We employed a bibliometric approach to address the research questions through a reliable, scientific, and data-driven process for analyzing the selected studies. This paper investigates 210 scientific studies published from 2020 to 2021. In addition to a co-citation analysis, this study employed a bibliographic coupling keyword analysis to recognize emerging research topics and reveal a picture of emerging research clusters in the advertising research field. A list of the leading publications and journals considered is also provided at the beginning of the results section (Section 3).
This study aims to contribute to the advertising literature in multiple ways. First, this paper identifies the key themes of advertising research during the pandemic. The findings of this study provide valuable insights into how different advertisement appeals and communication channels were used during the pandemic. Second, this study explores how researchers have applied different theories in the literature published on advertising during the pandemic. By understanding the application of these different theories, the bibliometric review contributes to the theoretical development of the field of advertising research during pandemics. Third, the paper offers some practical recommendations to practitioners and managers regarding advertising strategies to be used during and after a pandemic. Fourth, and finally, this bibliometric review makes suggestions for the future research agenda on pandemic-related advertising. Based on the findings of this review, we discuss these contributions in Section 4.1.
Advertising campaigns can play a critical role during public health crises or pandemics ([
Like the other pandemics in history, the COVID-19 pandemic also attracted the attention of researchers. Reviewing and synthesizing such research through this bibliometric review can help future researchers and practitioners understand the role of advertising during pandemics. Moreover, this review may have implications for future advertising strategies, message strategies, and media strategies for post pandemic times and during any unfortunate health crises or pandemics.
The prime objective of literature reviews is to map and appraise the available literature and identify contributions and research gaps. It is vital to apply an iterative process and a structured methodology to conduct and achieve the targeted outcomes in literature reviews ([
A bibliometric analysis also provides visualization and mapping software for quantitative analyses ([
We searched and constructed our literature dataset from the Web of Science (WOS). Our dataset included articles written in the English language only. The prime objective of the study was to synthesize and categorize research that examined the impact of the COVID-19 pandemic on advertising from different perspectives. We initiated the collection of our dataset by inputting the key research terms sequentially into the topic field. First, we entered the two main keywords, "Advertisement" and "Advertise," into the topic field. We selected "All Years" in the timespan field and included the SCIEXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, BKCI-S, BKCI-SSH, and ESCI indexes in the search process. The date limit for searching the complete WOS core collection was set to 31 December 2021. Subsequently, we added the terms "COVID 19," "COVID," or "Pandemic" to ensure that we got a comprehensive list of relevant articles. The stepwise retrieval process resulted in 225 published studies. Next, we manually cleaned and refined the dataset based on language, relevance to the topic, and type of publication. Finally, we retrieved 210 studies to conduct the bibliometric analysis. This rigorous selection procedure ensured that each study included at least one of the chosen keywords in its title, keywords, or abstract. Figure 1 shows the data collection procedure for this study.
We applied bibliometric coupling and retrieved the fourteen most-cited publications. The most-cited paper was by [
First, the authors applied the bibliographic coupling algorithm to classify the leading journals that published the highest number of research articles on advertising during the pandemic, i.e., those having the maximum number of total citations (TC) and average norm citations (ANCs). Based on the number of publications, the International Journal of Environmental Research and Public Health was the leading journal, with 21 publications and 170 citations. The Journal of Advertising ranked second with 12 publications and 30 citations. Sustainability was in third place, with seven (
BMC Public Health had three publications and 27 citations. Journal of Adolescent Health and Journal of Business Research had two publications each, with 52 and 41 citations, respectively. Public Health and Media International Australia (MIA) published two articles with 15 and 14 citations, respectively. Two Spanish journals were also in the top fifteen journals listed. Profesional De La Informacion had a Q3 citation index in the WOS and Q1 in Scopus, while Tripodos, another international Spanish academic journal, published English articles about the world of communication.
We conducted a text mining analysis of the authors' keywords, the selected articles' titles, and their abstracts. This analysis provided the network and density visualization between our main constructs related to advertising and COVID-19. The network visualization diagram (see Figure 2) represents the items (i.e., constructs) by their labels and circles. The size of each label and circle defines a construct's significance (also referred to as an item's weight). A construct of higher significance will have a larger label and circle. In Figure 2, the labels of some items are not visible due to overlapping labels. Each item belongs to a cluster represented by a specific color. The lines between the items represent links, and their thickness represents the strength and quality of a connection.
Three thematic clusters based on this network visualization, i.e., red, green, and blue, emerged (see Figure 2). The red thematic cluster (C1) includes public-health-related variables/keywords strongly connected with the COVID-19 pandemic. Age, depression, anxiety, mental health, care, and infection are the leading keywords in this cluster (see Table 3). Consequently, we classify C1 as the public health (PH) cluster. The green cluster (C2) includes keywords such as advertisement, brand, consumer, crisis, message, reason, spread, uncertainty, and virus. These keywords are closely associated with various advertising terms utilized during the pandemic to provide information about COVID-19, create public awareness, and lower overall public apprehension. C2 is the crisis information and stakeholder (CIS) cluster. The blue cluster (C3) comprises keywords that reflect the utilization of media and social media channels in advertising various messages during the pandemic. Communication, Facebook, Instagram, medium, opportunity, Twitter, and website are the leading keywords in this cluster. We categorize C3 as the communication channels (CC) cluster.
Figure 3 is an overlay visualization that describes the focus of research topics from the outbreak of the COVID-19 pandemic to the end of 2021. The dark blue words represent the dominant words used by researchers in the initial phase of the pandemic. Terms such as 'communication,' 'recommendations,' 'support,' 'patient,' 'health,' 'care,' etc. demonstrate the high levels of global uncertainty that existed when enlightening the public on the pandemic. This cluster also evidences the lack of knowledge of advertising stakeholders and researchers in understanding the phenomenon. As time passed, words such as 'virus,' 'COVID virus disease,' 'outbreak,' 'government,' and 'website' showed an emerging clarity on the nature of the pandemic. Next, the advertising terms in the light- and dark-green-colored circles, such as 'crisis,' 'risk,' 'age,' 'challenge,' 'reason,' 'infection,' 'anxiety,' 'quality,' and 'life,' come into focus. This cluster displays the emerging advertising focus on giving a clear preventative message to the public and minimizing the rising number of fatalities. Indirectly, these terms reflect the mounting loss of human life globally and focus on ways to mitigate this.
The yellow advertising terms reflect the current/latest advertising research. Terms such as 'consumer,' 'mental health,' 'exposure,' 'Facebook,' 'Twitter,' 'advertisement,' 'majority,' 'symptom,' 'self,' and 'uncertainty' demonstrate a strong reliance on social media channels to communicate essential COVID-related advertising messages to those likely to have been most affected by the pandemic. Such a focus shows the maturity of advertising agencies in conveying the right messages. During this period, COVID-19 vaccinations were still in the development stages. Therefore, the term 'uncertainty' may indicate researchers' concerns about discerning the right treatment method.
To understand the contextual, practical, and theoretical implications of their work, researchers employed various theories to examine the different dimensions of advertising during the COVID-19 pandemic. The leading theories used were protection motivation theory, Taylor's six-segment message strategy, agenda setting theory, terror management theory, grounded theory, temporal self-regulation theory, and the theory of planned behavior. An overview of the different theoretical clusters is shown in Figure 4 and Table 4. Out of the 210 studies, 15 explicitly applied theoretical lenses (see Table 5).
- Cluster 1: Protection Motivation Theory
Protection motivation theory (PMT) and Taylor's six-segment message strategy wheel are part of the first cluster. PMT is a health psychology theoretical framework that aims to understand how humans process threats and select responses to deal with the risks that they bring ([
Taylor's six-segment message strategy wheel is applied to develop a messaging strategy. This theoretical approach was often used to create and promote a communication strategy that curtailed the elements of fear and anxiety at the start of the COVID-19 pandemic. [
- Cluster 2: Agenda Setting Theory
Agenda setting theory, also known as the agenda setting function of the mass media, is in the second cluster. This theory underscores that by choosing and displaying specific news, a new media channel can play a role in forming a campaign agenda on a certain subject. Viewers understand a particular issue depending on the level of information provided and its status in the news. Moreover, news media can strengthen or diminish the importance of a given subject by fluctuating the value given to the campaign. This theory was extensively applied in providing specific health information about the COVID-19 pandemic in health advertisements that were broadcast to the public ([
- Cluster 3: Terror Management Theory
Terror management theory, which is applied to explain anxiety about death, is in the third cluster. This theory postulates that humans are conscious that death is an uncontrollable, inevitable, and non-predictable fact ([
Terror management theory describes how the fact of mortality is applied to mitigate death anxiety and affects consumption outcomes. Researchers also explored the role that images of death played in enhancing consumers to make pro-social decisions during the pandemic. For instance, utilizing the terror management theory, [
- Cluster 4: Grounded Theory
The contributions in Cluster 4 use grounded theory ([
- Cluster 5: Temporal Self-Regulation Theory
Temporal self-regulation and planned behavior theories are in cluster 5. Temporal self-regulation theory suggests that an individual's health behavior is regulated by their intention strength, behavioral prepotency, and self-regulatory capacity ([
- Cluster 6: Theory of Planned Behavior
Planned behavior is a psychological theory that links beliefs to behavior. This theory argues that three core components, namely, attitude, subjective norms, and perceived behavioral control, shape an individual's behavioral intentions. Researchers applied planned behavior and temporal self-regulation theories in tandem to find psychological predictors that resulted in COVID-19 prevention behaviors and habits, such as proper hand hygiene. [
During the pandemic, delivering honest, believable, timely, and effective messages to consumers became a paramount concern for the advertising industry. Nevertheless, broken global supply chains and business uncertainty made it hard for businesses to fulfil the commitments they made in their advertising messages. With growing global anxiety about COVID-19, consumer behavior changed in a short period of time and necessitated drastic changes in the field of advertising research. Governments and businesses gradually became dependent on digital and social media platforms to disseminate critical pandemic-related messages to a fear-ridden and locked-down public.
In analyzing a sample of over two hundred research publications, this study offers insight into how the pandemic created human anxieties that changed the advertising research field globally. Such public concerns were instrumental in changing the focus of advertising-related research during the peak pandemic period. Fear of death, COVID-19 treatments and remedies, depression, and other human health fears emerged as leading issues for advertising research during the pandemic. Providing credible and truthful messages was the dominant feature demanded by consumers in all COVID-19-related advertisements. For instance, the initial attempts by AstraZeneca to downplay the side effects of its vaccine is a good example of how trust was broken between pharmaceutical companies and global consumers.
This study identifies the advertising research trends and theoretical lenses utilized to investigate advertising aspects during the COVID-19 pandemic. In doing so, it identifies three thematic clusters through text mining. These clusters underscore that the impact of COVID-19 on advertising research has been multi-disciplinary and requires a holistic research approach. The first cluster (PH—public health) represents the concerns of advertisers and researchers for the health of their target public/audience. These public health areas are mainly related to the target audience's physical health (e.g., infection) and mental health (e.g., anxiety and depression). Advertisers have widely used health concerns through fear-based emotional/affective appeals in their marketing communications during the pandemic. Viewers observed a fair number of advertisements in different media motivating the public (including customers) to exercise precaution and minimize the risks associated with COVID-19. Some examples include advertisements highlighting the importance of care, quality, life, and support. Researchers have accordingly tried to address such health-related concerns in their studies.
The second thematic cluster (CIS—crisis information and stakeholders) reveals the concerns of advertisers in communicating the necessary crisis-related information to relevant stakeholder groups. Based on the leading keywords (see Figure 2), consumers and governments appear to be the most important stakeholders. Many governments opted to utilize active advertising to create awareness, minimize uncertainty, and control the spread of the COVID-19 virus during the pandemic ([
The third cluster (MC—media channels) represents the choices of advertisers and interests of researchers concerning media selection for communicating the advertising messages. The leading keywords show that social media dominated as the preferred advertising channel during the pandemic, with Facebook, Instagram, and Twitter emerging as key media communication vehicles. This cluster demonstrates that during the pandemic, increasing consumer usage of social media to inform decision making can motivate businesses to excessively use social media marketing ([
Another key objective of this bibliometric review is to summarize the theoretical deviations and adaptations applied to advertising research during the pandemic. The theoretical lenses used and their context connectivity along with relevant keywords are presented in Table 4. Theoretical frameworks, such as the theory of planned behavior, temporal self-regulation theory, terror management theory, agenda setting theory, and protection motivation theory, aided researchers in examining and understanding how advertising worked and/or what affected advertisements during the crucial time of the pandemic. Similarly, grounded theory allowed researchers to explore people's perceptions of the impact of COVID-19 ([
This study makes the following contributions by using the bibliometric review technique. First, it identifies three thematic clusters in the research on advertising during the COVID-19 pandemic. These clusters are objectively identified through network visualization by text mining. Our findings provide useful insights into how different advertising appeals and message strategies were utilized in pandemic-related advertisements. The thematic analysis of the research conducted during the pandemic reveals that advertisers used both affective and cognitive advertising appeals/message strategies. This review also identifies social media usage as a key area of interest for advertising research during the pandemic. The selection of appropriate media may have meaningful implications for how to produce effective and trustworthy pandemic-related advertisements in the future.
Second, this study identifies the different theories researchers have used in the published literature on advertising during the pandemic. It also provides an understanding of how researchers extended the application of each identified theory (see Table 5) within such an unusual context and research setting. Thus, our review contributes towards a better understanding of the theoretical development of our selected field of research (i.e., advertising during the pandemic).
Third, based on a bibliometric review of the shortlisted literature, this study provides useful recommendations for practitioners/managers and helps them better understand how the pandemic affected advertising. Such recommendations are related to two priority areas: (
Lastly, this bibliometric review presents an agenda for future research, particularly on pandemic-related advertising. This agenda may assist researchers in identifying priority areas for future research related to key themes, theories, and research settings.
Our bibliometric review has two major theoretical contributions. First, this review adds to the literature on advertising during pandemics or health crises by synthesizing the available literature through a bibliometric analysis. In this way, the key themes or trends of the advertising research conducted and published during COVID-19 pandemic are identified. This review also reports some key characteristics of the research on advertising during COVID-19, for example, the most-cited publications and leading journals. Secondly, this review identifies the theories that were used, tested, or elaborated in the literature on advertising during COVID-19. In this way, this review reports on the theoretical development of research on advertising during pandemics or health crises.
Our bibliometric review outlines salient trends in advertising observed during the COVID-19 pandemic. Accordingly, this study's findings provide managers with valuable insights into formulating advertising objectives and messaging strategies (i.e., cognitive, affective, and/or conative) when consumer markets face global health crises. Our findings are also helpful for managers who apply evidence-based management standards to understand new marketing requirements and organize advertising operations accordingly. This approach can be successful for managers in developing best practices for solving real-life business problems. The literature (e.g., [
The pandemic might have generated new consumer segments ([
Key advertisers including businesses and governments may learn important lessons from advertising during the pandemic. They should stay connected to their target audience through their advertisements in such critical times. They must keep their audience informed about the crisis and what preventive measures to take, but also communicate feelings of care, support, and social responsibility. Similarly, post pandemic or crisis-related advertisements and other integrated marketing communications should help audiences get back to normal life in a smooth and pleasant way.
Advertisers must not underrate the significance of the mental health of their target market during any pandemic or physical health crisis. Creating awareness about any pandemic and its physical health hazards is important; however, the mental health hazards (e.g., anxiety and depression) associated with a pandemic should also be highlighted in advertising campaigns. Moreover, how to cope with mental health issues or hazards during a pandemic should be a key feature of pandemic-related advertising campaigns.
Advertising during pandemics may provide an opportunity for organizations and brands to develop their image of being 'socially responsible' and improve their social performance. Such social performance may enhance the corporate reputation that may further increase customer trust and customer loyalty ([
Our review finds that when target markets (including the general public) and consumers face serious health challenges, social media platforms emerge as one of the most effective marketing communication channels. Our findings show that social media platforms may allow firms and governments to stay connected to their target audience. In this way, our review provides some important implications to help managers better plan their future advertising campaigns during the pandemic and in the post COVID era. However, any variations in the intensity of a pandemic or crisis may affect the advertising trends identified here and therefore also content-related managerial decisions.
This section presents a prospective agenda for future research, based on the findings of this bibliometric review. In addition, some opportunities for future research arise from the methodological and scope-related limitations of this bibliometric review. These are briefly referred to in Section 4.4.
This review identifies three key clusters or trends in advertising research during the pandemic, i.e., public health, crisis information and stakeholders, and media channels for communication. Future researchers may particularly wish to focus on the usage and effectiveness of different cognitive and affective advertising appeals/messaging strategies, and/or the selection of media channels for communication.
Within the identified themes or clusters, this review presents a variety of keywords and variables (see Table 3) that may spark the interest of future researchers. The conceptualization/definition, social construction, measurement, and/or proposed usage of these variables/constructs in relation to expected antecedents and consequences may offer multiple research opportunities for future researchers.
This review has highlighted the different theories that researchers have used in their studies on advertising during the pandemic (see Table 5). Testing the assumptions, key aspects, and/or applications of these theories in the context of pandemic-related advertising could be of interest to future researchers. The application of such theories and/or other theoretical lenses may also help future researchers assess how post COVID advertising should be designed.
The pandemic has created some new consumer segments for marketers ([
Our study has some limitations. First, we used the Web of Science (WoS) database to identify and collect research articles. Our research findings would have more authority if we had also included articles from other databases, such as Scopus. Future researchers may consider including multiple databases in their bibliometric reviews. Second, this study applied bibliometric analysis techniques. However, this approach does have a few shortcomings. For instance, changing the keywords would alter the sample noise, including unrelated articles or excluding related articles. However, this limitation of our analysis has only a limited chance of creating errors in our study as it covers only a two-year period. Finally, this study does not outline the research methodologies and specific contexts applied in the selected studies. Future bibliometric studies may wish to include these areas. Nevertheless, this study provides a synthesized interpretation of the impact of the COVID-19 pandemic on advertising research.
Our study's goal was to better understand the impact of the COVID-19 pandemic on advertising research. By utilizing an appropriate database, data collection methods, and analytical tools, we met these research goals. Our analysis provides a well-organized overview of the vital thematic trends and theoretical frameworks used in advertising research during the COVID-19 pandemic. We hope that our results offer new insights for researchers investigating advertising theory and practice.
