Purpose: Extant research on comparative advertising has focused only on “market leader” comparisons (a brand targeting the market leader), whereas in the marketplace, “multi-brand” comparisons are more prevalent (Kalro et al., 2010). Moreover, most research focuses on direct comparisons only. Hence, this research aims to investigate the interplay between comparison ad strategy (“market leader”/“multi-brand” comparisons) and comparison ad format (direct/indirect comparisons) on the effectiveness of comparative advertising. Design/methodology/approach: This paper uses four 2 × 2 fully crossed factorial designs (comparison ad format: direct vs indirect and comparison ad strategy: market leader vs multi brand) with established and new brands in two categories: powdered detergents and smart phones. All studies were conducted in metropolitan cities of India. Findings: By and large, the experiments indicated that direct (indirect) comparisons lowered (heightened) perceived manipulative intent and enhanced (reduced) attitude-toward-the-ad for multi-brand (market leader) comparisons. Practical implications: Findings suggest that when advertisers use comparative advertising, they may use direct ads when using multi-brand comparisons and use indirect ones when using market leader comparisons. It could also be argued that when advertisers use multi-brand comparisons because of fragmentation in the marketplace, they may directly compare against these multiple brands. When advertisers need to compare against a market leader, they may do so indirectly. Originality/value: This research is among the first to investigate multi-brand comparisons that are widely used in the industry and that too in the context of both direct and indirect comparison formats.

Comparative advertising is widely used as a persuasion tool. Contemporary advertisers employ both direct (e.g. "Total Corn Flakes have more nutritional ingredients than Kellogg Corn Flakes") and indirect comparative advertisements (e.g. "Total Corn Flakes have more nutritional ingredients than other corn flakes") in their campaigns. Consumers process ads predominantly either through analytical (using reason and semantics) or imagery (using nonverbal, sensory representation of perceptual information) modes of processing. Drawing on extant research in advertising and information processing, we posit that direct comparisons are better suited for analytical processing while indirect ones are more amenable for imagery processing. Using a 2*2 factorial design (comparison format-direct/indirect; mode of information processing-analytical/imagery), we show that direct (indirect) comparative advertisements are more effective in reducing perceived manipulative intent, enhancing attitude toward the advertisement, and increasing the perceived differences between the brands for consumers using analytical (imagery) information processing modes. We add to the comparative advertising literature by identifying a moderator (mode of information processing) that influences the effectiveness of direct and indirect comparisons. Further, we study indirect comparisons when most extant research considers direct comparisons. Managerially, our work suggests that advertisers using comparative advertising should use direct comparisons under analytical processing conditions and use indirect comparisons under imagery processing conditions. © 2013 John Wiley & Sons, Ltd.

We conducted a content analysis on 203 comparative print advertisements in India. We found that as hypothesized, direct comparative advertisements were used more (vis-à-vis indirect ones), differentiative claims were used more (vis-à-vis associative ones), maximal claims were higher than minimal claims, multibrand comparisons were greater in number (vis-à-vis single-brand comparisons), positive valence is preferred to negative valence, and underdog brands used more comparative advertisements than top-dog brands. Contrary to expectations, we found that hedonic and utilitarian products used comparative advertisements equally. We offer a snapshot of the state of comparative advertisements in India that would be useful to managers and researchers. © Taylor & Francis Group, LLC.
