How to calculate the cost of good publicity - Step 1: find back of envelope
A few weeks ago I wrote a column in The Post casting doubt on claims that events in the city actually generate the money which they are purported to generate.
It was claimed, for example, that the Tory conference at the ICC would bring £20 million into the local economy. Still not noticed the boom in sales of Ferraris in the city? No, me neither.
I don't doubt that big events raise a company's/city's/person's media profile but I remain sceptical about the level of economic largesse.
My Deep-Throat in the city's PR community has confirmed my fears.
They claim that a well-known organisation calculates the value of media coverage thus:
1) Add up the number of column inches of coverage and which publications it appears in (including the web)
2) Find out the advertising rates per column inch for each publication.
3) Multiply the advertising rate per column inch with the number of inches of coverage achieved, to give the 'AVE' (Advertising Value Equivalent).
And here's the good bit:
4) Multiply the AVE by an arbitrary factor - say x3, but why not x10? - to give the "PR value" of the coverage achieved.
The joy of this is that it allows PR companies to charge fairly robust commission rates and scrummy bonuses.
Whether this methodology serves any purpose beyond feathering the nests of spin-doctors is another matter, however.
