You've seen the button. A post is doing okay, and Instagram whispers: "Boost this post for R200." It feels productive. For most businesses, it quietly wastes money.
Boosting optimises for engagement, not sales
When you boost, you're telling Meta to get you likes and comments. So it finds the people most likely to engage, not the people most likely to buy. Engagement feels good. It doesn't pay the bills.
Real campaigns optimise for what you choose
Inside Ads Manager you pick an objective, sales or leads, and Meta finds people likely to take that action, using your pixel to get smarter over time. You control the audience, budget and creative.
The analogy that makes it click
Boosting is shouting your offer in a crowded room, lots of people hear you, almost none want what you sell. A real campaign is whispering it to the exact person already looking for it.
The takeaway: Boosting gets you seen. Ads get you paid. If you're spending to grow, learn to run proper campaigns, or have someone run them for you.
