7. Research Question
• Do search engine shopping ad characteristics influence consumers’
attention and choice?

8. Relevant Literature
• 12%-30% of searches are product search related (Broder 2002, Rose and Levinson 2004;
Spink and Jansen 2004)
• On SERP, sponsored links (SEM) are looked at, but organic results
generate more attention and clicks (Lo et al. 2014; Philips et al. 2013; Kobylanski, 2012; Buscher, Dumais,
and Cutrell 2010).

9. Relevant Literature
• Position on SERP
• Some SEM strategies work better than others in terms of attention and ROI
(Ghose et Yang 2009; Jansen et al. 2007; Shrestha, Owens, and Chaparro 2009; Agarwal, Hosanagar, and Smith 2011; Gisbergen,
2007).
• Brand Repetition
• On a SERP, a presence in both SEM and SEO results improves click probability (Blask et al. 2011;
Jansen and Mullen 2008; Danescu-Niculescu-Mizil et al. 2010).
• Attention and click on SERP
• Time spent looking at SERP elements is correlated with click probability (Buscher et al. 2010;
Huang et al., 2011).
• Product Ratings
• They do influence online behaviors (Duan et al. 2008, Chevalier and Mayzlin 2006, Dellarocas et al. 2007, Moe et
Trusov 2011).

11. Method
• 2 x 2 x 2 within-subject experimental design
• Task: Search on Google using assigned keywords (40 searches)
• Sample: 52 students
• IV:
• Shopping ad position (top left or right);
• Product reviews (presence or absence) and;
• Brand presence in SERP organic results (presence or absence).
• DV:
• Total fixation time on shopping ads (Tobii X60) and click
• Control:
• Adword presence (presence of absence), sig. for H1 and H3.
• Subjective knowledge (Flynn and Goldsmith 1999) about search engines, n.sig.
• Analysis: Linear Mixed Model (to account for repeated measures).

13. Step 1:
Enter assigned keywork (from the keyword list)
Repeated 40 times
Step2:
Click on the most interesting link

15. Contribution
• Investigation of shopping ad characteristics on consumers’ attention
and choice.

• Shopping ads are effective especially if they:
• Include consumers’ ratings
• For search engines
• Shopping ad are more effective when
• Positioned above organic results
• Accompanied by consumers’ reviews (importance of WOM)

17. Limitations and Research Avenues
• Lab setting;
• Keywords assigned to participants;
• Only investigated first click on SERP;
• Participants were somewhat heavy Internet and search engine users.
