You don't need high ratings (or any ratings) to sell spots.. A good salesman can sell spots to anyone in any market.
They are called superstar salespeople because they
1. Know how to counter any objection
2. The know how to maintain the client
3. They know how to so a ROI from the spots.. (which is word of mouth, the customer controls).
Sadly, there a so few that can do this.. most are order takers and would starve in a smaller marker or a station with low or no ratings.
Just because you have low PPM numbers, doesn't mean crap. If you have an audience , you can sell it.
All of that is true, but to an extent.
Here are the problems:
75% of the commercial station listening in the Inland Empire market is to LA stations.
The metro for Nielsen is 26th in population but 48th in revenue among all radio markets.
Most agencies use LA stations to cover their needs in that market.
Many agencies, and more every year, are using automated buying with no transactional conversations or meetings. A low rated station will not be able to get on any of those buys.
Local retail business is limited as the market is a "bunch of adjacent cities" that are not really a community. Small local retail businesses pay small rates.
Much of the population works in the LA MSA, so they will be consumers in both markets.
I agree that ratings are only part of it. But that station averages only about 900 25-54 persons in its whole coverage area, so the chances of a spot hitting a potential consumer are pretty limited.
And the biggest factor is cost. To the advertiser, reaching 900 people with each spot means the rate should be just a couple of dollars a holler. To the station, that is not enough to cover expenses in what is a very expensive state and metro area.
There is a point where even a great seller can not extract blood from a stone. And, yeah, I have a lot of sales experience myself.
