targeted advertisements and to remove illegal, unsafe or counterfeit products sold on their platforms.

"We will be expanding the Ads Transparency Center, a global searchable repository of advertisers across all our platforms, to meet specific DSA provisions and providing additional information on targeting for ads served in the European Union," Google's vice president for trust and safety, Laurie Richardson, said in a blogpost.

"We will increase data access for researchers looking to understand more about how Google Search, YouTube, Google Maps, Google Play and Shopping work in practice, and conducting research related to understanding systemic content risks in the EU," she said.

The U.S. tech giant will also provide more visibility into its content moderation decisions, give users different ways to contact the company and update its reporting and appeals processes to provide specified types of information and context about its decisions.

It will roll out a new Transparency Center for people to access information about its policies on a product-by-product basis.
