WhatsApp said ads will be targeted to users based on information like the user’s age, the country or city where they’re located, the language they’re using, the channels they’re following in the app, and how they’re interacting with the ads they see.

WhatsApp will be showing ads in the Updates tab which is used by 1.5 billion people every day across the globe.

They will appear in only one part of the Meta-owned messaging service, it said. The move is potentially lucrative, while raising questions about user privacy.
