Messenger ads will be placed between dialogs on the app's home screen, just like in the social network client's newsfeed. Clicking on the ads will either take the user to the website or open a new dialog in which the user can "chat" with the advertising bot. Facebook and Instagram news feeds have long been littered with ads, but adding them to Messenger reduces the value of the app, because it is based on the principle of fast and convenient communication. Competing apps from Microsoft, Apple and Google boast a cleaner interface and ease of use. Although they still can't compete with the ubiquity of Facebook Messenger and its user base. Facebook Messenger is the most multi-user app, with around 1 billion users. The closest competitor is WhatsApp, also owned by Facebook.
