Meta is introducing three new advertising features on WhatsApp, ensuring that these ads will not interfere with users' private conversations. Users can avoid advertisements if they prefer to use WhatsApp solely for messaging, as ads will not appear in their inbox. The 'Updates' section, currently operational in the UK, is gaining popularity in other regions despite being described as "not particularly popular." Users will not be able to remove the 'Channels' or 'Updates' buttons, but the WhatsApp team believes this does not negatively affect user experience. Advertising will be personalized based on users' location, language, and interactions with ads and channels, particularly for those linked to Facebook or Instagram.
