Advertising works 15 proving the effectiveness of marketing communications case studies from the IPA Effectiveness Awards…

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.

Key ideas it contributes

• Creative Quality and Distinctiveness — 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 Strategy — 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 Continuity — 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 Relevance — 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 Context — 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 Salience — 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 Affinity — 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 Change — 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 Preference — 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) — 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 Advocacy — 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 Premium — 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 Investment — 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.
