Neil Christie of W+K London: how advertising really works – and what marketers don’t know

‘Advertising troubles both sociologists and financial directors: the former because they think it works, the latter because they think it does not.’ (Bullmore 1999.)

Professor Byron Sharp’s thought-provoking book ‘How Brands Grow – What Marketers Don’t Know’ aims to debunk the received wisdom of marketing via the appliance of science (to use a phrase made popular by marketing). Author Professor Sharp is the Director of the Ehrenberg-Bass Institute for Marketing Science at the University of South Australia, which sounds fairly impressive, particularly because it has ‘science’ in its name.

The book sets out to disprove the tenets of conventional marketing wisdom one by one, citing evidence-based research to prove its points. The book includes a chapter on ‘how advertising really works’ that is of particular interest to people working in the field, not least because this is a question that has been debated since advertising was scrawled on the walls of caves.

This contradicts the traditional ad effectiveness model, which assumes that people remember messages and make rational decisions based on persuasive communications.

(Much advertising pre-testing is based on that traditional model. People are asked to examine consciously their responses to rationally persuasive messages, so they respond rationally – “That claim wouldn’t persuade me to consider that product”. Even asking people to try to express how something makes them feel causes ‘cognitive bias’, a tendency towards cognitive, conscious responses.)

Sharp looks first at the sales response to brand advertising. He argues that brand advertising does influence sales but that its effects are hard to identify because:

a) few companies do enough advertising, of a good enough standard, to increase market share. So their advertising is only able to prevent competitors from stealing share. It causes sales even if a brand’s sales figures are flat, because it prevents decline in sales. If all brands in a sector advertise to increase share, they can’t all be successful. But if one brand opts out, it is likely to lose share.*

b) the effect of today’s advertising is spread out over a long time, so spend doesn’t result in sudden dramatic sales gains. This is particularly true for large brands, where current ad spend is small in comparison to historical marketing, physical presence and established saliency in people’s minds.

Most advertising affects people who won’t buy the brand for weeks (or months or years, if it’s a high ticket item like a car or a computer). So a change in weight of advertising doesn’t produce an easily-seen change in short-term sales.

Sharp’s findings, based on “reliable methodologies, such as experiments” are:
– advertising generates sales (Good news for advertising practitioners.)

– some ad copy is much more effective than others; some hardly works at all (No surprise there, or success would be simply a matter of outspending your competitors)

– creative copy without a persuasive message (rational reason to buy) can still be very sales effective

– media strategy that reaches more people is more effective than reaching fewer people more often; continuous advertising is more effective than intermittent bursts, because it counteracts memory decay.

He goes on, “As people screen out so much advertising, the challenge is to get past the brain’s screening mechanisms and generate that little emotional reaction in the direction of acceptance: ‘I will pay attention to this’. Therefore the primary task of advertising agencies is to generate ideas that viewers will notice and and will be willing to process over and over. This process must be brand-centric; it must refresh the memory structures that relate to the brand. This is a difficult task, which is why most advertising fails.”

Janene0742-1024x632It would be an over-simplification to suggest that this is a scientist’s way of saying what we know to be true from experience: work that is original and relevant is effective. Not least because advertising can be original without actually engaging people, advertising can be relevant but poorly branded, and so on. It was perhaps best expressed by Howard Luck Gossage (left) in the ‘60s.”The real fact of the matter is that nobody reads ads. People read what interests them, and sometimes it’s an ad.”

Our job is to make things that are more interesting and engaging than all the other distractions and entertainments that compete for people’s attention.

This approach is different from “traditional” wisdom about advertising, as put forward famously by Rosser Reeves in his theory of the ‘Unique Selling Proposition’ – that a brand must if possible differentiate itself through tangible product attributes and communicate those attributes positively. This view is still highly influential with many advertisers today. (That’s not to suggest that the product cannot be at the heart of moving, effective, and highly creative advertising, nor that product attributes can’t help to build the memory structures that relate to decision making: see Guinness, Apple and Old Spice. The trick is to put the product at the heart of the advertising and build strong emotional associations.)

Sharp continues, “We know that very little thinking, if any, can be described as purely rational. Emotion is a primary source of human motivation and exerts substantial influence on attention memory and behaviour… People watch movies, listen to music and read books largely for an emotional ride. They enjoy gaining the same from advertising and when they get it they pay more attention.”

Or, as we say at Wieden+Kennedy, ‘Move me, dude’.

Here’s our founder Dan Wieden on the topic:
“It’s been the same since people gathered around the campfire to hear a story. Are you a good storyteller or a bad storyteller? Make me laugh, make me cry, make me do something. Whether you do it on the Internet or on a balloon floating above me, I don’t care. Just move me, dude.”

More from Sharp: “Many companies are trapped in the intentions/preference paradigm. (The belief that persuasive advertising that influences stated brand preference is more likely to affect sales.) They brief their agencies and evaluate their work in line with this model. Consequently, they produce advertising filled with persuasive arguments (often about trivial benefits) that are rejected, misunderstood or ignored by viewers. They also produce advertising that fails to refresh or build appropriate memory structures because management’s attention is on the selling message. Such advertising fails to communicate consistently the distinctive aspects of the brand.”

It’s not that easy to remember examples of campaigns like this. Because, duh, they are unmemorable. But one that comes to mind from my past experience is Citroen. This is a company that has resisted attempts to build consistent associations and emotional attributes, and seeks to distance itself from the brand heritage that does persist as a result of provenance and product design. (French and quirky.)

So they produce generic car ads like these, which describe features like ‘the most sensational panoramic windscreen in its class’ and ‘CO2 emissions from only 99 grammes per kilometer’. Wow, I’ve been dreaming of owning a car with just that level of CO2 emissions.

(Of course, it’s not only because they are based on random product facts that these dull and charmless Citroen ads are unlikely to be remembered. It is possible to do great car ads that tell product stories – BMW did it successfully for years.)

Sharp: “Advertising works largely by refreshing memory structures; occasionally it also builds memory structures and creates a preference or intention to purchase. Advertising maintains and builds brand salience via creative publicity. Brands don’t need to worry about having a persuasive message, even when they have one, the message needs to be embedded within a framework of brand links and cues, salience and long-term distinctiveness.”

To contrast with Citroen, an example of a brand that does as Sharp suggests might be Andrex, which has been a leader in the toilet paper category since the early ‘60s. The Andrex puppy is an instantly recognisable symbol of the brand’s softness and strength. Commercials often show the puppy running off with the roll and extending it to great length – emphasising that it goes a long way.

These associations and memories, evoked and reinforced over 40-odd years, make it easier for people to remember Andrex and what it stands for (soft, strong and long). The message content is pretty much generic to toilet paper but Andrex has been highly successful in sales for many years. When I see Andrex on the shelf I notice it and I remember it’s the one with the playful puppy. The infamous ‘scrunch or fold’ campaign of last year, which broke with Andrex’s familiar approach, provoked a negative reaction for several reasons (and it now seems to have been removed from YouTube) but even that campaign was not so grievously misguided as to remove the puppy altogether.

The moral seems to be that you abandon your long-established brand associations at your peril, particularly if you replace them with an attempt to talk to people about how they wipe their arses.

I’m not suggesting it’s as simple as saying product messages won’t work, while emotions will work. Sharp says, “Brands largely compete in terms of mental and physical availability. This doesn’t mean that product features, and consumer evaluation, aren’t important – just that they operate within this battle for attention… so while positive features and perceptions help a brand to be chosen, they only do so when they are part of the selection set (i.e. after the buyer has culled most of the other brands). Over time, feature advantages can build salience; with time they assist in gaining mental and physical availability.”

As has been pointed out to me (by Sell! Sell! Blog http://www.sellsellblog.blogspot.co.uk/2014/05/how-advertising-works.html?m=1) this is probably exactly what’s happened with Andrex. What started as a product excellence claim (soft, strong, very long) has developed over time into a set of associations where the puppy represents Andrex, which stands for soft, strong loo roll.

Of course, there are some agencies who’d prefer to dispense with any kind of product message. And there are some advertisers who think they can rationally convince people of product superiority, without having to be moving or entertaining. Both extremes are probably wrong.

So, how does advertising *really* work?

According to Sharp’s research, to make your advertising effective, follow these guidelines:

– reach as many potential buyers as possible

– advertise continuously

– appeal to the emotions – be entertaining and interesting, so people don’t ignore you

– use distinctive and familiar brand assets that build and refresh memories and associations

– the inclusion of rationally persuasive facts won’t necessarily affect sales. If you have a piece of information that is genuinely persuasive, then say it, so long as it does not interfere with achieving the previous objectives.

Or, as we say at Wieden+Kennedy, move me, dude.
