At last, How Brands Grow part 2

The follow-up book, instructively titled 'How Brands Grow part 2' has been released, and after selling out (thanks to Oxford University Press and their conservative print runs) is now available from Amazon.

Associate Professor Jenni Romaniuk is my co-author, and we've been helped out by our colleagues in the Ehrenberg-Bass Institute.

The new book answers the questions people have asked about B2B and industrial markets, durables and services marketing, emerging markets, and luxury marketing. unknown

Critics and Misconceptions

The original version of How Brands Grow was published five years ago. Over that period critics have been very kind, it's been lovely to read so many glowing reviews. To be honest I've been surprised at the lack of criticism because the book doesn't pull its punches, it doesn't go out of its way to avoid making enemies. The sub-title "what marketers don't know" is deliberately provocative, and faults are exposed in market theories and marketing theorists (both academic and consultant).

Yet criticism has been muted. Most is along the lines of "yes I agree with a lot of what he says" – with the implication…. "but not all of it". Yet very few have been willing to say which bits they dispute. I suspect this is from fear of embarrassment because they don't have evidence to support their belief, it just feels wrong. Fair enough, many of the findings in 'How Brands Grow' are confronting, counter to current beliefs, counter to what was learned at university. Those feelings of scepticism are perfectly healthy, so long as they encourage further thinking and data gathering. If you don't believe me please try to prove me wrong – only good can come of it.

I expected people involved in the direct marketing industry to be upset as they had been highly enamoured with myths of loyalty, targeting and customer engagement, yet they largely seem to have accepted the evidence and embraced the need for broad reach and evidence-based results. The same for those working in online media, while there are still plenty of people preaching the need to build deep customer relationships those who have read How Brands Grow seem perfectly happy to switch towards building physical and mental availability in big heterogeneous mass markets.

What little criticism there has been 'How Brands Grow' has come from marketing consultants, mainly those selling market research products. Of course, there are financial reasons, 'How Brands Grow' exposes that some of the things they say are essential to measure aren't very important. In some cases it exposes that their special proprietary metrics are equivalent to snake oil cures. There is also loss of pride, several have come out with critiques that are more along the lines of "it's not right, but if it is then I knew it all long ago".

Here are a couple of the things that have been said that are worth refuting:

Double Jeopardy says that brands can't grow – wrong. Actually, the whole book is about brand growth. The fact that brand metrics follow the DJ law tells us what will happen when a brand grows (i.e. how those metrics will change), it does not say that brands can't grow.

Double Jeopardy means there is no loyalty – wrong. Double Jeopardy clearly shows that loyalty metrics are predictable. In doing so it also shows that all brands get loyalty, that loyalty is everywhere. It just isn't the 'brand love' style loyalty that so many consultants love. Consumers are polygamously loyal.

Branding and Mental Availability - the distinction

A brand needs to build relevant memory structures that make it easier to notice, recognise, recall and hence.... of course...buy. This is the brand’s mental availability.

Branding helps build mental availability, it’s like a coat-hanger on which memories can hang.  It’s like a Dewey decimal number which tells the brain’s librarian which memories to access and/or refresh.

The branding in itself rarely communicates anything else, nor does it need to. McDonald's scottish name is a brand, it communicates nothing about usage situations, food types etc - no haggis served at McDonalds.

Branding is branding - full stop.

So what memory structures does a brand need? This is a useful question to ask when launching a new brand (and this example is a good reminder for existing brands too).  

Launching new brands is very risky, it's very easy for things to go wrong.  The question a marketer needs to ask is "what are the CRUCIAL memory structures that I need to get into as many heads as possible?".  In other words,
what memories, if they were missing would massively reduce the chance of purchase?  These usually turn out to be rather prosaic (and hence easily missed by those marketers who don't tend to be the most down-to-earth people)... things like…. what does the brand do (e.g. it is a car), what does the pack look like, where is it likely to be found, where will it be used/bought, who will buy it and so on.

If this sounds too simple then how come so many marketing campaigns seem to neglect this?

Share of wallet is not the key to growth - a loyalty myth

I was surprised and disappointed to see that the authors of the book “Loyalty Myths”, TIm Keiningham et al, themselves promote an old loyalty myth in the latest Harvard Business Review (Oct 2011).

The article reports a "discovery" of a relationship between verbal attitude reports and Share of Wallet/Purchases (measured in a period of panel data).  This is re-discovered every so often, indeed Jan Hofmeyr even won an award for it a few years ago.  This re-discovering (and misinterpretation) over and over says a lot about the sad state of our discipline given that the relationship was very well documented in the 1960s by Bird, Channon, and Ehrenberg (see references below).

Like Hofmeyr & colleagues (2008) the HBR team have done a rank order correlation which, in this case, guarantees high correlations of around 0.9.  Correlation is not a good way of assessing predictive ability (which I
illustrate here). Yet they report that their analysis is “to our knowledge the largest and most rigorous of its kind”.

The article goes on to imply that great financial returns can be gained from improving loyalty of existing customers.  They recommend that managers move from a focus on the drivers of satisfaction to focus on share of wallet rank. This takes a leaf out of Reichheld’s book, when he said forget about satisfaction and focus on willingness to recommend (Net Promoter Score). In this case it’s true that larger market share brands do have higher share of wallet rank. What they fail to mention is that such loyalty metrics move only a little, and do so when a brand's penetration increases dramatically –
the Double Jeopardy law.  

In effect they rely on an old “wouldn’t it be great” argument that goes along the lines of “if those customers who give us very little of their spending became near 100% loyal, then we'd earn X more money”. It’s like saying “if you win the lottery then you’ll be richer”, all logically/analytically/theoretically true but it’s easy to make theoretical statements that clash with the empirical world, as this does.  It's all beautifully academic, but not scientific nor practical. It’s not how brands grow.

Note how costs are also conveniently ignored. In the same way that Reichheld ignored them when promoting his
retention and profitability myth.

The authors recommend finding out the motivational reasons why people give only a small amount of their spending to your brand and lots to others. But this ignores the weak link between claimed motivations and behaviour.

In the article they present a grocery store as an (fictional, hypothetical) example - why they didn’t (couldn’t?) show a real case is rather telling.  In their hypothetical example the store drops prices on staple items to encourage low share of wallet customers to give them more of their supermarket shopping trips. Now supermarket repertoires have what is called high "1st store loyalty", in that the top store in anyone's repertoire tends to dominate, with the remainder of their repertoire being divided amongst several others.  From the store's perspective then, it has a large group of customers who are very loyal in the sense that they do most of their grocery shopping there.  And then another group of customers who largely do their shopping at another store.  The former group tend to live close by, the latter further away (a fact that is ignored in the article).

So TIm Keiningham & co are on sound ground in recommending a focus on the people with low SCR - sales growth does indeed largely come from the latter group (since obviously it's hard to get more out of people who already give you nearly all their custom).  But the real story for growth is, target your light and non-customers.  Go for reach.  Increase your mental and physical availability (e.g. open longer hours, open another store, make it easier for people to shop and shop faster...).

That's a very different story than the old-fashioned loyalty one (re)presented in the HBR article.  And the promise of riches to be gained from a share of wallet focus…..that’s a chimera.

Millward Brown replication - successful brands have low perceived differentiation

Almost all successful brands have very low perceived differentiation, yet they have loyal customers, they earn profits, and many of them have done so for many decades.

Is digital media the new price promotion

Is digital media the new price promotion ?
I just heard a marketing mix modeller say that every project he has done in recent years has resulted in the conclusion that the advertiser should move some money out of TV and into digital (i.e. banner ads, social media).
Now marketing mix modellers have been telling clients similar (brand damaging) things for a long while about price promotions, i.e. take money out of TV and spend it in-store. Is this another chapter?

People don't like changing their beliefs

I like this quote (we all know some poor academics and consultants who rely on this phenomenon):

"It is more comfortable to have one’s existing beliefs and skills reinforced.......students give high ratings to outside speakers who tell them to rely on their gut instincts because techniques taught in school are of no value in the real world"


From J.Scott Armstrong (1998) “Are Student Ratings of Instruction Useful?” American Psychologist, vol. 53, p.1223-1224

Mental Availability is not awareness

A brand's mental availability refers to the probability that a buyer will notice, recognize and/or think of a brand in buying situations.  It depends on the quality and quantity of memory structures related to the brand.  See chapter 12 of "How Brands Grow". Read More...

How did they do it?

Innovation to avoid differentiation

Emotional versus Rational Advertising

On page 134, table 9.1 of "How Brands Grow" I write that rather than saying thinking is emotional OR rational we should realise that most thinking is emotional And rational.

I question the value of the emotional rational dichotomy.  It's based on an out-dated view of emotions, and thinking.

Do viewers pay less attention to emotive advertising, and does it matter?

For advertising to work consumers have to notice it.  And the more processing they do the better, though for an awful lot of advertising very little processing is needed – it’s only advertising after all, the message is very simple, and this is particularly true for emotion oriented advertising – whereas persuasive, information oriented advertising suffers from the requirement to gain a degree of processing including rational  conscious processing.

In the latest issue of the Journal of Advertising Research there is a characteristically interesting article by Robert Heath (with colleagues Agnes Nairn and Paul Bottomley).  It somewhat controversially shows that viewers pay slightly less, not more, ‘attention’ to emotion oriented (as opposed to rational persuasion oriented) TV commercials.  The authors (who are huge fans of emotion-oriented advertising) speculate that perhaps emotion oriented ads work by inducing less rational thinking and hence stimulate fewer counter arguments – I think such an effect would be trivial, there is a much more simple plausible explanation of how and why emotion oriented ads work.
