The arithmetic that decides it
Do this before anything else. Take your average deal value, multiply by the proportion of enquiries that close, and you have what an enquiry is worth. Divide by the proportion of clicks that become enquiries and you have what you can afford to pay for a click. If that number is comfortably above what the platform charges, the channel works. If it is not, no amount of optimisation rescues it.
This is the calculation the channel is most often sold without, and it is why LinkedIn campaigns fail in a specific way: the targeting is excellent, the leads are genuinely the right people, and the arithmetic never worked.
What actually works here
Offers that respect the setting. Nobody buys a five-figure service from an advertisement in a professional feed, so the job of the ad is to start something — a genuinely useful document, an assessment, an event — rather than to close.
And narrow beats broad. The platform’s value is precision, so an audience of four thousand exactly-right people is worth more than four hundred thousand approximately-right ones, whatever the reach estimate implies.
