Comparative analysis of advertising attention to Facebook social network: Evidence from eye-movement data
Introduction
Social networks has enjoyed a surge in popularity worldwide in recent years. Among the social networking platforms, Facebook has risen at the fastest pace. According to data compiled by Astralweb in 2015, 56.5% of American citizens use Facebook and an average of 450 million Asians use Facebook each month. In addition, statistics from the market survey firm comScore showed that the time Americans spent on Facebook exceeded Google for the first time (Anderson, 2010). From this data, it is evident that most Internet users today spend their time on Facebook, sharing recent developments, uploading photos or playing games. Clearly, Facebook has become a core part of people's daily routine even replacing information search as the most common purpose of Internet use. Thus, lots of renowned companies quickly realized the value of brand promotion by using Facebook, such as Coca-Cola, Samsung Mobile, Starbucks, Nike Football, Pringles, and so on. From marketing campaigns by leveraging Facebook's features, it creates a platform which satisfies marketers' needs to build interaction with customers and opens a transparent circumstance where information can flow freely between consumers and marketers. (Dunay & Krueger, 2010). Besides that, Vahl (2011) highlighted the businesses magnetism towards Facebook and mentioned that Facebook revenue from businesses advertisements reached approximately US$2.5 billion in 2011.
This flourishing Internet-based commercial activity is different from previous traditional consumer markets in that it does not possess human and interactive mechanisms. This has made Internet media an extremely effective marketing and advertising channel (Wang, Wang, & Farn, 2009). However, there is still only a limited and fragmentary understanding on how to utilize Internet advertising effectively. Zhang and Kim (2008) believed that there are four main factors behind Internet advertising usage: viewers, Internet advertising, advertisers and the advertised products or services.
Owing to desktop computer features, Facebook advertising placement options include right-hand side (RHS) ads and desktop news feed (DNF) ads. RHS ads appear on the bar located on the right side of Facebook, sandwiched between news feed and ticker. Benefits of placing ads on the RHS are because RHS ads are smaller and appear off to the side rather than front and center on the screen, RHS ads are less invasive. If advertisers choose to place their ads on Facebook's desktop news feed, ads will appear on news feed, the section of Facebook where posts by friends and family appear. It's important to remember, however, that placing ads on DNF means the ads will only appear on news feeds accessed through desktop devices or laptops. Benefits of placing ads on DNF are that consumers favor DNF ads because their resemblance to regular posts makes them more appealing to Facebook users. According to consumer surveys, people hate intrusive ads, such as pop-up ads and video ads that play automatically with sound on. On the contrary, DNF ads blend with its environment and do not interrupt the user experience. Although Facebook offers the two ads placement on desktop computers, it is necessary to have a more realistic understanding of how, how often, and what consumers have read on Facebook ads while browsing Facebook page. Therefore, how to effectively attract viewers to the Internet advertising placed on social networking sites is one of the issues that advertisers are concerned about.
In the past, measurement of Internet advertising was based on Cost Per Impression (CPM) (Novak & Hoffman, 2000) but relatively quickly click-through rate (CTR) became the standard measure. The purpose of click-through rates was to measure the ratio of clicks to impressions of an Internet advertising (Dréze & Hussherr, 2003). Unfortunately, CTRs were plummeting in the real world because of four critical questions as follows: (1) why do banner ads seem to be ineffective; (2) what can advertisers do to improve their effectiveness; (3) does an immediate measure such as click-through rate undervalue online advertising; and (4) are memory-based measures such as recall or awareness more appropriate? (Briggs & Hollis, 1997). Therefore, no consensus can be reached about effective advertising transmission from this information. In other words, by considering the basic question of whether viewers are attracted to advertising on social network platforms, the measurement standard should be how much attention an advertisement receives. Although attention effectiveness has caught enormous concern in marketing (Hernández-Méndez & Muñoz-Leiva, 2015), it is difficult to understand an impact on consumers' decisions and emotion using CTR measurement. In recent years, researchers have been using eye tracking technology to examine the cognitive processing in reading, visual perception, and information processing (Rayner, 1998) and paid attention to advertising to make up for deficiencies in past research (Chung et al., 2013, Radach et al., 2003), even predicted the traditional advertising effectiveness for video advertising (Zhang & Yuan, 2018). In addition, Wedel and Pieters (2008) regarded the use of eye tracking as to obtain the viewers' visual attention which information enters to reach higher-order cognitive processes of increased interest. In order to address the above-mentioned questions about CRTs, eye tracking technology can be used to understand visual attention distribution by analyzing the viewers’ eye movement data and how attention changes from the eye movement paths. Therefore, to meticulously probe the level of attention given to Internet advertising makes it an extremely persuasive form of measurement.
Recent studies have used eye trackers to examine visual behavior of consumers, such as visual behavior on advertisements (Ju and Johnson, 2010, Pieters et al., 1999, Wedel and Pieters, 2000, Wedel and Pieters, 2008). By using eye trackers, digital advancement has improved the precision and usability. Throughout the history of eye tracking technology, researchers often define regions of interest (ROIs) to reveal how attention is allocated according to research questions and main areas of concern before the experiment to observe the relationship between eye movement variables and the main areas of interest of the experiment (Ho, 2014). Depending on the defined ROIs, several key variables have emerged as significant indicators of visual behaviors, including fixations, saccades, pupil dilation, and scan path (Rayner, 1998). Based on these key variables, this study adopted three kinds of dependent variables for processing eye movement data used in visual behavior observations, which are the total fixation durations (TFD), the number of fixations (NOF), and the latency of first fixation (LFF) on each ROI used to assess participants’ attention distribution. These data were related to endogenous and exogenous attention controls. The longer the TFD, the more attractive the ROI is to the participant; the larger the NOF, the more attractive the ROI is to the participant; the shorter the LFF paid on an ROI, the more attractive it is to the participant (Calvo and Lang, 2004, Hewig et al., 2008, Ho, 2014).
The main purpose of this study was to determine whether participants with different interpersonal relationships within Facebook look at the RHS and DNF ads displayed; thus, ascertaining the differences in visual attentions of Facebook ads were generated as follows.
- 1.
To investigate how RHS and DNF Facebook ads were gazed by participants with different interpersonal relationships.
- 2.
To explore the differences in visual attentions of the ROIs between participants with different interpersonal relationships while browsing RHS and DNF Facebook ads, respectively.
Based on the previous literature review, this study intended to examine the differences in eye measurements of TFD and NOF of Facebook ads among participants with difference interpersonal relationships. Thus, the experimental analysis was conducted to observe the participants' visual patterns via eye tracking technology. To thoroughly examine how participants gazed at ROIs of RHS and DNF Facebook ads, we conducted this study to examine participants’ visual attention in terms of their eye-movement patterns as they were given a Facebook page. Therefore, this study proposed four research questions and hypotheses:
- 1.
Is there a significant difference in TFD of RHS ads among participants with different interpersonal relationships?
- H 1

This study uses non-probability sampling and university students from a certain northern technology university as participants. The participants were divided into Facebook friend and non-Facebook friend groups based on their relationship with the researcher on Facebook's community platform. The participants in the Facebook friend group are friends who automatically follow the researcher and may see each other's posts in news feed on Facebook page. They have common friends, topics or clubs and
Hypothesis testing
The study discusses the eye movement distribution of visual attention on different ROIs by participants with different interpersonal relationships from the researchers when browsing Facebook pages. Independent samples T test was conducted on the TFD and NOF for different ROIs of the two participant groups. The judgment standard for the T test is the p value (Probability estimate), p < .05 is significant. For greater values, the opposite is true. The effect size of the T test is d. For d ≧ 0.2,
Conclusions
This study mainly discussed the differences in the visual attention given to the Facebook ads on the right side of page and sponsored stories on Facebook's community platform viewed by different interpersonal relationships. According to the TFD, the results experimented by eye tracking showed that the regardless of whether the participants are Facebook friends or not, they spent few time viewing the Facebook ads on the right side of the page and the sponsored stories section.

2022, Journal of Business ResearchCitation Excerpt :We chose a fixed exposure time of 15 s because: 1) some pilot studies with post interviews had been conducted before the formal experiment, indicating 15 s as optimal; 2) according to the advertising literature, an appropriate fixed (vs. free) exposure time could avoid a dilemma that there is too short a time for participants to see the pictures clearly or too long for them to become fatigued and exhibit redundant fixation. ( Bergkvist, 2017; Wang & Hung, 2019; Wang & Sparks, 2016); 3) Orquin and Holmqvist (2018, p. 1651) recommend a rule that it is advisable not to use a fixed exposure time design in the eye-tracking/advertising study because it may reduce realism, ‘but there are, of course, situations in which it is required’.
