Google, Meta and LinkedIn: what each channel is actually for in a show campaign
The short version. Channels are not interchangeable sources of registrations at different prices. Each one reaches a different buyer in a different state, and the cheapest registrations in a show campaign reliably come from the channel least able to tell you who they were. Judging channels on blended cost per registration will therefore point you at the wrong one. |
A show campaign brief that says "run paid across the usual channels" produces a spend split by convention rather than by function. What follows is what each channel is structurally good and bad at when the conversion is a free registration against a fixed date.
Search — captures demand that already exists
What it is for.
The buyer who already intends to attend, or who is looking for a show in your sector and has not yet chosen. They type the show name, a category phrase, or a sector-plus-city phrase. This is declared intent and it converts better than anything else in the campaign.
What it cannot do.
Create demand. The volume available is capped by how many people are already searching, and for a regional B2B edition that ceiling is low — often much lower than the registration target.
The trap.
Brand search looks like the best-performing line in the account. It usually is not doing much work: those people were largely going to register anyway. Separate brand from non-brand in reporting or the channel's contribution will be overstated and the budget misallocated toward capturing people you already had.
Where it earns its place.
Non-brand category and sector-plus-geography queries, and defending your own show name against competitors and unofficial ticket resellers.
Meta — reach and volume, at the cost of knowing who
What it is for.
Volume, geographic breadth, and reaching people whose professional identity is not well captured on a professional network — trade buyers, retailers, technicians, small-business owners. In many regional industrial sectors this is a substantial part of a genuine trade audience, and dismissing the channel as consumer-only is a mistake.
What it cannot do.
Verify professional identity. Interest and behavioural targeting infers occupation; it does not know it. You will reach people who look interested in your sector, and some proportion will be enthusiasts rather than buyers.
The trap, and it is the big one.
This channel will almost always produce your lowest cost per registration, which makes it look like the winner on the metric most campaigns optimise. If the campaign is judged on blended cost per registration, budget flows here, the headline number improves, and the buyer composition your exhibitors were sold quietly erodes. The consequence shows up eleven months later in the renewal conversation.
Where it earns its place.
Volume segments where composition matters less, walk-in and late-stage attendance pushes, and geographic expansion into markets with weak professional-network penetration.
LinkedIn — buys authority, expensively
What it is for.
Job title, seniority, function and company. When the exhibitor promise is procurement-authority buyers or technical specifiers, this is the only channel that can target the attribute directly rather than inferring it.
What it cannot do.
Deliver volume cheaply. Cost per registration here is routinely several times Meta's, and in some markets the audience simply is not large enough at the seniority you want.
The trap.
Judged on cost per registration it looks like the worst channel in the account and gets cut. Judged on cost per registration in the segment the exhibitors are paying for, it frequently looks like the best. This is the clearest case in a show campaign for reporting cost per registration by segment rather than blended.
Where it earns its place.
The procurement-authority and specifier segments, international buyer acquisition, and delegate or conference audiences where seniority is the product.
Programmatic — coverage and sequencing, not discovery
What it is for.
Staying present across the ninety-day window at low cost, sequencing messages against people who have already engaged, and reaching trade audiences through sector publisher inventory that the platforms cannot.
What it cannot do.
Prospect efficiently. Broad programmatic prospecting for a regional trade audience is usually the least efficient line in the account.
The trap.
Retargeting reports beautifully and takes credit for registrations that were coming anyway. Treat its numbers with the same suspicion as brand search.
Where it earns its place.
Sector publisher placements with real trade readership, and post-engagement sequencing.
Email — not a channel, the close
Email belongs in a campaign plan and not in a channel comparison, because it is not acquiring anyone. It is converting people the other channels already reached, plus your own past-attendee list.
Two things follow. Its cost per registration looks extraordinary and should never be compared against paid channels — it is closing demand those channels created. And it is the primary instrument in the final three weeks, when registration intent concentrates and the job stops being reach and becomes conversion.
How to choose show campaign channels by audience segment
Not as a percentage allocation across channels. As a channel choice per segment.
Work from the composition target: for each segment you need in the hall, name the channel that can actually reach that attribute, and set a cost per registration for that pairing. The split falls out of the arithmetic rather than being decided in advance.
Done that way, a campaign targeting procurement authority will look badly balanced by conventional standards — expensive channels carrying most of the budget for a minority of the registrations — and it will deliver the hall the exhibitors were promised.
The reporting rule that makes any of this legible
Report cost per registration by segment, never blended.
A blended figure will always favour the channel with the loosest targeting, which means a campaign managed on blended cost drifts toward composition nobody chose. This is the single most consequential reporting decision in a show campaign and it costs nothing to make.
Then, where the data allows, report cost per attendee by segment as well — registrations multiplied by that segment's show-up rate. Cheap registrations frequently show up at lower rates, which means the channel that won on cost per registration can lose on cost per person in the building.
Start where we start
Before we take an engagement we run a paid diagnostic on the last edition — your own numbers, what they can and cannot support, and where the measurement breaks. You keep the report whether or not we work together, and if the finding is that you do not need an agency, that is what it will say.
