Consumer packaged goods marketing is unusual because the brand rarely controls the moment of purchase. A shopper buys in a store the brand does not own, from a shelf a retailer arranges, often without ever visiting the brand's website. That breaks the tidy attribution most digital agencies are built around, and it is the single biggest reason CPG programmes go wrong when they are run like direct response. This guide explains what CPG marketing actually covers, how the retail and direct channels differ, and how to judge an agency before you commit a budget.
The three channels, and why they need different work
CPG marketing splits into three jobs that share a budget and almost nothing else. Retail is the traditional one: winning distribution, then defending the shelf with trade promotion, in-store activation, packaging that works at arm's length, and the syndicated sales data that tells you whether any of it moved units. Retail media is the fastest growing: sponsored placements and search results inside a retailer's own ecommerce environment, which behave like paid search with the retailer's own reporting attached. Direct to consumer is the third: your own store, your own subscription base, your own customer data, which is the only channel where you see the buyer. An agency that is strong in one is frequently unqualified in the others, because the skills genuinely differ. Buying media inside a retailer's platform and negotiating trade spend with a category buyer are not the same profession. Ask which of the three an agency actually does, and treat a claim of all three with more scrutiny than a claim of one.
Measurement is the hard part
In direct response you can trace a click to a sale. In CPG you usually cannot, because the sale happens in someone else's store. What honest CPG measurement looks like is a combination: syndicated retail sales data to see what actually moved off shelf, retailer-supplied reporting inside their media platforms, first-party data from whatever direct channel you have, and controlled testing where you vary spend by market or region and read the difference. That last method is the most under-used and the most trustworthy, because it produces a comparison rather than a model. Be sceptical of any agency whose measurement story is a single attribution dashboard, and be equally sceptical of one that treats measurement as impossible and asks to be judged on impressions. The reasonable middle is a small number of business metrics agreed in advance: velocity per store, repeat purchase rate, distribution gained, and cost per acquired customer in the direct channel.
Claims, labelling and the rules that bind them
CPG advertising sits inside a real regulatory perimeter, and the brand carries the responsibility, not the agency. Product claims must be truthful and substantiated before they are made, which the Federal Trade Commission's advertising guidance for businesses sets out plainly. Food and beverage labelling and the claims that travel with it are governed separately by the Food and Drug Administration, and marketing copy that outruns what the label may say creates exposure regardless of where it was published. Influencer and creator work, now central to most CPG launches, carries its own layer: the FTC's endorsement guidance requires endorsements to reflect honest opinions and material connections to be disclosed clearly and conspicuously, and that obligation covers the brand as well as the creator. Ask any agency how it briefs creators on disclosure and who reviews claims before a campaign ships. An agency without an answer is not going to be the one paying if a claim is challenged.
How to vet a CPG agency
Ask for brands by name, in your category and at your stage, with the dates the engagement ran. Stage matters enormously: an agency that has scaled a national brand with an established sales team is rarely the right partner for a brand fighting for its first regional distribution, and the reverse is equally true. Ask which retailers the team has run media inside, because those platforms differ and the learning is not transferable. Ask for a case study that names the starting distribution or velocity and what changed, rather than a percentage lift with no baseline. Ask who works on the account daily and whether they have handled a category review or a retailer reset before. And settle ownership: the ad accounts, the customer data and the creative assets should be yours from the start. Brands weighing a CPG specialist against a general growth agency usually find the deciding question is whether the constraint is media efficiency or shelf presence, because only one of those is bought with advertising.
Questions people ask about cpg marketing
How much should a CPG brand spend on marketing?
The useful framing is not a share of revenue but what each channel has to return. Trade spend is largely the cost of distribution and is negotiated, retail media should be judged on incremental units sold within that retailer, and brand work is a longer horizon investment. Set a target for each rather than a single blended budget rule.
Is retail media worth it for a small brand?
It can be, because it reaches shoppers at the point of purchase inside a retailer you already sell to, and the reporting is unusually direct for CPG. The caution is that it works best when your distribution and shelf presence already exist. Spending on retail media in stores where your product is not stocked is buying attention you cannot convert.
Should we build direct to consumer alongside retail?
A direct channel is valuable mainly for what it teaches you: which variants sell, what repeat purchase looks like, and who the buyer actually is, none of which retail data shows you. Whether it is profitable on its own terms is a separate question, and many brands run it as a research and launch channel rather than as a profit centre.
Who is responsible if an influencer makes a false claim?
Both the creator and the brand can be. The FTC's endorsement guidance makes clear that advertisers are responsible for the claims made on their behalf and that material connections must be disclosed. The practical answer is a written brief that states what may and may not be claimed, a disclosure requirement in the contract, and someone reviewing content before it posts.
