Consumer Packaged Goods Advertising: Why Share of Voice Still Wins

Consumer packaged goods advertising operates on a simple but brutal logic: brands that consistently invest in visibility grow, and brands that go quiet lose ground to competitors who do not. CPG is one of the few categories where the relationship between advertising investment, mental availability, and market share is well-documented across decades of real-world evidence. The challenge is not whether to advertise but how to allocate spend across a fragmented media landscape while keeping the fundamentals intact.

The fundamentals have not changed as much as the industry likes to claim. Reach matters. Frequency matters. Distinctiveness matters. What has changed is the number of channels competing for your budget, the pressure from retail media networks, and the temptation to over-invest in performance tactics at the expense of brand-building.

Early in my career I made the same mistake most performance-trained marketers make: I overvalued the bottom of the funnel. When I was running paid media for a range of clients, the attribution models made lower-funnel activity look like a machine. Every click, every conversion, every ROAS figure told a compelling story. It took me years to fully appreciate that a large portion of what performance was being credited for was demand that already existed, demand that brand advertising had created long before someone typed a search query. The person who walks into a clothes shop and tries something on is ten times more likely to buy than someone browsing the window. Performance marketing is often the window. Brand advertising is what got them into the shop.

What Makes CPG Advertising Different From Other Categories?

CPG brands compete at a scale and frequency that most other categories do not. A consumer might buy your product every week, encounter a competitor’s product on the same shelf, and make a decision in under three seconds based largely on habit and recognition. The advertising job in CPG is not to close a sale in the moment. It is to build the mental structures that make your brand the default choice when attention is low and decision speed is high.

This is categorically different from, say, B2B financial services marketing, where the sales cycle is long, the decision-making unit is complex, and advertising plays a supporting role in a relationship-driven process. In CPG, advertising is often the primary commercial lever. There is no account manager, no proposal process, no procurement committee. There is a shelf, a price, and a brand impression built over years of media investment.

That distinction shapes everything: how you measure success, how you allocate budget across brand and activation, and how you think about creative consistency over time. CPG brands that treat their advertising like direct response campaigns, optimising for short-term sales signals at the expense of long-term brand equity, tend to find themselves in a cycle of increasing spend for diminishing returns. The mechanics of market penetration in CPG are driven by mental and physical availability, and both require sustained investment.

If you are working through the broader commercial strategy questions that sit behind CPG advertising decisions, the Go-To-Market and Growth Strategy hub covers the frameworks that connect advertising investment to market share and revenue outcomes.

How Should CPG Brands Split Budget Between Brand and Activation?

The 60/40 split between brand-building and sales activation has been cited often enough that it has become shorthand for responsible CPG budget planning. The underlying logic is sound: brand investment builds the long-term equity that makes activation more efficient, and activation harvests the demand that brand has created. Run too heavy on activation and your short-term results look fine while your brand slowly loses distinctiveness. Run too heavy on brand without enough activation and you build awareness that does not convert at the point of purchase.

In practice, the right ratio depends on where your brand sits in its lifecycle. A new CPG launch needs to skew toward brand awareness early, building the recognition and emotional associations that will make every subsequent activation more effective. An established brand defending market share in a mature category can afford a higher activation weighting because the brand equity is already banked. A brand recovering from a period of underinvestment needs to treat brand-building as a recovery programme before expecting activation to perform.

What I have seen consistently across the CPG work I have been involved in is that brands tend to cut brand spend first when margins are under pressure, because the short-term impact is invisible. The P&L looks better. The brand health scores start declining six to twelve months later, and by then the budget conversation has moved on. It is a slow bleed that is easy to miss until it becomes a serious problem.

What Role Does Creative Quality Play in CPG Advertising Effectiveness?

Creative quality is the variable that CPG advertisers underestimate most consistently. Media planning gets enormous attention. Audience targeting gets enormous attention. The creative itself is often treated as an output of a process rather than the primary driver of whether the campaign works at all.

I think about a Guinness brainstorm I sat in on early in my agency career. The founder had to leave mid-session for a client meeting and handed me the whiteboard pen on the way out. I remember thinking, this is going to be difficult. Not because I did not have ideas, but because Guinness is a brand with such a specific emotional register that any creative thinking has to pass a very high bar before it is worth pursuing. The brand had built something over decades that was easy to dilute and hard to replicate. That experience shaped how I think about creative consistency in CPG. The brands that endure are the ones that protect their emotional territory even while refreshing their executions.

Strong CPG creative tends to share a few characteristics. It is emotionally consistent across executions even when the specific execution changes. It makes the brand distinctive and recognisable within the first two seconds. It does not confuse entertainment with communication, but the best work manages to do both. And it is built for the media environment it will actually run in, not the awards environment it might be judged in.

Having judged the Effie Awards, I can tell you that the campaigns that win on effectiveness are rarely the ones that win on craft alone. The work that drives measurable commercial outcomes tends to be clear, consistent, and built on a genuine understanding of why people buy the category in the first place. Clever for its own sake rarely moves the needle in CPG.

How Has Digital Changed the CPG Advertising Landscape?

Digital has given CPG brands more targeting precision, more measurement data, and more channel options than any previous era of advertising. It has also created a set of traps that are easy to fall into if you are not thinking carefully about what you are optimising for.

The first trap is mistaking targeting efficiency for reach efficiency. CPG growth comes primarily from light and lapsed buyers, not from your most loyal customers. Algorithms that optimise for engagement and purchase signals naturally skew toward people who already know and buy your brand. That is efficient in a narrow sense and counterproductive in a growth sense. Genuine growth tactics in CPG require reaching people who are not yet in your brand’s orbit, and that requires deliberately building campaigns that prioritise reach over precision.

The second trap is treating retail media as a brand-building channel. Retail media networks have become a significant line item in CPG advertising budgets, and for good reason: they offer closed-loop measurement and direct proximity to the point of purchase. But retail media is fundamentally an activation channel. It captures purchase intent that already exists. Brands that shift brand-building budget into retail media because the attribution looks cleaner are borrowing from the future. The logic of endemic advertising applies here: contextual relevance has real value, but it is not a substitute for the broader reach that builds brand equity over time.

The third trap is over-indexing on digital at the expense of television. TV remains the most efficient reach vehicle for most CPG categories, particularly for building the emotional associations that drive brand preference. The shift to streaming has complicated the planning process, but the underlying effectiveness of video at scale has not changed. CPG brands that abandoned TV entirely during the digital boom and then wondered why their brand health metrics were declining were experiencing a predictable consequence of underinvestment in reach.

Social and creator-led content has earned a genuine role in CPG advertising, particularly for product launches and seasonal campaigns where cultural relevance matters. Working with creators through platforms like go-to-market creator strategies can deliver authentic reach in contexts where traditional advertising feels out of place. what matters is treating creator content as part of a broader media mix rather than a replacement for it.

What Does Good CPG Campaign Measurement Look Like?

Measurement in CPG is genuinely hard, and most brands are not measuring it well. The problem is not a lack of data. It is a lack of clarity about what the data is actually telling you and what it is not.

Short-term sales uplift is the metric most CPG advertisers optimise for, and it is a legitimate signal. But it captures only a fraction of what advertising does. Brand equity metrics, mental availability scores, and share of voice relative to share of market are the leading indicators that predict whether a brand will grow or decline over the next two to three years. These metrics are less satisfying than a weekly ROAS report, but they are more predictive of long-term commercial outcomes.

When I have been involved in digital marketing due diligence for CPG businesses, the measurement frameworks I find most often are built entirely around short-term performance signals. Attribution models that credit the last touchpoint before purchase. ROAS calculations that ignore the brand investment that made the performance possible. Category share data that is reviewed quarterly but never connected back to the advertising decisions made 18 months earlier. The result is a measurement system that looks rigorous but is systematically blind to the most important effects of advertising investment.

A more honest approach starts with defining what success looks like at different time horizons. Short-term: sales activation efficiency. Medium-term: brand health metrics and share of voice trajectory. Long-term: market share relative to category growth. Each horizon requires different measurement tools and different decision-making cadences. Collapsing all three into a single dashboard optimised for weekly performance is a category error that costs brands significantly over time.

It is also worth understanding what your measurement is not capturing. Growth loops in CPG, where brand awareness drives trial, trial drives loyalty, and loyalty drives word of mouth, are almost impossible to capture in standard attribution models. That does not mean they are not happening. It means your models are giving you a partial view of reality.

How Should CPG Brands Approach Go-To-Market for New Products?

New product launches in CPG have a high failure rate, and most of that failure happens before the advertising brief is written. The product either does not solve a genuine consumer problem, does not have sufficient distribution to support a national launch, or enters a category with structural barriers that advertising alone cannot overcome.

When the fundamentals are right, the advertising job for a CPG launch is to build awareness and trial as quickly as possible in the target consumer group, while establishing the brand positioning that will carry the product through its lifecycle. Speed of trial is critical in CPG because category habits are sticky. A consumer who tries a competitor’s product before yours and finds it acceptable is much harder to convert later. The launch window matters more than in most other categories.

Distribution and advertising need to be planned together, not sequentially. I have seen CPG launches where the advertising was excellent and the product was genuinely differentiated, but the distribution was patchy at launch. Consumers saw the advertising, went to buy the product, could not find it, and bought a competitor instead. The awareness was built but the trial never happened. That is an expensive way to educate the market for your competitors.

Running a thorough analysis of your digital presence and sales infrastructure before launch is not glamorous work, but it regularly surfaces gaps that would otherwise undermine the campaign. The same logic applies to physical retail readiness. Advertising spend is wasted if the path to purchase has holes in it.

The go-to-market strategy for a CPG launch should also account for the role of the retailer. Retail buyers are not passive gatekeepers. They make ranging decisions based on their assessment of whether a brand will drive category growth, and those decisions are influenced by the quality and credibility of the brand’s marketing plan. A strong advertising commitment signals to buyers that the brand is serious about building consumer demand, which makes distribution conversations easier. The creator-led launch strategies that have worked well for some CPG brands in recent years succeed partly because they generate the kind of organic buzz that makes retail buyers take notice.

What Can CPG Brands Learn From B2B Marketing Frameworks?

CPG and B2B marketing look like completely different disciplines, and in many ways they are. But there are structural lessons from B2B thinking that CPG brands would benefit from applying more systematically.

The first is the discipline around audience segmentation. B2B marketers, particularly in complex categories, are often more rigorous about defining who they are trying to reach and why than CPG marketers, who sometimes default to demographic targeting that is broad enough to cover everyone and specific enough to resonate with no one. The corporate and business unit marketing frameworks used in B2B tech companies offer a useful structural model for thinking about how brand-level messaging and product-level messaging need to work together, which is directly applicable to CPG companies with large portfolios.

The second lesson is the value of demand generation thinking versus demand capture thinking. B2B marketers who have moved away from purely inbound, intent-based models toward proactive demand generation have learned what CPG brand managers have known for decades: you cannot just wait for people to come to you. You have to create the conditions that make them want to. The pay-per-appointment models that work in B2B lead generation are a version of the same insight: qualified demand is built, not just found.

The third lesson is around long-term brand equity investment. B2B brands are increasingly recognising, after years of over-investing in performance and lead generation, that brand matters in their category too. The BCG research on brand strategy and go-to-market alignment makes this case clearly: brand investment and commercial performance are not in tension when the strategy is coherent. CPG brands have always known this. The mistake is forgetting it under short-term commercial pressure.

Where Does CPG Advertising Go From Here?

The structural forces shaping CPG advertising over the next five years are reasonably clear. Retail media will continue to grow as a share of CPG advertising budgets, driven by retailer investment in closed-loop measurement and the appeal of first-party data. Streaming will continue to fragment the television audience, making broad reach more expensive and more complicated to plan. Creator and social content will become more integrated into mainstream CPG campaigns rather than sitting in a separate digital silo. And the pressure to demonstrate short-term ROI will continue to push budgets toward activation at the expense of brand-building.

The brands that handle this well will be the ones that maintain clarity about what advertising is for. It is not a cost to be minimised. It is an investment in future sales, and like most investments, the returns are not always visible in the quarter they are made. The BCG work on evolving go-to-market strategies is relevant here: the brands that outperform over time are the ones that make consistent investment decisions rather than reactive ones.

The measurement question will not be solved by better technology alone. It requires a more honest conversation between marketing teams and finance teams about what advertising does, on what timescale, and how to value effects that are real but not always immediately attributable. That is a harder conversation than buying a better attribution tool, but it is the one that actually matters.

CPG advertising is not a complicated discipline in its fundamentals. Build a distinctive brand. Reach as many category buyers as possible. Make the creative work hard. Maintain investment through economic cycles. The complexity comes from the number of ways the industry finds to complicate these fundamentals, and the number of incentives that push toward short-term decisions at the expense of long-term brand health. The brands that stay commercially grounded and resist the noise tend to be the ones still growing a decade later.
