How to Brief Your Agency on a Shopper Marketing Campaign

‍

Every agency has a story about a brief that was three bullet points and a deadline. Every one of those stories ends the same way — with a round of revisions that could have been avoided if the brief had actually done its job the first time.

‍

What a Brief Is Actually For

‍

A brief isn't a task assignment. It's the transfer of everything the agency needs to make good decisions without you in the room — the business context, the constraints, the audience, and what success actually looks like. A thin brief forces the agency to guess at all of that, and guesses cost revision rounds.

‍

The Non-Negotiables

‍

Start with the actual business objective, not just the tactical ask. "We need in-store displays" is a tactic. "We need to defend share against a competitor's new product launch in Q3" is an objective, and it changes what a good display actually looks like.

Name the specific retailer or retailers, because shopper marketing lives inside each retailer's own environment, rules, and promotional calendar. A brief that says "retail" generically forces the agency to either guess or come back with questions that delay the whole timeline.

Include real budget parameters, not a vague range designed to see what the agency proposes first. Agencies build fundamentally different ideas at $50,000 than at $250,000, and a brief that hides the number until after the pitch wastes everyone's time.

Define success in measurable terms before the work starts, not after. If nobody agreed in advance what winning looks like, every result becomes a debate instead of a scorecard.

‍

What Most Briefs Skip

‍

Competitive context is one of the most commonly missing pieces — what a competitor is doing at the same retailer, in the same window, matters enormously to how a campaign should be built, and agencies rarely get told. Past performance data is another gap: if a similar campaign ran last year, the results — good or bad — belong in the brief, not discovered after the new campaign underperforms the same way.

‍

The Bottom Line

‍

A strong brief takes more time upfront and saves far more time on the back end. The brands that get the best work out of their agencies are, almost without exception, the ones that hand over the clearest brief.
