Despite of its strategic role in shaping corporate image, Instagram predicts that 70% of its contents are not seen by users due to content overload and saturation problems. As more than 95 million photos are shared on Instagram on daily basis, when accessing Instagram, users are bombarded with a lot of visual information and consequently tend to selectively choose photos to pay attention to. Therefore, it is important for marketers to design an ads that has the ability to stop consumers and hold their attention for enough time to be processed cognitively before they scroll up or down to see other photos. This study investigates how visual aesthetic, vividness, and message type of pictures posted on Instagram affects customer responses. A content analysis of 3,952 brand content posted between July and December 2017 was conducted from the official Instagram accounts of seven global luxury brands. The top-listed brands on the Luxury Fashion Social Index namely Burberry, Calvin Klein, Chanel, Gucci, Hermes, Louis Vuitton, and Prada; were investigated as they were considered as good representatives of luxury brands with good social media presence. The coding guide in this study included the numbers of consumer responses (likes and comments), visual aesthetic (classical and expressive), vividness (high and low), and message type (literal and symbolic). For the independent variables, binary coding was used. ANOVA was used to test the hypotheses. Findings suggest that brand posts using expressive aesthetic image received more likes and comments on Instagram than the ones with classical aesthetics. Brand posts with high level of vividness receive more likes and comments than the ones with low level of vividness. Brand posts adopting using symbolic message receive more likes and comments than the ones implementing literal message. The results also suggest that there was a significant interaction between visual aesthetics, vividness, and message types in generating likes Brand content on Instagram using a combination of expressive aesthetic, high vivid, and symbolic message generates more likes and comments than any other combinations. Instead, the content adopting a combination of classical aesthetic, low vivid, and literal message produced the least responses. From theoretical perspective, findings can extend and modify media richness theory to luxury brand and social media contexts. Instagram can be used to display brand contents with various levels of vividness. This study imply that luxury consumers favor expressive aesthetics and symbolic message more positively indicating that they tend to have high level of need for cognition in consuming brand messages. Luxury brand marketers can increase their cognitive load by increasing the level of information complexity increasing the number of colors or patterns, using metaphoric statements, or crafting symbolic messages when creating brand posts on Instagram.

Advertising is important for tourism and past research has demonstrated its cognitive, affective and behavioural effects on consumers (e.g., Vakratsas & Ambler, 1999). These effects are largely dependent on how well viewers process advertisements that contains different elements, such as image, description and slogan. Images are particularly important to tourism advertisements and most tourism advertisements include images of the advertised destination. This paper proposes a conceptual model which explores the influences of image vividness and image congruity on the effectiveness of ecotourism advertisements. The Meaning Transfer Model (e.g., McCracken, 1989) suggests an object’s meaning can be transferred through images. This model has been widely adopted in advertising because most advertisements contain images. Images are believed to help transfer the intended advertising meaning and intention of the advertiser (Shimp & Andrews 2013). Most previous advertising research has focused on meaning transfer through the use of celebrity endorsers (e.g., Campbell & Warren, 2012; Hanrahan & Liu, 2013) whilst limited studies have examined key factors that influence the success of a meaning transfer from an advertising image to the advertised brand . Image vividness is believed to be one of the important factors that can influence the success of a meaning transfer (Nisbett & Ross, 1980). However, findings from previous research on image vividness are far from consistent. Some findings suggest that image vividness facilitate imagery processing and subsequently increase advertisement and brand favourability (Fennis et al., 2012) whilst other findings suggest that image vividness has no direct impact on attitude formation or persuasion (Taylor & Thompson, 1982). Recent research suggests that, advertising elements, in particular image vividness, may play an important role in forming the attitude towards the advertisement as well as the travel intention towards the advertised destination (Pelsmacker et al., 2002; Rasty et al., 2013). Besides image vividness, image congruity may be another important factor in determining the success of a meaning transfer through advertising images (Shimp & Andrews, 2013). Congruity has been widely studied in the field of consumer behaviour (Sirgy, 1990; Wang et al., 2009). McLaughlin (2009) categorised advertising congruity into four types (advertisement and context congruity, advertisement and product congruity, advertisement and advertiser congruity, and advertisement and other commercial component(s) congruity). Image congruity with the advertised product category has been identified as one of the most important advertising congruities (Chandon et al., 2000). Congruent advertisements are better than incongruent advertisements in generating positive attitudes or feelings towards an advertisement. For example, Kamins et al. (1991) found a viewer’s perceived congruity between the emotions reflected in a tourism advertisement and the media invoke more positive attitude towards the advertisement. Further, Rifon et al. (2004) found congruity between the description of an advertisement (ad description) and an advertising website used to display the advertisement resulted in more positive attitude towards the brand. Congruent advertisements can also generate a better purchasing intention. Kamins et al. (1991) found congruent advertisements were better at invoking an intention to use an advertised service. Conversely, incongruent advertisements lead to frustration or other negative feelings or a less favourable attitude towards an advertisement (Mandler, 1981). Australian ecotourism advertisements are selected as the context of the current study. Ecotourism is a nature-based tourism that focuses on preserving the environment, benefiting local economies and educating travellers (Weaver, 2008). Although ecotourism is rapidly developing in the last decade, the effectiveness of ecotourism advertising has been rarely researched, perhaps because ecotourism is still a relatively new area of tourism (Hughes et al., 2005). Reiser & Simmons’s (2005) study is among a handful of studies which have investigated the effectiveness of ecotourism advertisements. Their study found that ecotourism labels helped develop a positive attitude towards an advertisement and the advertised destination. Additionally, Chang et al. (2005) found that the use of a celebrity aboriginal endorser was more effective in achieving a favourable attitude towards an advertisement than was the use of a non-celebrity aboriginal endorser. Ecotourism advertisements often use three major types of images (scenery, animal and people) (Morgan & Pritchard, 2001). However, no empirical studies have examined the meaning transfer between image and advertising responses within the ecotourism context. People’s Republic of China is a critical market for Australian tourism and it is Australia’s second largest tourist source country (Australian Bureau of Statistics, 2014). Chinese tourists ranked first in terms of total trip expenditures (a total of $5.7 billion in 2014) (Tourism Research Australia, 2015). By 2020, China is expected to become Australia’s largest source country (Tourism Australia, 2011).The ecotourism market in China has risen in the past decade since its introduction in the 1990s (Cheng et al., 2013; Zhong et al., 2007). There were 1.9 billion domestic trips in China in 2009, of which 333 million were ecotourism trips. Around 80% of China’s nature reserves now have some form of ecotourism feature (Chappell, 2012). Chinese ecotourists are increasingly interested in taking overseas ecotourism trips. However, no previous study has empirically examined Chinese ecotourists’ attitude towards foreign ecotourism advertisements, which provides the opportunity for the current study. Based on the above discussion, the paper proposes positive relationships among image vividness, image congruity, attitude towards the advertisement and travel intention towards the ecotourism destination. Empirical research will be carried out in the future to test the proposed relationships. The theoretical framework can also be extended by including other advertising effectiveness measures such as comprehension or emotion (MacKay & Fesenmaier, 1997) so as to develop a better understanding of Chinese ecotourists’ responses to ecotourism advertisements.

By means of a field experiment, corporate brand posts on Facebook are analyzed regarding their effect on brand fans’ post recall capability, attitude toward the brand, and purchase intention. Results indicate that Facebook brand posts are able to positively influence fans’ attitude toward the brand. A significant interaction effect between the level of product involvement and the degree of brand posts’ interactivity and vividness is found. Implications for marketing research and practitioners are discussed.
