We've just launched a report, called 'Selling it Straight', on how it is better to err on the side of straight-talking and clarity in sales and other communications, than to take risks with fancy ideas. You've either spent too much money to now just throw away the opportunity through failing to get across some overly clever concepts, or your audience deserves more respect than to have you experimenting with language and form. Keep it simple and follow some basic rules (Grab. Hold. Harmonise. Inspire.) and you will maximise the effects of your message.
