Growth efficiency: a new metric to monitor brand health and generate future sales growth
Short-term sales efficiency is not an indicator of how efficiently a company can grow, but by measuring longer-term growth efficiency, scale-up brands can plan for profitable growth, according to a new report from WARC.
Growth Efficiency: Marketing’s Existential Metric, produced in partnership with brand tracking company Tracksuit, and WARC sibling company Perpetua, a provider of e-commerce advertising optimization and intelligence also highlights that building brand awareness drives greater effectiveness in performance marketing.
Key findings
- The Paradox of Unscalable Efficiency
A common pattern among brands seeking to scale up is that at a certain point, growth plateaus, becomes more expensive, and previously strong performance marketing metrics, such as ROI or ROAS, decline.
- Growth Efficiency and Brand Strength
High awareness brands generate more than twice the sales lifts of low awareness brands as they increase their spend. At a 10% spend increase, high awareness brands yield an average 13% sales increase, while low awareness brands yield just a 6% sales increase.
- Future demand and growth efficiency
Very low awareness brands (1-5%) with small overall sales have very high growth efficiency. But as those brands grow past a certain scale, if they haven’t built awareness among Future Demand, their growth quickly diminishes.
- Modelling growth efficiency as brands scale
When brands scale up awareness at the same time as scaling up performance spend, sales can continue to happen very efficiently and brands can grow profitably into a much bigger and much more valuable business.
Greater levels of brand awareness supports greater levels of growth efficiency. Both are critical to sustainable, profitable growth. And the latter is very much dependent on the former.

Emotional ‘positivity’ is vital to audio advertising effectiveness
Audio ads that make listeners feel more positive can “dramatically” impact consumer behaviour and deliver longer-lasting brand effects, a new study has found.
Radiocentre, the trade body for UK commercial radio, partnered with System1 to further the latter’s research into hemispheric specialisation – and the subsequent impact on advertising effectiveness.
Specifically, researchers took the findings in Lemon (2019) and Look Out (2021), written by Orlando Wood, System1’s chief innovation officer, and adapted them for an audio media context.
Hark, what a sound
Rather than focus on TV and video qualities, System1 focused instead on the creative devices that may be used in an audio ad.
Qualities appealing to the right hemisphere (associated with ‘broad-beam’ attention) include characters with vitality, ‘dramatic intimacy’, distinctive accents and music with discernible melody. Conversely, devices appealing to the left hemisphere (associated with ‘narrow-beam’ attention’) include commanded action, comparisons and claims, technical language and highly rhythmic music.
System1 analysed Radiocentre’s bank of more than 1,000 radio ad case studies, using its Star Rating, Spike Rating and Fluency Rating methodology to identify trends in effective radio campaigns.
Feel-good effect
Presenting the results of the study (called Listen Up!) at Radiocentre’s Tuning In event in London, the researcher revealed findings including:
- Audio ads that make listeners feel more positive dramatically change consumer behaviour (+8.2% more consumer action) and deliver longer-lasting brand effects.
- Radio campaigns that create more positive and less negative emotion saw large increases in word-of-mouth and uplifts in social sharing.
- Optimised audio adverts are effective at attracting attention and forming strong memories, increasing short-term effects.
- Audio ads with more right-brain features are more likely to cause longer-lasting brand effects.

Brands can ‘supercharge’ search ads with behavioural science
Updated research from Google finds that “supercharging” search results, owned content, and presence at points of sale with insights derived from behavioural science can improve ROI and growth.
The research findings can help brands respond to consumers’ increasingly nuanced and specific search queries.
Why online search matters
Three years ago Google introduced the concept of the “messy middle”, which explained how online consumers, faced with abundant information and unlimited choice, navigate using a range of cognitive shortcuts. Now the second part of its Decoding Decisions series, in partnership with The Behavioural Architects, takes that research further and outlines what brands can do.
Tracking trends in Google Search, for example, shows that consumer demand is a moving target. Google suggests that marketers need to not only keep an eye on evolving trends but also invest in tools that will enable them to respond in real time, whenever unpredictable pockets of demand appear.
Takeaways
- By supercharging Search Ads with compelling aspects of behavioural science, shoppers across every category switched not just from a preferred brand to their second-choice brand, but to an invented brand created purely for the experiment.
- For established brands, supercharging ad copy with behavioural science can protect brand investment and maintain their position as a top choice for consumers.
- For challenger brands, supercharging ad copy can help level the playing field and enable them to win a greater share of clicks
- The same factors that inspire shopper confidence also drive consideration: marketers who invest in anticipating and answering the information needs of consumers may be rewarded with increased purchase consideration.
- People’s preference for specific products and services is stronger than it is for retailers. Completely invented retailers with supercharged propositions were able to attract large numbers of shoppers away from their first-choice and second-choice retailers.

How to get going on the sustainability journey
The idea of making a business or brand sustainable can seem daunting but there is a consistent set of principles that can deliver results while improving the business performance at the same time.
Why sustainability matters
The reality of putting sustainability into practice may be challenging, as it takes time and effort to succeed; but brands can get started by being clear on their moral focus and showcasing the value of their actions to the customer.

Aldi grows on the consumer shift to private label
Private-label products are at record highs, says Giles Hurley, CEO of Aldi UK and Ireland, in a sign that economic trouble remains a reality for many people despite a cooling in inflation.
Why private labels matter
To an extent, private label products are the enemy of brands (other than the brand of that supermarket) and during lean economic times or when everything is getting more expensive, private labels tend to encroach on traditional brands’ customer bases.
The Aldi equation
- Now the UK’s fourth largest supermarket, over half of everything bought at the German-originated discounter has been from its private labels, the supermarket told the BBC, with “own label products growing at twice the rate of branded goods,” said Hurley.
- Two thirds of UK households are now buying from Aldi, according to Hurley, with many of those purchases made up of Aldi’s typical mix of own-brand products. Eyeing a greater opportunity, Aldi said on Monday that it was planning to open a further 500 UK stores in the coming years.
- This week, the company posted strong results even if it noted that many shoppers continued to be “under real pressure”. However, there is now pressure on the discounters as traditional supermarkets also accelerate their price cuts; for the first time in months, Aldi and Lidl lost some ground to traditional rivals, according to Kantar data reported by the FT.

A greenwashing crackdown is coming
As a Vienna commercial court finds Austrian Airlines misled passengers over claims about sustainable flights, the EU has taken another step towards a complete ban on greenwashing.
What’s happened
The airline said that flights to an art show in Venice would be fueled with 100% sustainable fuel. But only 5% derived from renewable resources, according to a copy of the court decision the airline was required to post on its website and social media account where the original ad appeared. It was also made to pay the costs of the consumer-protection association that brought the case against it, Bloomberg reports.
Why it matters
The sanction on Lufthansa-owned Austrian Airlines amounts to little more than a slap on the wrist but a new EU law will outlaw such practices altogether (although not until 2026), Euractiv reports.
- Airlines will no longer be able to use carbon offsets to suggest flying is climate-neutral.
- Generic environmental claims will require proof of recognised performance.
- The use of terms such as “eco” or “natural” will need to be backed by evidence.
- Manufacturers' labelling will need to display expected product lifetimes.
Key quote
“We are clearing the chaos of environmental claims, which will now have to be substantiated, and claims based on emissions offsetting will be banned” – Biljana Borzan MEP.

Apple’s plan to change sport
With its arrival in the world of sport broadcasting, Apple is now working on the experience of watching sport as if it’s an Apple product, a process that requires it to go beyond the typical influence of a broadcast partner.
Why Apple’s adventures in sport matter
Apple appears to have slickly made its move into sport broadcasting to catch a wave of interest and subscribers. However, for the company, the deal was as much about the ability to innovate and keep a focus on the product beyond a traditional rights deal, explains an Apple senior executive.
What is interesting about the tech giant, which is undeniably a brand of special fascination for many marketers, is that its size and ambition is so vast that it can sometimes leave executives worrying that ideas aren’t big enough to make a mark (after all, it made $81 billion in the three months ending July). As a result, it can sometimes miss opportunities – MLS season pass was almost one of these.
What’s going on
Lionel Messi’s move to the US – a boon not just for his team Inter Miami, but for the entire MLS – has drawn increasing attention, not least because of his very novel deal with Apple: he is reported to be receiving a cut of the revenue from subscriptions to the iPhone maker’s MLS season pass.
Sport is an increasingly vital element of big tech’s entry into TV entertainment, with sport one of the most reliable ways to gather and retain a big audience. Apple is no exception, but it wanted to add new features and a uniquely good experience for subscribers.
GQ’s sports vertical interviewed Apple’s Eddy Cue, SVP of its services division – a $21 billion per quarter business that encompasses music, TV, news, and even fitness and health services – who confirmed the revolutionary deal with Messi.
- Early innovations included the idea of a “close game” notification, in which subscribers can be alerted to a tight finish they might otherwise miss.
- But Apple’s ambitions went much further: not least the right to broadcast every single game played in the league (usually, parcels of games are divided and sold to different broadcasters). “I was positive: we're not going to get in the game of playing here if we have to play by those rules,” Cue told GQ.
- Other adaptations are less revolutionary but help simplify the experience, both for fans at live games and for subscribers. Games now take place at 7:30pm, local time, on Saturdays and the occasional Wednesday (rather than throughout the week as they used to).
Key quote
“We like to design things in a way that they're simple and intuitive and beautiful for people. And we always start the process with building a great product,” Oliver Schusser, VP, Apple Music & International Content, quoted in GQ.

Sound good to you?
Sound can often be an afterthought to visuals when it comes to advertising, but it’s possible to target particular emotions – and emotions are important drivers of engagement – with particular sounds.
Why sound matters
A more nuanced understanding of how people respond to sound can help advertisers, for example, make smarter choices of music for their campaigns in order to elicit reactions that will help drive chosen KPIs.

Amazon Prime Video gets ads
The internet giant’s streaming service, Amazon Prime, will start to include advertising from early 2024 across select markets in the US and Europe, as the company seeks to monetise its audience beyond its membership fee.
Amazon announced the changes in a blog post, explaining the move as a way to sustain investment in content and noting its “aim to have meaningfully fewer ads than linear TV and other streaming TV providers”.
The rollout will begin in the US, UK, Germany, and Canada in early 2024, followed by France, Italy, Spain, Mexico, and Australia later in the year.
Why Amazon Prime Video ads matter
This isn’t entirely new territory for Amazon: advertising has taken a TV-esque form in its NFL Thursday Night Football broadcasts in the US and across its football and rugby coverage in the UK. In addition, its Freevee service (FKA IMDb TV) is already an ad-supported video-on-demand service.
The complication, of course, is that viewers of Amazon Prime Video are already paying a fee, though they will have the option of paying a bit more to have no advertising. However, given that the core benefit of membership is the fast shipping, it’s likely that inertia will keep most subscribers with the service.
It is a large and significant opportunity, with Amazon Prime’s more than 200m members now addressable through the one-stop retail shop of brand-led creative video advertising, right through to the point of purchase.
In context
From a more or less standing start at the end of the last decade, Amazon has established itself among the ‘big five’ advertising firms. In its specialist area of retail media, Amazon is expected to take a global share of 37.2% of all spend, according to WARC forecasts.
For Amazon, this has manifested as a consistent area of extreme growth during its conversations with investors.
- While most of the growth in Amazon’s advertising business comes from performance, studies are beginning to suggest that the company’s advertising is capable of helping brands’ sales beyond Amazon.
- The will to spend on Amazon advertising is clearly high, but recent research from Tracksuit and WARC indicate that awareness scores remain vital to brands looking to perform on Amazon – effectively, performance is not enough.

Marketers are ‘missing out’ on attention by not focusing on auditory content
In the battle for attention in busy front rooms – including distractions from second screens, children, pets and good old-fashioned conversation – audio is a key weapon for advertisers, a new study concludes.
Why auditory attention matters
The majority of advertising attention research has focused on visual media, often via eye-tracking technology. This approach has helped brands to move beyond viewability as a measure of ad effectiveness. However, it may fail to fully capture the multisensory nature of human attention.
The big experiment
New research, commissioned by Thinkbox, the trade body for UK commercial TV, and carried out by Dr Alastair Goode, a cognitive scientist from Gorilla In The Room, set out to understand how much attention brand advertising can gain when consumer eyes are focused on other tasks.It was the follow-up to a 2022 study (Giving attention a little attention), which compared business research with academic literature on attention to advertising.
Participants were asked to watch video ads while performing different tasks, including: listening to music; scrolling an Instagram-style feed of images; listening to speech; reading posts on X (formerly Twitter); reading a web page; texting; and having a conversation.
The study found that auditory memory consistently outperformed visual memory (72% vs. 60%), and that people are able to process and retain numerous audio cues (including spoken messages, sonic brand assets and jingles) without paying visual attention to an ad.
“If you aren’t maximising auditory content then you’re missing out,” concluded Goode.
Takeaways
- Audio is the most important thing to consider when people are not fully paying attention to an ad.
- Audio-visual is more than just audio plus visual: brands can use them together when forming a narrative.
- Visual attention does not automatically guarantee an ad will end up in memory.
- Media and creative, as well as psychological factors, are important in producing outcomes.

Targeted online ad campaigns face profitability problem
Advertisers should be cautious when running targeted online ads because this practice is less likely to be profitable than simply running an untargeted campaign, a study finds.
The research looked at what audience segments advertisers should select for randomized controlled trials and found that the more narrow the audience segment, the less likely you will break even, much less become profitable. The authors attributed this to the role that data cost and reach play in profitability.
Why targeting matters
In 2018, global digital ad spend surpassed television ad spend for the first time. The primary appeal of online ads is their capacity to target users more strategically, based on user demographics and online behaviour.
Intuitively, targeting should increase an advertiser’s profit by allowing the advertiser to stop wasting money on people who aren’t interested in a brand’s products; but targeting comes with extra costs and it reduces the number of reachable people, which can affect conversion and click-through rates.
Takeaways
- Researchers examined how a targeted ad campaign can be as profitable as an untargeted one, by developing a model that considers the trade-off between reach, cost, and performance (i.e., effectiveness).
- Targeting extremely narrow segments is ‘highly unprofitable’ due to the large increase in performance needed (in click-through rates and conversion rates) to compensate for the loss in reach.
- One experiment looked at running campaigns on Spotify: approximately half of the audience segments tested required the click-through rate to double compared to an untargeted campaign, which is unrealistically high for most ad campaigns.
- The introduction of Apple’s ATT suggests ‘that advertisers benefit less from targeting narrower audiences with growing restrictions on third-party data’ because the true reach of audience segments might be overestimated.
- ATT more negatively affects the click-through rate of narrow (versus broad) audience segments.
Key quote
‘Our paper provides ad agencies with important arguments for why they must meticulously evaluate the profitability of narrow audience segments before committing to them’ – study authors, ‘Overwhelming targeting options: Selecting audience segments for online advertising’.
About the study
An Austrian ad agency designed broad, narrow, and no-targeting strategies for one of its clients (a car dealer in Vienna), to compare their profitability. The budget was 5700 euros and the experiment lasted three months.
A second study looked at running a campaign on Spotify, while a third assessed the impact of Apple’s ATT framework on 86 different campaigns from six advertisers in diverse industries.

Print power in India: a medium driving intimacy at scale
The print media in India not only enjoys trust and credibility but also allows brand activations to work well due to its high involvement and attention – a reason why brands continue to leverage it for categories such as FMCG, automobiles, real estate and luxury goods.
Why print power matters
India’s print readership is rising and the medium is a critical part of today’s media mix for certain categories because newspaper content can be customised according to the brand’s regional and hyperlocal needs in a diverse country.

Nestlé reassesses its approach to creativity
“Creativity can be more effective,” argues Nestlé’s global chief marketing and digital officer at DMEXCO – putting a particular emphasis on the words “can be”.
Why creativity matters
Speaking at the conference, Aude Gandon added: “It can be more diverse, it can be more responsive, it can be more valuable, and it can be more effective – but it can only be [those things] if we know how to leverage these [digital] tools, if we know how to handle the opportunities that we have ahead of us.”
It’s significant that she refers to digital tools, noting that effective content around the world – and she cited the WARC Effective 100 in support of her contention – often does not include a TV ad anymore.
Takeaways
- “Don’t get too enamoured by the plumbing” is effectively Gandon’s version of not being distracted by the latest shiny new thing. Tech is the foundation of marketing, not the end product, she said: success is about pairing your existing expertise in the fundamentals of marketing – which have never changed – and amplifying that with the tools of the time.
- For example, Nestlé’s Creative X tool, powered by AI, has freed up teams from a digital checklist and enabled a 66% increase in ROMI on Meta platforms.
- In one territory, Nestlé Content Studios was able to produce 5,000 different, personalised assets for a variety of platforms from seven master assets.
- “There’s no room for lazy marketing” in an era of ad blockers and ad-free subscriptions, argued Gandon: the bar for creativity and value is getting higher.
- Upskilling at scale is essential (and Nestlé is doing just that with its 12,000 marketers around the world) to enable proper use of AI and other digital tools in order to “unleash a whole new era of creativity”.
Key quote
“Creativity is not dead. Creativity is being reinvented and it looks pretty exciting to me” – Aude Gandon, Global Chief Marketing and Digital Officer at Nestlé.

Differentiation and the ‘deadweight’ economy
With recent reports suggesting that inflation may be stabilising, Gartner describes the new climate as a “deadweight” economy and it will involve businesses investing in differentiation to succeed, the research firm argues.
Why differentiation matters
“Branding lasts, differentiation doesn’t,” argued marketing science guru Byron Sharp, but some thinkers are beginning to disagree.
The debate between distinctiveness and differentiation has started to assume an “ideological” profile, as Mark Ritson put it, but the debate is vitally important to marketing and sets out the why and the how of the discipline. Getting around two incredibly similar words is tough, however. Check out this WARC Podcast on the topic featuring Ehrenberg-Bass’s Jenni Romaniuk and Northeastern University’s Koen Pauwels.
What Gartner says
An illuminating new blog from Gartner’s finance practice breaks down the challenges facing finance departments at major businesses, all of which are interesting, but the big ones for marketers are:
- Zero-sum growth
- Waning pricing power
Where the debate comes in
Value rather than volume becomes important for marketers in an inflationary environment, as Dom Boyd, managing director, UK Insights and Effectiveness practice at Kantar, and Felipe Tomasz, of Oxford University, explained earlier this year.
“You’ve got to design for difference in every way in your brand strategy; in your innovation, in your communications, in your experience – design for difference,” explained Boyd.
For finance professionals, too, Gartner argues focusing company investments on points of differentiation or uniqueness in a battle for market share.
Key quote
“The deadweight economy challenges an organization’s ability to meet corporate performance expectations by constraining traditional avenues for growth, pricing, investment funding, cost management, people management, and productivity gains, and deadweight economic conditions can be expected to linger through most, if not all, of organizations’ current strategic planning horizons” – Randeep Rathindran, distinguished vice president, research, Gartner Finance practice.

Advice to CMOs: learn finance lingo and protect your budgets
At a time of economic uncertainty and changing customer behaviour, which is pushing CEOs to cut costs wherever they can, it’s never been more important for CMOs to talk the language of finance if they’re to protect their budgets.
Why the CMO/CFO relationship matters
Marketing budgets are going to tighten and so marketers must show CFOs they understand changing customer behaviour by using strategies driven by financial impact, not just marketing metrics.

E-commerce the big winner from holiday sales period
US shoppers will be looking for bargains in the upcoming Amazon Prime Day and Black Friday/Cyber Monday sales – UK shoppers maybe not so much – so brands and retailers on both sides of the Atlantic will need to be alert to where their main opportunities lie.
What’s happening?
A post-pandemic burst of spending has abated and with inflation continuing to affect consumer purchasing behaviour, sale days like Black Friday and Cyber Monday are likely to be more important than ever in this year’s holiday spending plans. Volume sales will grow, but the value of sales will increase at a slower rate than last year.
Retailers will need to pitch their offer accordingly, taking note of shifting patterns of demand, while those brands not being promoted by retailers can still benefit from driving traffic and being “retail-ready”.
Takeaways
- Deloitte is forecasting a 3.5%-4.6% increase in US holiday sales this year, or around half that of 2022, although e-commerce sales are expected to grow three times as fast as the bottom end of that range.
- It’s reported that TikTok will be offering sellers, in its recently-launched-in-the-US TikTok Shop, subsidies of up to 50% as it seeks to win over holiday shoppers.
- In the UK, a minority (14% in a consumer survey by It Works Media) are regular hunters of Black Friday deals; most people (58%) believe Black Friday deals are not good value for money, so retailers could be better off focusing their holiday marketing efforts outside of this date.
- Previous research has shown that a strong seasonal campaign can positively frame brand experiences to build stronger business results beyond the critical Christmas months to the following year.
