Circulation Alone Doesn't Give Dentistry Journal Advertisers
the Full Picture, New PERQ/HCI Study Reports

NEW YORK (May 21, 2003) – PERQ/HCI has released the 2003 editions of FOCUS™ and Media-Chek®/APEX™ Dentistry Journal Readership studies. These studies provide dental publishers, manufacturers and advertising agencies with decision-critical information that goes beyond circulation figures to accurately predict the average issue readership and average issue ad exposure in professional journals among the universe of over 157,000 dentists.

The distinction between the number of recipients a publication is delivered to (circulation), and what the audience actually does with the publications they receive (readership), has been the basis for PERQ/HCI's readership methodology for over 30 years. Kathleen Henderson, Senior Vice President for Sales and Marketing, explains: "Too often, advertisers rely solely on the stated circulation of professional journals to choose where to place ads. Dentists and dental hygienists are busy, and may not take the time to read every journal they receive. They receive so many; they might not even realize they are receiving a particular title."

Henderson points to the 2003 data to support this claim: "The average received rate among professional dental journals is only 91%. These are journals that circulate to the entire universe of dentists, meaning that 9% of dentists do not even know they receive the journal." On average among surveyed dental journals, another 10% of those who report receiving a journal say they never read it. The percentage of journal receivers who actually read an issue of the journal ranges between 81% and 97%.

"Circulation is important, but not the whole story," Henderson adds. "It does not guarantee a comparable number of readers. As an advertiser, what you really care about is how many dental professionals are going to get your message." An average of only 37% of those who receive a journal are likely to actually see an advertisement in that journal. The range goes from 54% for the strongest journal down to only 22% of receivers seeing an ad in the lowest ranked publication.

A sampling of data from the report, along with additional helpful information for effectively advertising in the dental marketplace will be made available in the forthcoming "Guide to Effective Dentistry Journal Advertising" from PERQ/HCI. Additional details will be made available later this month at www.PERQ-HCI.com/dentistry.
