The Boost button is probably the most-used advertising tool on earth, and for most businesses it is the wrong one — not because boosting is broken, but because it quietly makes several decisions on your behalf, and they are usually the expensive ones. Here is exactly what it decides, what that costs, and the cases where boosting is genuinely correct.
The objective, and what it costs you
This is the big one, and it is worth showing with real numbers rather than describing.
Three campaigns we run, same ad account, same period, differing only in objective:
₹6.31 per click
Traffic objective — optimised for people who click through. 5.65% click-through rate.
₹9.39 per click
Click-to-WhatsApp — optimised for conversations started. 0.89% click-through, and an actual conversation.
₹33.13 per click
Awareness objective — optimised for being seen. 0.12% click-through rate.
💡 Five times the cost per click, decided by objective alone. Boosting a post typically optimises for engagement or reach — the top row of that list. You get impressive-looking impressions and post interactions, and you pay several times more for each person who actually visits you.
This is not a conspiracy. Engagement is genuinely what a boosted post is for. The problem is that engagement is almost never what a business wants, and the interface does not make the trade-off visible.
What else the button decides for you
Audience
A simplified picker with a fraction of the real targeting catalogue. The platform exposes roughly 284 behaviours through its API; the boost interface shows you a shortlist.
Structure
One ad set, one audience. No layered segments, so you cannot tell which audience worked — you get one averaged number and no way to act on it.
Placements
Handled for you, which is actually fine — the platform's own optimisation beats hand-pinning for most businesses. This is the one thing boosting does not get wrong.
Conversion tracking
Usually absent. Without a conversion event the platform cannot optimise toward outcomes at all, only toward engagement. This is why boosted posts feel busy and produce little.
The measurement problem
A boosted post reports likes, comments, shares and reach. Those numbers go up reliably, which is exactly what makes boosting feel like it is working.
None of them tell you whether anyone bought anything. A properly built campaign pointed at a conversion event reports cost per lead or cost per purchase — numbers you can compare against what a customer is worth to you. That comparison is the entire basis of deciding whether to spend more, and boosting does not give you the inputs for it.
When boosting is genuinely right
It does have real uses, and pretending otherwise would be dishonest.
- 1A post is organically doing well and you want more of the same. Boosting amplifies something already working, which is a legitimate and cheap thing to do.
- 2You genuinely want engagement — a competition, a community post, something where comments are the point.
- 3An event with a date, where reach among a local audience is the actual goal.
- 4You have five minutes and no campaign at all. A boosted post beats nothing, and the perfect should not stop you starting.
What a real campaign gives you instead
The right objective
Optimised toward what you actually want — a lead, a sale, a conversation — rather than toward being looked at.
Layered audiences
Separate ad sets so you learn which segment is cheaper. One flat audience averages your best and worst together and tells you nothing.
A real destination
A product page, a lead form, or a WhatsApp conversation — chosen deliberately, with the conversion event verified as firing on it.
Numbers you can act on
Cost per result, not cost per like. The number you can hold against what a customer is worth.
The honest counter-argument
Building a proper campaign takes knowledge most business owners do not have and should not need to acquire. That is a real barrier and the reason the Boost button exists and is popular.
The answer is not to learn Ads Manager. It is to use something that builds the campaign properly on your behalf — which is what this whole category of tool is for. But if the choice is genuinely between boosting and doing nothing, boost. Just know you are paying several times more per visitor for the privilege of not having to think about it.
