Want Brand Authenticity? Be Authentic.

We don't know the name of the first brand. What we do know is that up a grassy mountainside a few millennia ago, a big Norse farmer was getting a bit annoyed about having his cows stolen. In a fit of Viking desperation, he started to burn his initials into his cows to stop them being nicked. Brandr, the Norse word for fire, became our operative verb. An industry that would dominate marketing was born not from the desire to differentiate or connect with consumers, but from the simple need to mark ownership and origin.

Unfortunately, a great number of British marketers operate under the mistaken impression that brands are built purely around consumers. This is partly true, but brands must also represent their origins. A brand is not a malleable product that can be moved willy-nilly around a perceptual map to follow consumer needs and drive sales. Brands are anchored in provenance, founders and heritage.

The Citroen C5 work is a case in point. A blond male whizzes around Germany in his car to the strains of Wagner. A German-accented voiceover describes the car as 'unmistakably German' before revealing it is a Citroen made in France. It's a smashing ad that agency Euro RSCG should take pride in. But it is entirely inappropriate for the brand, and Citroen should hang its head in shame.

This ad will drive awareness in the short term, but over the long term it will damage the brand associations of Citroen and leave it in no man's land. If consumers want German-made, there are several exceptional, authentically German brands. It is a message lost on Citroen's UK marketers - the way to build brand is to focus on Citroen, not your competitors.

An equally worrying picture is emerging at Diageo. Its leading gin brand, Gordon's, has responded to losses to stores' own-label products by spending the past year hitching its brand to celebrity chef Gordon Ramsay. The campaign shows a close-up of the chef's face next to the gin, accompanied by a bold statement in true Ramsay style. The inference is that this is his gin and comes with all the personality one expects from such a provenance.

Except, of course, it isn't Ramsay's gin at all. It's Alexander Gordon's gin, and was invented 200 years before Ramsay was born. There is enormous brand equity here. Gordon's has survived and prospered because it has something that makes it special. Diageo's challenge is to find out what this something is, define it and offer a contemporary execution of it. Don't just give up on a quarter of a millennium of heritage and hire a chef who is simultaneously endorsing about 400 other products, has nothing to do with your gin and will soon dim in the public consciousness.

Again, no shame should be attached to its agency, Bartle Bogle Hegarty, for creating these ads. It is an ad agency and, while most agencies will tell you that they are in the business of brands, they are, of course, in the completely different business of advertising. Ramsay will generate short-term awareness and arrest the brand's losses, but over the long term Diageo is eroding one of its most valuable brands with an inappropriate, short-term fix that will cause long-term damage to its brand equity.

Consumer-insight companies say consumers have started seeking 'authenticity'. That's rubbish. They always wanted it. Most consumers are a lot smarter and more genuine than the marketers who target them. They want brands burned with the mark of their founders, not artificially engineered by agencies. They want to know who made this brand, where and why. It's time for marketers to get back to the authentic meaning of brand.
