Consumers Attraction to Purchase Online: Website Quality as a Major Influencing Factor ()
1. Introduction
The world has experienced a phenomenal technological transformation after the ban on using the internet for commercial activities was lifted in the early 1990s. This significant move made e-commerce possible, although certain activities in the prior years could be regarded as e-commerce. E-commerce has grown significantly over the past years because it has a larger geographical market than the traditional market. An e-commerce business does not require a consumer to be present at their premises before purchasing a product as buying a product is mainly online or on their website (Ahn et al., 2007; DeLone & McLean, 2004). The introduction of the internet has made it possible for business owners to create a website that enables consumers to search for products and place an order online. And with functions like escrow payment system, addition of new payment method, on-site verification of e-retailers, designing the website in multiple languages, viewing products in multiple currencies, and many more, E-commerce companies such as Amazon, Alibaba, Walmart, Wish, and others over the past years have added more functions to their websites and have also improved their website and its interface to enhance a better shopping experience, thus, suggesting that Ghanaian online consumers shop in an online shopping platform with good website quality.
Consequently, Chen and Cheng (2009) and Bai et al. (2008) affirmed that an e-commerce website quality tends to improve an online consumer purchase intention. When an online consumer purchases a product online, the online shop ships the products to their delivery address provided. These days, customers can also interact with an online shop on the shopping website because of its improvement. On top of this, most e-commerce websites such as Alibaba and Amazon also provide tracking information of an order in a website without necessarily visiting a shipping and logistics company website to track the order, mostly in the case of third-party logistics. An e-commerce business’s success to some extent depends on its capability to maintain their existing customers whilst ensuring that they can attract a new customer. One way to achieve this is to have a good and a functionable website. This is because, Ghanaians generally perceive electronic technological for business transactions to be very risky (Awiagah et al., 2016) because of poor website infrastructure (Mintah, 2018). Hence, to retain and attract new customers to an online shopping platform, e-commerce businesses need to have significant insight into what online consumers expect for a website’s quality (Van Riel et al., 2004). To Hsu et al. (2014), some shopping websites retain and attract more online consumers than other shopping websites because they have an outstanding design and are easy to navigate. Also, Shin et al. (2013) opined that a key success for an e-commerce business is to have a good website.
Many researchers and scholars, including (Gao & Li, 2019; Hsieh & Tsao, 2014; Pandey & Chawla, 2016; Shin et al., 2013; Wright et al., 2019), have conducted a lot of studies on the influence of website quality constructs on online shopping worldwide. However, to the best of our knowledge, it appears that no or limited studies have been conducted in Ghana on the subject matter. Consequently, this research sought to examine how website quality constructs influence online shopping among Ghanaian consumers while moderated by commitment.
The remainder of the research is as follows. The next section presents the theoretical background and hypothesis development based on the literature reviewed. This will be followed by the research methods and then continued with the data analysis. The next section will discuss our input and contributions to the study both research and practice. The last section will present the limitations and future research.
2. Theoretical Background
2.1. Website Quality
In e-commerce, a website serves as a place where a seller and an online consumer meet to transact. In this regard, online shopping’s effectiveness and success depend on a website or the online shopping platform. Consequently, Aladwani and Palvia (2002) see website quality as assessing a website system’s general performance. According to the researchers, such quality is subjective, and a high website rating indicates that a website’s features meet a user’s need. Chang and Chen (2008) measure a website user assessment of a website. A website user will conclude as to whether a website meets their needs based on the evaluation.
Previous studies reveal that website quality is a multi-dimensional construct with several dimensions (Aladwani & Palvia, 2002; Delone & McLean, 1992; DeLone & McLean, 2003, 2004; Hoffman & Novak, 2009; Loiacono et al., 2002; Urban et al., 2009; Wolfinbarger & Gilly, 2003). However, it has been widely recognized that website quality comprises three constructs; information quality, system quality, and service quality (Delone & McLean, 1992; DeLone & McLean, 2003, 2004). Consequently, the study employs these three as website quality constructs.
In an e-commerce website, information is the content that explains a product offering. According to Hsieh and Tsao (2014), such content should be relevant, complete, personalized, and easily understandable by an online consumer. Therefore, DeLone and McLean (2003) opined that information quality means the quality of a website’s content. A higher information quality speeds up an online consumer purchasing decision. Hence, an e-commerce website with a higher information quality is likely to generate more traffic from online consumers, subsequently leading to the actual purchase, than other e-commerce websites with low information quality (Tsao et al., 2016).
An e-commerce website’s system quality is the general performance of a website system perceived by online consumers (Chen et al., 2015, 2017). According to DeLone and McLean (2004), system quality includes vital features such as availability, system usefulness, suitability, reliability, and response time. Online shopping is generally portrayed to be more convenient than traditional shopping. Therefore, an effective system quality would provide an online consumer a pleasant shopping experience, influencing their shopping behaviors (Tsao et al., 2016).
Regardless of the information provided by an online retailer in their online store, an online consumer may seek additional information before arriving at a final purchasing decision. Service quality comprises all phases of online consumer interaction with an e-commerce website (Parasuraman et al., 2005). E-commerce website service quality focuses on helping an online consumer effective and efficient online transaction. DeLone and McLean (2003) opined that it involves assurances, responsiveness, and reliability on the online retailer.
2.2. Online Shopping Behavior
E-commerce or online shopping takes place online. Bhattacharya and Mishra (2015) asserted that online shopping behavior comprises all behaviors relating to e-commerce. It includes visiting e-commerce or online shopping platform, searching for product information, ordering a product, enquiring more information from an online seller about a product, delivery schedules, and so forth (de Kerviler et al., 2016; Paluch & Wunderlich, 2016). Online shopping in advanced countries is high and has been generally accepted by the public but is relatively low in developing countries because of infrastructural challenges and some negative perceptions associated with buying online. According to Bhattacharya Mishra (2015), such negative perception is mainly the fear of shopping online. Consequently, Ghanaian consumers prefer the traditional shopping method (Domeher et al., 2014) and are likely to rely on early online consumers to purchase a product online.
2.3. Commitment
Commitment is rooted in relationship marketing, and it helps an online retailer and online consumer establish a long-term business relationship (Garbarino & Johnson, 1999). It is used to distinguish successful relationships from unsuccessful relationships (Roberts et al., 2003). Commitment has been defined by Ogba and Tan (2009) as an emotional feeling as a willingness to maintain a relationship with a retailer or brand. The researchers further added that commitment goes beyond a mere repurchase from the same retailer or brand. The definition implies for there to be a commitment between an online retailer and an online consumer, and both parties must be willing to make some sacrifices to maintain a long-standing relationship. In past literature, commitment has been found to have a significant positive relationship with behavioral intention (Fullerton, 2014; Moreira & Silva, 2015; Shukla et al., 2016).
3. Model Constructs and Hypothesis Development
Figure 1 presents the proposed model of the study. The model intends to explain Ghanaians online shopping behavior in e-commerce. Website quality construct is considered the primary predictor of online shopping among Ghanaians with three constructs; information quality, system quality, and service quality. The model also proposes that commitment will mediate website quality construct and online shopping behavior.
3.1. Information Quality and Its Effects on Online Shopping Behavior
An e-commerce website’s core is to provide accurate information on varieties of
product offerings to online consumers. Thus, online consumers are much more interested in online retailers’ product content as it helps them differentiate online retailers of high-quality products from those of low-quality products. Empirical evidence reveals that an e-commerce website’s information quality positively influences online consumer shopping behavior. In their studies, Kim and Lim (2001) and Palmer (2006) found that information quality helped attain website success and consumer satisfaction. Lin and Lu (2000) also found information quality a relevant factor that affects online shopping behavior. Lin and Lu (2000) findings conform with Kuan et al. (2008), who found out that information quality is positively related to an online consumer purchase intention in their research. Hence, it is hypothesized that;
H1: There is a significant positive relationship between information quality and online shopping behavior among consumers in Ghana.
3.2. System Quality and Its Effects on Online Shopping Behavior
An e-commerce website service quality plays a vital role for an online retailer to arrive at a final purchasing decision. In an e-commerce website, a system quality denotes the efficient use of technology to ensure that an online consumer’s personal and sensitive information is secured while providing an easy navigation platform. In support of this, Shneiderman and Plaisant (2010) claimed that online consumers do not prefer to shop in an e-commerce platform with an unsecured payment system. Again, Schonberg et al. (2000) and Yoo and Kim (2000) opined that e-commerce platforms should ensure that their website is easy to use and navigate by online consumers. Palmer (2006) found out that an online consumer will be attracted to an e-commerce platform if the website is easy to navigate. According to Ajay and Potti Srinivasa (2017), the information quality is not enough for an online consumer to rely on and arrive at a final purchasing decision as they are much more concerned with the system quality. Again, Kuan et al. (2008) found out that system quality is positively related to an online consumer’s decision to purchase from a website. Therefore, it is hypothesized that;
H2: There is a significant positive relationship between system quality and online shopping behavior among the consumers in Ghana.
3.3. Service Quality and Its Effects on Online Shopping Behavior
Sometimes, a product description may not be enough for an online consumer to arrive at a purchasing decision. Consequently, they may seek additional information or clarification from an online retailer. Because e-commerce does not involve face-to-face interaction between the transacting parties, online retailers need to have reliable customer service to attend to their customers’ needs and concerns. Besides, the website must be reliable, thus, honoring all their promises. Literature available indicates that service quality influences an online consumer’s decision to purchase from an e-commerce platform. To Ajay and Potti Srinivasa (2017), service quality helps attain customer satisfaction, which eventually will lead to a purchase intention. At the same time, Sun et al. (2015) found out in their study that service quality affects online consumer purchase intention. Similarly, Kuan et al. (2008) found out that service quality affects online consumer purchasing intention. Thus:
H3: There is a significant positive relationship between service quality and online shopping behavior among the consumers in Ghana.
3.4. Moderation Role of Commitment
Commitment is vital when it comes to relationship building between an online seller and an online consumer. Commitment, in the long run, helps make an online consumer loyal to an online retailer. Previous research conducted by Lokhorst et al. (2013) had found commitment to influence behavior. Previous literature has paid less attention to the moderation effect of commitment on website quality constructs and online shopping behavior intention and behavior. The moderation effect of commitment is found in the relationship between consumer purchase intention and internet shopping behavior (Rehman et al., 2019). Drawing on this previous literature, we expect a moderating effect of commitment on website quality constructs and online shopping behavior. Hence, we prose the hypothesis:
H4: Commitment significantly and positively moderates the relationship between website quality constructs and online shopping behavior among the consumers in Ghana.
4. Research Methods
4.1. Measurement Development
The study’s conceptual framework was made up of three main constructs: website quality, commitment, and online shopping behavior. These constructs have been established in past studies. To compile a research instrument to test the research hypothesis, the researcher drew the past studies’ measurement items and was modified to suit the context of the study. The items in the questionnaire were originally derived from (Jayawardhena, 2004; Lee et al., 2006; Mintah, 2018; Mukherjee & Nath, 2007; Wixom & Todd, 2005).
A closed-ended questionnaire was developed to collect data from the participants. The questionnaire was made up of two parts. The first part focused on the demographic information of the participants. The participants were asked about their gender, age, online shopping experience, occupation, and educational level. The second part addressed the hypothesis posed on a seven-point Likert scale, with one (1) representing strongly disagree to seven (7) strongly agree. The independent variable, website quality, had three dimensions: information quality, system quality, and service quality. The information is the quality of the information on the online shopping platform, and it was measured using four items. The system quality, which focuses on the website’s performance in terms of usage, was also measured using four items.
Similarly, the service quality and the moderator, commitment, were also measured using four items. The online shopping behavior was measured using five measurement items. To ensure that the questionnaire was devoid of any form of error and ambiguity, a preliminary version of the questionnaire was reviewed by four Doctoral students namely; Evans Mensah (Agricultural Economics and Management), Isaac Nunoo (Agribusiness), Joseph Asante Darkwah (Finance) and Moses Agyemang Ameyaw (Business Administration).
4.2. Data Collection
The data collection was carried out in Ghana. The study sample was Ghanaians in Ghana who purchase items from an e-commerce platform(s). The e-commerce platforms for this research were both the local platforms and the cross-border e-commerce platforms. To better target the study’s desired participants, the researcher employed a web-based survey method as the means for data collection. The online version of the instruments was set-up on Microsoft Forms. A convenience sampling technique was used to select the participant from Accra Metropolis, the capital of Ghana. A message containing the purpose of the study and the Uniform Resource Locator (URL) was sent to the participant via WhatsApp Messenger. The participants participated in the studies voluntarily. Three hundred and seventy-two (372) responses were received within the specified period (December 14, 2020, to January 13, 2021) for data collection. The sample size was appropriate for the research given the sampling technique employed, the emerging e-commerce market in Ghana and the one-month period for the data collection.
5. Data Analysis
The researcher then employed a two-stage analytical procedure to analyzed the data obtained. Partial Least Square (PLS, SmartPLS Version 3.2.9) was used to assess the measurement model’s reliability and validity. Also, Statistical Package for Social Sciences (SPSS) version 26 was used to analyze the participants’ demographic data.
5.1. Respondents Demographic Information
Table 1 shows that among the sample pool of 372, most of them were male (54.3%), and the remaining were female (45.7%). In terms of age, the majority (40.3%) were from the age group of 20-25, followed by 26-30 (37.4%), above 30 years (18.8%), and below 20 years (3.5%). On online shopping experience, most of the respondents (34.9%) had 1 - 3 years of experience, followed by 4-6 years (30.4%) of experience, and then 7 - 10 years (14%) of experience, less than a year (11.3%) experience, and lastly, above 10 years (9.4%). With regards to occupation, most of the respondents (32.5%) were in the private sector. This was followed by students (24.2%) and then to the public sector (19.6%), self-employed (18.3%), and unemployed (5.4%). In terms of the level of education, the results from the table indicate that more than half of the respondents had a degree (56.5%), followed by Diploma (16.1%), and then Masters (15.3), Senior High School (7%) and lastly Ph.D. (5.1%).

Note: N = Sample size and % = Percentage.
5.2. Measurement Model
The researcher examined all the composite reliability scores and the indicator’s outer loading to assess the reliability (internal consistency reliability and indicator reliability) of the measurement model (Fornell & Larcker, 1981; Nunnally, 1978). All the composite reliability figures in Table 2 were above the cutoff value of 0.70. Again, all the Cronbach alpha of the constructs exceeds the standard of 0.7, signifying a strong internal consistency. We also assessed the convergent validity and discriminant validity. According to Hu et al. (2004), the convergent

Note: Sample size (N) = 372, CR = Composite Reliability, AVE = Average Variance Extracted, α = Cronbach’s Alpha, IQ = Information Quality, SQ = System Quality, SVQ = Service Quality, CO = Commitment, OSB = Online Shopping Behavior.
validity assessment builds on the average variance extracted (AVE) values. The researchers further said that the AVE should meet the benchmark value (>0.50). The results from Table 2 indicate that the AVE of each construct is well above the benchmark of 0.50, demonstrating high levels of convergent validity. Also, each indicator’s loading on its respective factor exceeds 0.70 (see Table 2). The data’s discriminant validity was assessed according to Fornell and Larcker (1981) procedure. Thus, the square root of AVEs of each construct should be larger than the values of the correlations between the construct and other constructs. Therefore, these test results in Table 3 show adequate discriminant validity.
5.3. Structural Model
The structural model was also assessed using the Partial Least Square (PLS, SmartPLS Version 3.2.9). The PLS approach was appropriate for the research because it is suitable for examining the casual relationship among latent constructs (Hair et al. 2011). The results are presented in Table 4 and Table 5 below. The path coefficients or the original sample of the constructs have a standardized value ranging from −1 and +1. The closer the estimated path coefficients are geared towards 1, the stronger the forecast relationship. Also, the closer the estimated coefficients to 0, the weaker the relationship. Observations of the coefficient in Table 4 and Table 5 show a positive relationship among all the construct, except the mediating role of commitment between information quality and online shopping behavior and between system quality and online shopping

behavior, although there are variations in the magnitude of the effects.
The results from Table 4 indicate that three out of the four hypotheses tested were accepted. For example, the results revealed that information quality (IQ) significantly and positively influence online shopping behavior (OSB) as (OS = 0.102, t-value = 2.126, p-value < 0.05). Again, service quality (SVQ) was found to have a significant and positive influence on online shopping behavior (OSB) as (OS = 0.179, t-value = 2.863, p-value < 0.01). Despite this, system quality (SQ) did not have a significant influence on online shopping behavior (OSB) as (OS = 0.055, t-value = 0.941, p-value > 0.05). The results also found that commitment (CO) has a significant and positive influence on online shopping behavior (OSB) as (OSB = 0.558, t-value = 7.943, p-value > 0.05) although was not part of the research hypothesis for the study.
Table 5 presents the moderation effect of commitment between website quality constructs and online shopping behavior. The table results indicate that there were no moderation effects between commitment and the other constructs. Thus, commitment (CO) does not moderate the relationship between information quality (IQ) and online shopping behavior (OSB) as (OS = −0.008, t-value = 0.143, p-value > 0.05). Also, commitment does not also moderate the relationship between system quality (SQ) and online shopping behavior (OSB) as (OS = 0.040, t-value = 0.674, p-value > 0.05). Lastly, commitment does not moderate the relationship between service quality (SVQ) and online shopping behavior (OSB) as (OS = −0.038, t-value = 0.798, p-value > 0.05).
6. Discussion and Contributions
6.1. Discussion of Findings
The study objective was to examine the influence of information quality (IQ), system quality (SQ), and service quality (SVQ) on online shopping behavior. Additionally, the study sought to find the moderating role of commitment (CO) between information quality (IQ), system quality (SQ), service quality (SVQ), and online shopping behavior (OSB) in the Ghanaian context.
Figure 2 is the Structural Model. Among the independent variables, information quality (IQ) was found to positively and significantly affect online shopping behavior (OSB). Thus, Ghanaian online consumers consider the information provided by online retailers on their product offerings on their website as beneficial
and helpful when considering purchasing online. It is therefore not surprising the Ghanaian online retailers will consider information provided on a website as a significant factor in their purchasing behavior because most Ghanaians prefer to buy from a traditional retailer (Domeher et al., 2014) where they can have the opportunity to examine the product before arriving at a purchasing decision physically. Consequently, the kind of information online retailers provides on their shopping platforms would influence their shopping behavior. Supporting past studies’ findings include (Kim & Lim, 2001; Kuan et al., 2008; Palmer, 2006).
Moreover, the study confirms a significant and positive relationship between system quality (SQ) and online shopping behavior (OSB). Thus, Ghanaian online consumers are concerned about personal and sensitive information such as their credit or debit card information, address information, and issues such as website interface and navigation. Generally, no consumer wants their payment information to be hacked and may be cautious when making an online payment. The finding of our work is in line with the outcome of Kuan et al. (2008); Palmer (2006) and Yoo and Kim (2000). It is reasonable that an e-commerce website’s system quality influences Ghanaian online consumer shopping behavior as information quality may not be enough to influence their shopping behavior (Ajay & Potti Srinivasa, 2017).
Similarly, service quality (SVQ) had a significant positive effect on online shopping behavior (OSB). The finding implies that Ghanaian online consumers consider the kind of services that e-commerce platform provides to them when shopping on their website or platform. Such service includes timely response to their inquiries and concerns and so forth. This finding is supported by Ajay and Potti Srinivasa (2017) and Sun et al. (2015), who in their studies found a significantly positive relationship between service quality and online consumer intention to purchase. The present research also detects a positive and significant effect of commitment (CO) and online shopping behavior (OSB). Commitment is seen as one of the foundations in relationship marketing, and it is essential for shaping online consumer loyalty to an e-retailer or a shopping platform. The finding confirms earlier findings of Fullerton (2014) and Shukla et al. (2016), who found commitment to have a significant positive effect on behavioral intention.
Nonetheless, commitment does not moderate the relationship between the website quality constructs (information quality, system quality, and service quality) and online shopping behavior. Thus, commitment does not alter the strength of the relationship between website quality constructs and online shopping behavior among Ghanaian online consumers, although commitment has a significant positive effect on online shopping behavior. The finding contradicts Rehman et al. (2019), who found a moderation effect of commitment between consumer purchase intention and internet shopping behavior among online consumers.
6.2. Contributions to Research
The results of this study provide some research contributions. First of all, the study contributes to the limited studies that have been conducted in Ghana. Although website quality constructs on online shopping have been widely investigated (Ajay & Potti Srinivasa, 2017; Wang et al., 2015; Zhou et al., 2009), not many studies on these variables have been conducted in Ghana. It is essential to note that consumer characteristics differ from country to country because of different cultural and technological backgrounds. The advancement of technology in the developed countries such as China, the United States of America, and the European countries may ease some of the challenges associated with buying a product from an e-commerce site. In general, the study’s findings imply that online retailers or e-commerce platforms who would like to induce Ghanaian online consumers’ willingness to buy from their platform ought to provide accurate or quality information, a good website system, and service quality. Finally, the study extends the research about website quality in e-commerce by investigating the moderation role of commitment. To the best of our knowledge and literature, not much work has been done on website quality and online shopping using a moderator’s commitment. As such, this research would offer additional insights into the salience of website quality in the context of online shopping.
6.3. Contribution to Practice
The study also provides several contributions that e-commerce platforms and online retailers may consider relevant in online shopping. First, the study’s findings suggest that information quality can increase Ghanaian online consumers’ shopping behavior. This indicates that, for e-commerce platforms or online retailers to maximize Ghanaian online consumers’ shopping behavior, they must improve the information they provide on their website and/or products. Quality product information can help minimize some doubts that online consumers may have. Also, system quality exhibits a significant positive influence on Ghanaian online consumers’ shopping behavior. E-commerce platforms need to provide a well-designed website that is easy to use and navigate and ensure that buyers’ personal or private information will not be leaked or hacked. There is also the need for e-commerce platforms to occasionally seek suggestions from their buyers on some of the functions needed to be added to their website to enhance customer satisfaction. At the same time, service quality tends to increase the online shopping behavior of Ghanaian online retailers. The finding implies that not all aspects of online shopping behavior can influence information quality and system quality. E-commerce platforms need to pay closer attention to their customer concerns as the cost of switching to a different platform or an online retailer may be zero. Finally, a commitment was found to have the capacity to influence online shopping behavior but has no moderation effect on website quality constructs and online shopping behavior. Therefore, e-commerce platforms or online retailers need to build a stronger relationship with their customers because retaining an old consumer is easier than gaining new ones due to the market’s competitive nature.
7. Limitations and Future Research
While the study aimed at investing the influence of website quality on online shopping behavior in the Ghanaian context, it has some limitations. First, several factors can influence Ghanaians, online consumers, in an online shopping platform, but this study concentrated on only website quality constructs. Future research should investigate other factors that can influence online shopping behavior among online consumers in Ghana. A second limitation is that the study focuses on online shopping behavior in Ghana. Future research should focus on testing the results in other emerging markets in Africa, as most studies have been conducted in advanced countries. Again, the research did not investigate the post review or reactions of Ghanaian consumers who shops on an e-commerce platform. The study recommends that future studies research Ghanaian online consumers’ reactions to shopping on an e-commerce site over time. Thus, a longitudinal study should be conducted to help extend understanding of the causal relationships between website quality constructs and online shopping behavior, with commitment serving as a moderator.
