Do Display Ads Influence Search? Attribution and Dynamics in Online Advertising
The introduction of online metrics such as click through rate (CTR) and cost per acquisition (CPA) by Google and other online advertisers has made it easy for marketing managers to justify their online ad spending in comparison to the budgets used for television and other media. However, these metrics suffer from two fundamental problems: (a) they do not account for attribution, since they give credit to the last click and ignore the impact of other ad formats that may have helped a consumer move down the conversion funnel, and (b) they ignore the dynamics, since they only account for the immediate impact of ads. As firms spend more of their ad dollars on online search and display, managers and researchers alike recognize a need for more careful attribution adjustment that takes into account the journey consumers follow before conversion as well as account for the impact of ads over time. In this paper, the authors use time series models to infer the interaction between search and display ads and also capture their impact over time. Examining data from a bank that used online advertising to acquire new customers for its checking account, the authors found that display ads have a significant impact on search applications, as well as clicks. The majority of this spillover was not instant, but took effect only after two weeks. On the other hand, search advertising did not lead to an increase in display applications. However, search ads showed significant dynamic effects on search applications that made them very cost effective in the long run. Key concepts include: Classic metrics used in practice are highly biased since they do not account for the effects documented in this study. As a result, firms may be making suboptimal budget allocation decisions. Managers should carefully consider the interaction and dynamic effects of search and display advertising. In the study, revised measures of ad effectiveness lead to a very different budget allocation than the one used currently by the firm. Even though the proposed allocation gives credit to display due to its effect on search applications, the search ad budget should be increased by 36% from its current level due to its strong dynamic effects. The display ad budget should be decreased by 31%. Closed for comment; 0 Comment(s) posted.

Social Network Marketing: What Works?
Purchase decisions are influenced differently in social networks than in the brick-and-mortar world, says Harvard Business School professor Sunil Gupta. The key: Marketers should tap into the networking aspect of sites such as Facebook. Key concepts include: Some social network users are influenced by the purchases of their friends. Of these users, 40 percent show a strong "keeping up with the Joneses" behavior, increasing sales by 5 percent. "High-status" users are more likely to not purchase something that others have bought. On social networks, viral campaigns may work better than advertising. Closed for comment; 0 Comment(s) posted.
