Does hyperbole works in advertising?
The kind that can't easily be verified - "the best", "the greatest", "the nation's favourite" etc?
Yes. I can only speak from my area of experience which is video (I'm in video production and create vids to help customers sell more and see hyperbole work). I my opinion, there are three types:
1. On the gullible. I worked on one of the most successful advertising campaigns in British history. Frankly, I'm embarrassed although I was only brought in to video a tiny part at the last minute. The people running the campaign were openly saying they were targeting people who were gullible and less than intelligent. However, the people running the campaign were also extremely intelligent, absolutely merciless, had really defined their target markets, understood what it would take to get their message to their targets and knew it would work. It was brilliant and a real, learning curve for me.
2. Strong brand statements. These, for me, are also hyperbole. Nike, for example, trades off their incredible branding. However, they're just selling T-shirts and trainers. Will their trainers make me run faster? Well, no. But they can change twice as much due to outstanding, hyperbolic video branding:
3. Where hyperbole meets humour. I love these:
So yes, hyperbole works and it's mainly a question of defining target markets. Some people buy into it and I have personal experience working on campaigns where it's worked.
