So we are paying a CPM of around $75 for this advertising. That's really expensive.
I'm not saying these audio spots are a bad idea, I don't know. I'm saying $20K is a LOT of real money for an advertising budget.
If we are ready to spend that kind of cash, we should consider print ads in Bitcoin Magazine.
For $20K we could get full page color ads on page 1 for the next three years in a printing of 25,000 in each month's production run.http://bitcoinmagazine.com/advertising/http://btcmag.9wizards.netdna-cdn.com/wp-content/uploads/2013/12/BITCOIN-Pricing-List-Interactive-Issues-17-19_web.pdfThis would have a CPM of around $20-$25. Don Draper of Mad Men would say that's three times more effective.
Plus every ad could have a QR code or URL that would sweep the user immediately on to more info.
