Direct Response print and radio are
similar, but they work differently. Magazines and radio
stations both tend to attract loyal subscribers
and listeners. People do spend more time listening than
reading. But the two main differences that affect your Media Cost Per Sale
are
Frequency & Timing.
First, magazine readers don't have to read your ad again and again to decide,
"OK!" or "Maybe, some day..." or "Not for me!"
Many radio listeners do
have to hear your commercial 1,2,3...n times before they
make a decision. Frequency can easily build response in radio, up to a
point. Later on you'll learn how to determine your own Optimum Frequency
Range.
Second, magazine readers can scan your ad
at any time day or night. That copy of TIME or
ELLE
might sit on the table for days, weeks, even months, before a subscriber flips
through it. Most radio is consumed between 6am and 8pm Monday through
Friday.
Some people may be
willing to call you on a cell phone from their cars, but most
prefer to call when they're off the road. Click-to response has to occur
in front of a computer (Mobi notwithstanding). So...Lunch!
Historically, the best DR Radio time slot has
been 11am to 1pm. That
narrow range is broader today, but the underlying principles still apply.
People will call or click when it's convenient for them.
Radio pricing is based on the number of people listening
at any given time. Fortunately, most radio
stations charge less for the mid-day (10a-3p) slot because fewer people
listen then than during morning or afternoon Drive Time. Nights and weekends deliver even smaller audiences.
That's good for you. In general, DR Radio works best in those time periods
that big agencies don't want.
Since frequency and timing can both affect your MCPS,
you have to manage and track both dynamics very carefully. As
we're about to see, you'll need measurement tools that are a little
more robust than just comparing Cash In to Cash Out.
