Sooner or later someone will ask what the content converted at.
If you sell through supermarkets, there is no answer. You have no checkout, no pixel, no basket to attribute anything to. The honest reply is that the question does not apply, and the most common mistake in Belgian FMCG marketing is not making that reply. A number gets produced, it is soft, it does not hold up in the January review, and the line disappears from next year's plan.
So the useful work is deciding what the content is genuinely for, before anyone asks you to prove it with the wrong instrument.
What the content is actually doing
Moving units through a shelf you do not control
Your product sits on a shelf you did not design, at a price you did not set, beside a private label that is cheaper. Nothing in your marketing changes any of that. What content can do is arrive before the shopper does, so that the pack is recognised rather than compared.
Recognition is the whole mechanism, and it is why consistency of the pack on camera matters far more here than production value. A shopper scanning a shelf for two seconds is doing image matching, not evaluation.
The second audience nobody writes into a brief
There is a person at the chain whose job is deciding which brands keep their space and which get the end of an aisle during a promotion. That person notices whether a brand is visibly doing anything.
Nobody puts this in a creative brief because it sounds like the wrong reason to make content. It is not vanity, it is commercial reality: a brand that shows up in its category's feeds is easier to keep listed and easier to argue for. When someone in your business says "we need to look active", they are usually describing this correctly and lacking the words for it.
The shelf constrains the brief in ways direct selling never does
The pack on camera must be the pack on the shelf
This sounds obvious and it is broken constantly.
Packaging changes and the content does not. A promotional pack runs for a season. One chain lists the large format and another lists the small. A creator films the version in their own cupboard, which they bought a year ago, and the video sends viewers looking for something that is not there.
Send the current pack. Not a photo of it, the actual pack, in the format the chain you are supporting actually carries. If two chains carry two formats, that is two shoots or one shoot with both on the counter.
One pack, two languages
Here is the Belgian advantage, and almost nobody uses it deliberately.
Your packaging is already bilingual. The pack is therefore the one element in the whole production that works in both markets without modification, while the voice works in exactly one. That asymmetry is a production plan: shoot the product footage once, and record the spoken parts twice.
Brief it that way and a two market campaign costs meaningfully less than two campaigns, without the compromise of subtitling a Dutch video into French and hoping. The pack carries the recognition, the voice carries the belonging, and only one of them needs doing twice.
What you can actually measure
| What you can measure | What it tells you | What it cannot tell you |
|---|---|---|
| Sell out figures, where your chain shares them | Whether units moved in the weeks the content ran | Whether the content caused it, since a promotion usually ran too |
| Number of listings and facings | Whether the commercial relationship is improving | Anything about the shopper, since this is a buyer decision |
| Branded search volume | Whether people are looking for you by name rather than by category | Whether they then found you in store |
| Saves and shares on the content itself | Whether the creative earned attention | Whether attention reached anyone near a shelf |
| A question asked in a store aisle | Nothing statistically, and quite a lot qualitatively | Anything you can put in a deck |
The first row is the one that causes arguments. Content and promotion almost always run together, because that is how retail calendars work, and separating them cleanly would mean deliberately running one without the other. Occasionally that is worth doing, in one region, once, to find out.
What to agree before you start
Decide with your own team what would count as this having worked, and write it down before the first video exists. Not a conversion rate. Something like: our pack is recognised in category feeds, we have material the sales team can show the chain, and we did not have to explain what our product is to anyone in the second half of the year.
Those are all real outcomes and all defensible in January, which is the month that decides whether you do this again.

Frequently asked questions
How do we prove UGC works if we sell through retail?
You do not prove it with conversion, because there is no checkout to attribute. Agree in advance what counts as working, using recognition, listings and sales team ammunition, and hold to that definition when the review comes.
Should the creator use the exact pack we sell here?
Yes, and in the format the chain actually carries. Content showing a size or a design that is not on the shelf sends people looking for a product they will not find.
Can one campaign serve both language markets?
Partly, and this is where Belgium helps. The pack is bilingual so the product footage serves both, while the spoken parts need doing twice. Plan the shoot around that split.
Is it worth making content for the retail buyer rather than the shopper?
You are not making separate content for them, you are recognising that they see it. A brand visibly active in its category is easier to keep listed, and your sales team should be showing them what you made.
