What would have been considered daring and adventurous marketing a couple of years ago now seems slightly passé, now that every Tom, Dick and Harry is trying to jump on the guerrilla bandwagon.

Which makes me happy that I’ve worked in house with the acknowledged masters of stunt, Cunning many times over the years. You’ll probably remember their projection of Gail Porter on the side of the House of Commons.

I believe guerrilla marketing is like comedy – if something seems not quite right, it makes the whole thing completely wrong. Which is probably why so many companies attempt it but don’t succeed. Last year I saw a group of promotional people pretending to be ‘aliens’. Dressed in green leotards they walked around Soho Square picking out who they assumed were homosexuals to give them laundry detergent samples. For fucks sake.

For me, the point of guerrilla marketing is to make an impact on media-savvy, cynical bright young things who usually have a distinct sense of humour. It has be ‘different’ and designed so that people actually enjoy the fact that they’re being marketed to.

Many brands are not suitable to be promoted by guerrilla marketing. And for some big corporates keen to play it safe, the original idea becomes so diluted that it’s so far from the original concept that it’s safest not to do it. YOU KNOW WHO YOU ARE.

Effective guerrilla tactics need to be well thought out. Don’t risk mimicking anything that has been done before, and don’t leave it in the hands of non-specialists. Do it badly and you lose an audience, your brand loses credibility and the only question on people’s lips will be ‘who in God’s name did that?’. Trust me.
