Information Content and Consumer Readership of Print Ads: A Comparison of Search and Experience Products

Abstract

This study builds on past research involving the economics of advertising information (Nelson 1970, 1974) to examine the interplay between advertisers' provision and consumers' readership of information. The authors focus on the prepurchase verifiability of advertising claims in three product categories: search products, experience shopping products, and experience convenience products. They use a broader measure of the information content of advertising than in past research, together with Starch readership scores for a sample of ads from nine U.S. magazines. The results show that the relationship between information provision and readership is positive for search products, negative for convenience products, and nonsignificant for shopping products. Average information levels are significantly higher in ads for shopping products than for convenience and search products. These findings suggest that advertisers may be underinforming consumers when promoting search products.
