YouTube, Facebook, WhatsApp, Google,,, 以前我也有過類似疑問，，，

WhatsApp, Facebook, and YouTube are popular social and video platforms that can be used for advertising

, while Google Ads is a platform for buying ad space on Google's network of websites, including YouTube, and for managing ad campaigns for Google services and other partner sites, including the new WhatsApp message extensions. Google Ads can integrate with platforms like WhatsApp to create direct messaging ads, while Facebook offers direct ad creation within its platform and YouTube runs ads that are part of the Google advertising ecosystem.
