"What does my audience cost?"
Don't confuse the lowest spot price with the best deal.
Your
own Target Audience CPM is the daypart spot cost divided by the number of
TAs listening, in thousands. (See example above.)
Most
stations work hard to attract and hold a loyal audience. They tailor
their formats to fit the interests of the main DEMOS: Persons aged 18-25, 25-34, 35-44, 45-54, and 54+. Males and Females.
You want to buy those stations that reach your "Target Demo" the best. Ask any rep to run a
"Cume Ranker" on your audience. You'll get a list of all stations ranked by the size of their
TA Cume (weekly cumulative audience). If
you add up all the cumes of all the stations in town, the total radio
audience is usually about 2.4 to 3.1 times the total population. Most
people listen to three stations.
You can also ask for certain demographic qualifiers, such as
education level, homeownership, children under 5, etc. Caution: the more qualifications you put on a query, the fewer Arbitron diary-keepers will comply, and the fuzzier the projected ratings.
"What's a Grip?"
One
GRP or Gross Rating Point means, "A
number of impressions equal to 1% of the market's Target Audience."
If there are 1,000,000 Persons
25+ in a market, one GRP
equals 10,000 impressions among Persons 25+. That could be one spot
reaching all 10,000 at once, or two spots reaching 5,000 each, or eight spots reaching 1,250 each, or any other combination adding up to 10,000
GIMPS or "Gross Impressions".
REACH X
FREQUENCY = GRPS
If you reach 70% of the population 3 times, you've
bought 70 x 3 = 210 GRPs. Two hundred GRPs a week is a reasonable media weight for a sustaining campaign in a total market.
Brand Intros need more tonnage up front. If your main competitors each
run 300 points a week, you probably won't beat them with 75.

POP QUIZ: There are
595,340 P12+ in a market. The competitive P12+ CPM is $5.85. Assume all stations in town charge competitive and fair rates(!). Your Target Audience is Females 25-44. There are 126,500 of them in the market. You want to buy exactly
200 Target GRPs.

Direct Response advertisers usually ignore GRPs.
DR advertising has to achieve an acceptable Media Cost Per Sale which is a
function of response rate, CPM and conversion. The dynamic
relationship between those variables is covered in GM/C=X v CICO.

Is Radio Cheaper than TV? Radio delivers high frequency against narrow cumes over time. TV can reach a broad audience fast. A general rule of thumb is that in any local market: 100 Radio :60 GRPs cost about half as much as 100 TV :30 GRPs.
Is Radio Cheaper than Newspaper?
Newspaper rates are based on total circulation and ad size. Car Dealers run huge, nearly identical ads in the weekend Automotive
section, pay dearly, and get mostly Highly Qualified Active Shoppers. If your TA is over 40 and you have some sort of a deal to offer, newspaper is usually pretty effective
but fairly expensive unless you buy huge annual contracts.
Is Radio Cheaper than Outdoor? Billboards hit everyone. Rates are based on monthly traffic past each location. If you can squeeze your message into 32 letters, outdoor is a great medium. Radio +
Billboards = "The Poor Man's Television." People whiz by
your Thing while your Jingle plays on WIYU.
"How many spots should I buy?"
A precise answer to
that question requires a creative test, preferably on the local station that
boasts your highest TA or QA (Qualified
Audience) cume. If you can track daily response
(calls, clicks, store traffic...) you can determine your own
Optimum Effective Frequency in a few weeks, then
use OES (see below) to pinpoint future buys.
Optimum Effective Scheduling
Several years ago, Arbitron came up with the OES Formula that helps you get an excellent combination of reach and frequency on any one station. Here's how it works:
-
Cume/AQH = Δ. ("Turnover" is the number of times the AQH has to refresh itself to add up to the weekly cume.)
-
Multiply target Optimum Effective
Frequency (OEF)
by 1.1. (3 x 1.1 = 3.3).
-
Multiply by Δ
and round up to the nearest integer. Buy that many spots a week in the
selected daypart, ideally at ROS rates.
-
You will reach half or more of the cume
f or more times.

Arbitron thought all buys should be
ROS (run of station), ideally Monday 6a
to Sunday 12M.
The problem with that idea is that the entire week includes a lot of
overnight "quarter hours" when few people are listening. Those
overnights reduce overall AQH in
the Cume/AQH equation which increases Turnover itself, and leads you buy too
many spots that beat dead air.
I prefer to use OES to plan
ROS runs in broad day parts, such as Mon-Fri 6a-8p. I'll reach 80% to 90% of
a station's P1s at a significant savings compared to Fixed Position buys.
"What about Network Radio?"
Large wired networks such as Premiere and ABC
feed hundreds of stations daily programming (such as Rush Limbaugh or top-of-the-hour news feeds) with built-in spots. You buy a national audience at much higher per spot costs, but often at half to a quarter the cost per thousand compared to local spot rates.
See Network Rollout for more.

"Can I run
an infomercial on radio?"
Yes! Many AM stations sell half-hour or hour-long segments, usually on Saturdays and Sundays
when audiences are sparse. A long-running program can build its own
tune-in audience, though. Don't pay more than 12X the FP :60 rate for an
hour! There's a new move to allow advertisers to webcast their programs from links on the station's web pages. (For example, WMAL-AM in
Washington, DC. will sell you a 15-minute "commercial" that runs only from their web page on weekends.)
"How do I get lower rates?"
I can't give away all my secrets, but here are a few general principles. Some seem contradictory, but they all work.
Buy Early.
If you can negotiate with a station two or three months early, way before they're sold out, you can often get much better deals, especially if a station has taken a ratings hit in the last Arbitron.
Buy Late.
Sometimes big national or local advertisers will pull out of a station at the last minute. If the reps know you are willing to deal - at the last minute - you can often get great opportunistic buys.
Mix Fixed with ROS.
To get a good combination of reach against weekly cume AND frequency AND price, you should let your rep place 20%
to 25% of your budget in available, lower demand, holes in the weekly line-up.
Avoid remnant spots
unless you are in absolutely no hurry to increase sales. Remnant spots
are cheap because nobody listens to them.
Start in January!
After Christmas, local retailers take a breather, demand drops and so do prices. Knowing this, stations often put special packages together - 20 to 40 spots a week at 30% to 40% off rack rates. You can often book up to 13 weeks in a row at these prices.
Make Owners Compete.
During the past decade, most local stations have been bought up by Clear Channel, Infinity, Beasley, Cox etc. When two or more holding companies own several stations that reach your audience, you can often get the reps to compete for your entire budget - if you promise to place it all on their stations. (Use this technique
sparingly, though.)
Buy A Lot.
Radio time is somewhat of a commodity. The more quantity you buy, the better deals you'll get. It's usually better to ask for extra spots, or promos, or :10 IDs than for lower prices, though. A $10,000 a week schedule on a station for four weeks or so ought to get you at least $500 worth
of freebies.
"What about Creative and Production?"
A good radio spot costs much less to write and produce than a
good TV spot. A good spot run
nine times will out-pull a mediocre spot run ten times. Standing out
works better than blending in even if you sell an absolutely
generic commodity.
If you
want to
write your own copy, read it
yourself, too! You'll sound more credible than the station's basso
profundo throaty voiced announcer. Plus, your friends will all say,
"Hey, I heard you on the radio!" Fame
& Fortune Mitigate Stage Fright.
If you use a local Production
company or studio, they may bundle the costs of creative, studio, talent and
music into one fixed price. I estimate the
Costs of Radio Production and
test media budgets all at once, and in some detail.
