Stop pretending PR is worth the same as advertising space

In this guest posting, Millward Brown’s Sarah Emerson says the old-fashioned PR formula of adding up column inches and equating it to what the ad space would have cost needs to be killed off.

Last Sunday’s ‘Crave Sydney’ Breakfast on the Bridge event in Sydney was supposedly worth up to “$10 million in overseas publicity” according to media reports quoting the NSW Premier Nathan Rees.    To use a tourism turn of phrase, ‘where the bloody hell’ do these numbers come from?

The continuing use of advertising value equivalents (AVEs) to predict and measure non-paid for media exposure and tout the results as a definitive measure of success is frustrating. There are many, at best shortcomings, at worst fundamental flaws, with the creation of an “advertising value equivalent”.

Traditional AVE creation utilises a straight multiplier of full page rate to percentage of page. As a result, small appearances generate very little value which means they don’t acknowledge the achievement of getting publicity and reaching your audience in the first place, whereas multipage items overwhelm all other achievements – even if the coverage is neither favourable nor on message.
