Advertising on Facebook isn’t dead. Despite new players on the social media scene — TikTok, we’re looking at you — knowing how to advertise on Facebook is still an essential skill for most marketers. Right now, if you advertise on Facebook, your ads can reach 2.17 billion people — in other words, close to 30% of the world’s population. Plus, the platform’s active user base continues to grow. Sure, these are impressive numbers. But Facebook is all about getting your message in front of the right segment of those people. The users who are most likely to be interested in buying your products or services.
