Consumer packaged goods advertising has quietly become two businesses wearing one name. The older one buys attention: broadcast, out of home, print and brand social, aimed at making a product familiar enough that a shopper reaches for it without thinking. The newer one buys placement at the moment of purchase, through retail media networks, marketplace search, shopper marketing and trade promotion, where the decision is made in front of a shelf or a search results page. Most brands need both and almost no agency is genuinely excellent at both, which is why the first question in any agency conversation should be which of the two problems you are hiring them to solve this year.
The channels, and which agency type owns each
Brand advertising, meaning creative development, broadcast, out of home and brand led social, sits with creative agencies and the media buying shops attached to them. Retail media, meaning sponsored placement inside a retailer's own site and app, sits with commerce specialists who live in those platforms daily and understand how each retailer's auction behaves. Shopper marketing and trade covers in store display, promotions and the negotiation with the retailer, and it is often handled by a specialist or in house team rather than an advertising agency at all. Direct to consumer, where you own the transaction, needs paid social, marketplace search and a competent product listing operation. A brand that hires a brand agency and then wonders why marketplace sales did not move has bought a perfectly good answer to a different question.
What brands keep in house and what they hire out
The stable pattern is that brands keep the things that require product knowledge and relationships, and hire out the things that require volume and specialist platform skill. Positioning, packaging decisions, retailer relationships and pricing almost always stay internal, because nobody outside the company can carry the retailer conversation. Creative production, media planning and buying, retail media management and analytics are commonly outsourced, because they need people and tooling that a lean brand team cannot justify. The awkward middle is content production for marketplace listings and social, which sits between the two and is frequently under resourced in both places. Ask any prospective agency where it draws that line and whether it expects your team to supply assets, because a retainer that assumes an internal studio you do not have will underdeliver from month one.
Claims are where CPG advertising actually gets expensive
Every product claim on a package or in an ad has to be substantiated before it runs, and the responsibility sits with the advertiser rather than the agency. The FTC's guidance for small business advertisers sets out the basic requirement that claims be truthful, not misleading and supported by evidence, and its guidance on making effective disclosures in digital advertising is explicit that a qualifier hidden in small print, behind a more link, or in a place the reader must scroll to is not a disclosure at all. Health, environmental and comparative claims each carry their own substantiation burden, and in a short vertical video there is very little room for a qualifier, which is exactly why they get dropped. Build claim review into the production schedule rather than treating it as a legal step at the end.
Measurement, and the marketplace listing that ties it together
Brand advertising and retail media report on incompatible timescales, and mixing them into one dashboard usually flatters the second and starves the first. Measure retail media on incrementality where the platform supports it rather than on attributed sales alone, since the shopper who was going to buy anyway is not a result. Measure brand work on the slower indicators you agreed in advance. On owned ecommerce, structured product data and accurate listing information decide whether your items appear correctly in search results and shopping surfaces, which is unglamorous work that outperforms most creative decisions. When you are comparing advertising companies for this category, weight platform depth and claim discipline over showreel quality, because the showreel is the part of the job that is easiest to admire and hardest to attribute.
Questions people ask about cpg advertising
Should a small brand buy retail media before brand advertising?
Usually yes. Retail media meets a shopper who is already deciding, reports faster, and works at budgets that would be invisible in broadcast. Brand advertising becomes worth funding once distribution is wide enough that familiarity actually converts into pickup.
Who is responsible if an ad claim turns out to be unsupported?
The advertiser, primarily. Agencies can share liability where they knew or should have known a claim was unsupported, but the brand cannot delegate the substantiation obligation. Keep the evidence file for every claim, and keep it current when the formulation changes.
Do influencer partnerships need disclosure in this category?
Yes, whenever there is a material connection such as payment, free product or an affiliate arrangement. The disclosure must be clear and conspicuous where the audience actually sees it, and the brand is expected to brief and monitor rather than leave it to the creator.
How do I compare two agency proposals that look alike?
Split each into channel management, creative production and analytics, and ask for a price and a named team against each. Then ask what assets they expect you to supply. Most of the difference between two similar quotes lives in production scope and in who is actually assigned.
