Binet (head of effectiveness at adam&eveDDB) and Field (independent marketing consultant and former adam&eveDDB strategy planner) mined the IPA Effectiveness Awards databank, the largest collection of validated marketing case studies in the world, and asked one question: what actually grows businesses over time? The IPA Databank, started in 1980, contains over 1,400 case studies from the Effectiveness Awards, each one a peer-reviewed account of marketing activity, business outcomes, and the econometric evidence linking them. Binet and Field analyzed roughly 1,000 cases for this report, the largest meta-analysis of marketing effectiveness ever conducted at the time. Their answer overturned a decade of digital orthodoxy. Brand-building campaigns (broad reach, emotional, slow burn) drive long-term growth. Activation campaigns (narrow targeting, rational, immediate response) drive short-term sales. Neither alone is sufficient. The optimal split for most categories is roughly 60 percent brand to 40 percent activation. This book is required reading for any marketer who has been told "we need to be more performance-focused" and suspects something is wrong with the argument but cannot articulate why. Binet and Field hand you the receipts.
Core frameworks
1. The 60/40 Rule
The IPA dataset shows that companies investing roughly 60 percent of budget in brand-building and 40 percent in activation generate the highest combined long-term and short-term effects. The exact split varies by category (FMCG closer to 60/40, considered purchases like cars closer to 70/30, online-only retail closer to 50/50). The split also varies by company maturity: established brands defending position tend to optimize closer to 60/40, while smaller brands building category presence sometimes need 70/30 or higher brand investment to escape the Sharp double-jeopardy trap.
The mechanism behind the split: brand-building campaigns build mental availability and pricing power over time, both of which compound into easier and more profitable future activation. A brand that has been continuously built carries 3 to 5 years of mental availability stock that translates into category buyer awareness, brand consideration, and willingness to pay. Activation campaigns convert that stock into transactions at lower cost per acquisition because the buyer is already familiar with the brand. The compounding effect means that companies running the 60/40 split for several years end up with lower customer acquisition costs and higher pricing power than companies that ran activation-heavy splits for the same period.
The Audi UK case during the 2008 recession is the book's canonical evidence. Most automotive brands cut advertising spend sharply in 2008 and 2009 as the recession hit. Audi maintained its brand-building spend through the downturn, including the iconic "Vorsprung durch Technik" campaign. The result: Audi gained market share that competitors took roughly a decade to claw back. The recession-period brand investment compounded into a long-term competitive advantage that no amount of subsequent performance marketing could replicate.
If you only remember one thing: the 60/40 split is not a guideline; it is the empirical optimum from the largest dataset in marketing.
2. The two response curves
Activation produces a sharp short spike in sales that decays within weeks. Brand-building produces a slower, smaller weekly lift that compounds over years. Plotted together, activation looks impressive on a quarterly chart and trivial on a five-year chart. Brand-building looks trivial on a quarterly chart and dominant on a five-year chart. Most digital dashboards only show the quarterly view.
The math of the curves matters. An activation campaign produces, on average, roughly 80 percent of its total sales effect within the first two weeks of the campaign, with the remaining 20 percent decaying over the subsequent four to six weeks. The total effect is measurable and short. A brand-building campaign produces, on average, roughly 20 percent of its total sales effect within the first quarter, with the remaining 80 percent compounding over the following 12 to 36 months. The total effect is large but slow. The IPA Databank's longitudinal data captures the difference cleanly because the case studies typically report business outcomes over 3 to 5 years rather than quarterly.
The reporting trap: most marketing dashboards report quarterly. Activation campaigns look like they are working; brand campaigns look like they are not. The quarterly view systematically biases marketing leadership toward over-investing in activation and under-investing in brand. The five-year view, which is what the IPA Databank captures, reverses the apparent ranking. Brand campaigns dominate; activation campaigns are useful but secondary.
How to operate: instrument long-term measurement alongside quarterly measurement. Track brand health metrics (unaided recall, consideration, mental availability, pricing power) on the same dashboard as revenue. Without long-term metrics, the dashboard is biased against brand investment.
If you only remember one thing: brand-building's effects are slow and large. Activation's effects are fast and small. The dashboard you build determines which one looks like it is working.
3. Share of Voice (SOV) versus Share of Market (SOM)
If your SOV exceeds your SOM, you tend to grow market share. If SOV falls below SOM, you tend to lose share. The gap is called Excess Share of Voice (ESOV). Each 10 points of ESOV correlates with roughly 0.5 points of annual market share growth.
The math, walked through. A brand at 20 percent market share spending at 20 percent share of category voice has zero ESOV and will roughly maintain share. The same brand spending at 30 percent SOV has 10 points of ESOV and will gain roughly 0.5 percentage points of market share annually. Over five years, that compounds to 2.5 share points of growth. The same brand spending at 10 percent SOV has minus 10 points of ESOV and will lose roughly 0.5 percentage points of market share annually. The asymmetry matters: gaining 2.5 share points through ESOV may take five years; losing 2.5 share points through underinvestment takes the same five years and is harder to reverse.
The Audi UK case quantifies this. During the recession, Audi's competitors cut spend; Audi maintained spend. The ESOV moved sharply in Audi's favor. The subsequent share gains followed the predicted trajectory. The competitors who cut spend during the recession faced a multi-year share-recovery challenge once they tried to rebuild.
How to operate: calculate your ESOV quarterly. If it is negative, raise the alarm with finance before market share erodes. The ESOV calculation requires knowing your share of category spend (which most companies can estimate from competitive intelligence or industry reports) and your share of category sales (which most companies know precisely). The ratio tells you whether your current spend is consistent with share defense or share growth.
If you only remember one thing: ESOV predicts share movement. Calculate it before the share has moved.
4. Emotional versus rational creative
Campaigns rated "emotional" by judges outperformed "rational" campaigns on every long-term business metric (profit, share, penetration, pricing power) by a factor of roughly 2x. Rational campaigns only outperformed on short-term sales response. The implication: rational arguments win the transaction, emotional resonance builds the brand that makes future transactions cheaper.
The IPA Databank's coding methodology distinguished between campaigns whose primary appeal was rational (product features, comparative claims, evidence of superiority) and campaigns whose primary appeal was emotional (humor, storytelling, identity, social belonging). The coding was done by independent judges before the business outcomes were analyzed, so the classification was not biased by the outcomes. The results: emotional campaigns produced roughly 2x the long-term business effects of rational campaigns at the same spend level. The pattern held across categories and time periods.
The mechanism: emotional creative is more memorable, more shareable, and more associated with the brand than rational creative. The customer who encounters a feature-comparison ad processes it briefly and forgets it. The customer who encounters an emotionally resonant ad carries the memory forward and associates the feeling with the brand. The mental availability that results compounds into easier future activation.
Cadbury's "Gorilla" ad (2007) is one of the cleanest examples. The ad shows a gorilla playing the drum solo from Phil Collins's "In the Air Tonight." There is no product in the ad until a brief Cadbury Dairy Milk logo at the end. The ad has no rational claim, no feature comparison, no benefit statement. Cadbury's UK market share grew substantially in the years following the ad's launch, and the campaign's ROI was measured in the hundreds of millions of pounds. The same budget spent on rational creative would have produced a fraction of the long-term effect.
If you only remember one thing: emotional creative compounds. Rational creative converts. The 60/40 split rewards the compounding.
5. Fame as the lead metric
The single creative effect most predictive of long-term business growth was "fame" (whether the campaign became talked-about, shareable, culturally noticed). Fame outranked information, awareness, persuasion, and differentiation as a leading indicator of profit growth.
The IPA Databank's fame metric was measured through specific indicators: cultural references in non-marketing contexts (news coverage, social media discussion, parody, the campaign entering the cultural vocabulary), earned-media reach beyond paid amplification, brand-search lifts during the campaign period, and qualitative survey items about whether the campaign was being talked about. Campaigns that scored high on fame produced disproportionately strong long-term business outcomes, controlling for spend.
The mechanism: a campaign that becomes famous extends paid reach through earned media at no additional cost. The cultural footprint of the campaign continues producing impressions and conversations long after the paid media has stopped running. Cadbury's "Gorilla" continued generating Google searches and YouTube views for years after the original campaign window. The Old Spice "Man Your Man Could Smell Like" campaign continued generating cultural references for nearly a decade. The fame multiplier is meaningful enough that the IPA's later "Effectiveness Code" research (2020) found highly creative campaigns generated 12x the business effects of safe campaigns, with fame being the primary driver.
How to operate: brief creative for fame, not for "communicating the message." Emotional, distinctive, talked-about work is the lever. The brief that asks "how do we get our message across" produces forgettable creative. The brief that asks "what would make this campaign culturally noticeable" produces the rare hits that compound.
If you only remember one thing: fame is the leading indicator of long-term growth. Brief for fame, not for message clarity.
Actionable takeaways
- Audit your current budget split. If you are spending more than 60 percent on activation channels (paid search, retargeting, performance social), you are likely under-investing in growth.
- Stop measuring brand campaigns on click-through and conversion. Use awareness, consideration, mental availability, and pricing power as the right scorecard.
- Calculate your ESOV quarterly. If it is negative, raise the alarm with finance before market share erodes.
- Brief creative for fame, not for "communicating the message." Emotional, distinctive, talked-about work is the lever.
- Defend brand budget during downturns. The dataset shows brands that maintain or increase SOV during recession come out the other side with permanent share gains.
What this book is NOT about
This book does not teach you how to make creative work. It is not a craft manual. It is an econometric argument about how marketing budgets should be allocated and how effects should be measured. If you are looking for tactical guidance on running a Facebook campaign or writing a TV ad, look elsewhere. If you need ammunition to defend a brand budget to a CFO who only believes in last-click attribution, this is the most-cited source in the field.
Two specific misreads to avoid. First, "60/40" is not a literal universal target. The split varies by category, by company stage, and by competitive dynamics. The 60/40 is the empirical average from the IPA dataset, which skews toward established UK brands across multiple categories. Smaller brands or category challengers often need higher brand investment (70/30 or even 80/20) to escape the double-jeopardy trap that Sharp's "How Brands Grow" describes. Operators who treat 60/40 as a literal target without considering their specific context produce worse outcomes than operators who use the framework as a directional guideline. Second, "emotional creative" is not "creative without information." The IPA's emotional category includes campaigns that convey product information through emotional vehicles (storytelling, humor, identity). The discipline is using emotional vehicles to carry the message, not abandoning the message in favor of emotional flourish.
Field updates since publication: Binet and Field returned with "Media in Focus" (2017) to test whether digital had changed the rules. The answer was that the 60/40 rule still held, and the share of voice and emotional creative findings still applied, with the addition that reach beats targeting in most digital contexts. The 2020 "Effectiveness Code" further extended the framework with the creative multiplier finding. The trilogy together represents the most empirically rigorous treatment of marketing effectiveness available. The most credible contemporary critique: the IPA Databank skews toward UK markets and toward case studies that won effectiveness awards (which selects for measurable success), which means the findings may underweight categories where the 60/40 rule does not hold cleanly.
