Facebook and Instagram have made one thing extremely easy. You put up a post, it does modestly well, and a little button appears underneath offering to show it to more people for a few pounds. You tap it, enter your card details, and off it goes. Congratulations - you're advertising. Sort of.
Boosting a post is the advertising equivalent of a vending machine. It's quick, it's frictionless, it takes your money instantly, and what you get back is rarely what you actually needed. It isn't that boosting never does anything. It's that it's the shallowest possible use of a platform that can do a great deal more, and mistaking it for a marketing strategy is how a lot of businesses end up spending steadily on social media while quietly wondering why nothing much happens.
What you're actually paying for
When you boost a post, you're paying the platform to show that specific post to more people. That's it. You're not really choosing who sees it beyond a few crude options, you're not testing different messages, and - crucially - you're usually not asking the viewer to do anything except look. A boosted post gets seen. It generates likes, maybe a few comments, a warm feeling that something is happening. What it very often doesn't generate is enquiries, because it was never built to.
The metrics it produces are exactly the ones that flatter. More people reached, more engagement, the numbers ticking up. We wrote elsewhere about the difference between numbers that feel good and numbers that mean something, and boosting lives almost entirely in the first camp. You're buying the appearance of marketing rather than the substance of it.
What a proper campaign does instead
The same platforms, used properly, are genuinely powerful - which is what makes the boost button such a shame. Behind that one-tap button sits an advertising system that lets you decide precisely who to reach, show different people different messages, send them somewhere designed to turn interest into action, and measure exactly what came back for what you spent.
The difference is the difference between shouting a bit louder and actually starting a conversation. A real campaign begins with a goal - not "get seen" but "get enquiries for this specific service." It targets the people most likely to want that. It sends them to somewhere built to convert them, rather than just back to your profile. And it tells you, in pounds, what worked. Boosting does none of these things, because it was designed to be easy, not effective.
Why the button wins anyway
Given all that, why does anyone boost posts at all? Because it's right there, it's cheap, and it requires no thought. Setting up a proper campaign takes a bit of planning - deciding what you're actually trying to achieve, who you're trying to reach, and where you're sending them. The boost button skips all of that and takes your money in ten seconds flat. Of course it wins. It's the path of least resistance, and the platforms designed it that way on purpose, because a steady drip of small boosts suits them nicely.
There's nothing wrong with the occasional boost for what it is - nudging a genuinely good post in front of a few more of your existing followers. As a small tactic, it's fine. The problem is only when it becomes the whole plan : a business "doing social media advertising" that in practice means tapping boost on whatever went up that week, with no goal, no targeting worth the name, and no idea what any of it achieved.
The question worth asking
Here's the test we'd apply. Before you spend anything on social media, ask what you want to happen as a result - and be specific. Not "more awareness." Something you could actually check afterwards, like enquiries for a particular service, or bookings, or people signing up to something. If you can name it, you can build towards it and measure it. If you can't - if the honest answer is just "more of a presence" - then boosting will give you exactly that, which is to say a bigger presence and not much else.
Social media can do real work for a business. But it does that work when it's pointed at a goal, aimed at the right people and measured properly - not when you're feeding coins into a machine because the button's there and it's easy. If your social spending has quietly become a series of boosts, it might be worth stepping back and asking what you're actually trying to get out of it. We're happy to help you work that out.
