RT Journal Article SR Electronic T1 The Impact of Trademarks and Advertisement Size on Yellow Page Call Rates JF Journal of Advertising Research JO J Advert Res FD WARC SP 119 OP 125 DO 10.1017/S002184990404005X VO 44 IS 1 A1 Abernethy, Avery N. A1 Laband, David N. YR 2004 UL http://www.journalofadvertisingresearch.com/content/44/1/119.abstract AB Split book yellow page tests randomly distribute different versions of the test advertisement in the same market at the same point in time allowing direct assessment of the customer pulling power of different sizes or types of yellow pages advertisements. Using the results from 78 split book tests, we find that including trademarks in small in-column yellow page advertisements can have a very strong influence on call rates. Partially confirming previous work, we also find that larger advertisements do generate more calls than smaller advertisements. However, the increase in call rates is not a straight line relationship.
