Advertising Works 15
In a sentence
A curated collection of 22 prize-winning case studies from the 2006 IPA Effectiveness Awards that forensically prove how investment in marketing communications generates measurable, financially quantifiable business returns.
Advertising Works 15 is the definitive evidence base for anyone who must justify marketing spend: it assembles the top prize-winners of the industry's most rigorous effectiveness competition, where judges in 'active sceptic' mode demand honest attribution of business outcomes to communications. Across brands from Marks & Spencer to O2, Naturella to Felix, each case study quantifies the campaign's contribution using econometrics, regional analysis, controlled comparisons and payback calculations — isolating advertising's effect from price, distribution, product and promotional factors. Beyond the cases, the book adds expert perspectives on creativity, media revolution and fresh thinking, plus best-practice guides on demonstrating payback and writing multinational case studies. For marketers, agencies and finance-minded executives, it is a goldmine showing not just that communications work, but precisely how and why, and what return they deliver.
The four lenses
- Science
- Statistics
- Systems
- Strategy
The model
An inferred causal model in which design levers (creative quality, media integration, channel strategy, consistency) and contextual conditions drive psychological states (awareness, emotional engagement, attitude/brand perception, consideration) and behavioural patterns (trial, loyalty, advocacy), which in turn produce outcome metrics (sales, share, price premium, payback). Grounded in the recurring logic across all case studies of isolating and attributing effects.
Creative Quality and Distinctivenessdesign lever
The strength, distinctiveness and emotional or persuasive power of the creative idea and execution, including breaking from category norms and acting as a 'creative multiplier' of communications effectiveness across strategy, media and execution.
Media Integration and Channel Strategydesign lever
The degree to which communications are integrated across channels with an invisible join between strategy, media and creative, including optimised message distribution versus consumer-led participation, and the deployment of multiple touchpoints to surround the audience.
Campaign Consistency and Continuitydesign lever
The extent to which a campaign maintains a consistent idea, tone of voice and brand property over time rather than constantly changing, building wear-in, cost efficiency and brand value across long time horizons.
Consumer Insight and Strategic Relevancedesign lever
The degree to which communications are built on a fundamental human truth or fresh consumer insight that makes the message relevant, emotionally resonant and capable of changing entrenched behaviour, including reaffirming local cultural roots.
Competitive and Market Contextcontextual condition
The external conditions in which the campaign operates, including category growth or decline, competitor activity and share of voice, regulatory constraints, and cultural attitudes that moderate the strength and nature of communications effects.
Advertising Awareness and Saliencepsychological state
The extent to which the target audience notices, recalls and recognises the advertising and the brand, providing cut-through and salience as a necessary first step toward attitudinal and behavioural change.
Emotional Engagement and Affinitypsychological state
The positive emotional connection, involvement and affinity consumers feel toward the brand as a result of communications, including feeling closer to the brand and developing subconscious positive associations that drive choice.
Brand Perception and Attitude Changepsychological state
Shifts in how consumers perceive the brand's image, quality, value, status and differentiation, including overturning negative perceptions and reframing the lens through which the product is viewed.
Consideration and Brand Preferencepsychological state
The degree to which the brand enters the consumer's mental shortlist and is actively considered or preferred over competitors, increasing the propensity to choose it.
Behavioural Response (Trial, Enquiry, Switching)behavioral pattern
Observable consumer actions stimulated by communications, including trial purchase, enquiries, website visits, applications, switching from competitors and reduced evasion, representing the conversion of attitudes into behaviour.
Loyalty, Retention and Advocacybehavioral pattern
The degree to which communications strengthen repeat purchase, customer retention (reduced churn), reduced price sensitivity, and positive word-of-mouth recommendation that compounds value over time.
Sales, Market Share and Price Premiumoutcome metric
The quantified commercial outcomes attributable to communications, including incremental sales volume and value, market share gains, distribution gains and sustained price premium relative to competitors.
Financial Payback and Return on Investmentoutcome metric
The net profit return generated by communications after deducting incremental costs (retail margins, taxes, cost of goods, media and production) from incremental revenues, accounting for timing, lifetime values and adstock decay.

The story
The reader A marketer, agency strategist or finance-minded executive who wants to prove that their marketing communications investment delivers real business results.
External problem
They must justify marketing spend against hard financial criteria and isolate communications' contribution from all other factors.
Internal problem
They feel sceptical pressure, fear that advertising is an unaccountable 'black hole', and worry their work cannot be credibly proven.
Philosophical problem
It is just plain wrong to treat marketing as unmeasurable hand-waving when its effects can be forensically demonstrated and attributed.
The plan
- Study real, prize-winning case studies that quantify and analyse results.
- Isolate the effect of communications using econometrics, regional analysis and controlled comparisons.
- Demonstrate payback properly by netting incremental costs from incremental revenues.
- Apply lessons on creativity, media thinking and fresh strategy to your own campaigns.
- Use best-practice approaches for payback and multinational evaluation.
Success
- You can prove beyond reasonable doubt that your communications contributed more than they cost.
- You win boardroom credibility and ongoing investment in marketing.
- Your campaigns become more effective, efficient and financially valuable over time.
At stake
- Your marketing is dismissed as an unaccountable black hole and budgets are cut.
- You misattribute results, overstate payback, and lose credibility with finance.
- Without an effectiveness culture, brands erode and competitive advantage is lost.
