Electronic commerce (e-commerce) has been developing to be the new major means of exchange products and services between customers and market. Especially, with the current COVID pandemic, e-commerce has experienced a rapid growth since March (United Nations). Businesses can increase their sales by using e-commerce, especially small businesses. They can advertise their products and services online to the virtual community around the world. E-commerce is simply exchanging goods and services online using the internet between two main parties: Businesses and Consumers. The number of Businesses joining the e-commerce sector has rapidly grown to offer online shopping as a new method of shopping. According to United Nations, the Third-party online marketplaces have increased their sales after joining e-commerce by 35% (United Nation). As the online shopping industry is dominating and keeping up with fashion and brand choice, the number of stores and shopping malls has decreased in the last few years. Customers have more variety from the online shopping malls comparing to the small stores (Akram et al., 2017) .
E-commerce is categorized into four types based on the relationship between the two parties of reciprocity. There are Business to Consumer (B2C), Business to Business (B2B), Consumer to Consumer (C2C) and Consumer to business (C2B) (Nanehkaran, 2013) .
When talking about online shopping, the concept of impulse buying is important to discuss. It refers to any purchases that may be unplanned or sudden as they are usually originated on the spot and are highly correlating with strong willingness and sensations of delight and provocation (Wu, Chen, & Chiu, 2016) . Purchasing products online is more convenient to many customers. Placing orders with one click, getting all the information about the products, having access to all the products, and delivery time are all major factors which lead to buying impulsively online. The vast growth of e-commerce and development of Information Technology helps to make IB prevalent. If online retailers have a better understanding of the factors that encourage online IB, especially in the B2C relationship, there will be a significant increase in the purchases of online industry (Harmancioglu, Finney, & Joseph, 2009) .
According to Rahman, many research papers have proven that there is a high percentage of impulsive buying, which accounts 62% of supermarket sales and 80% of all sales in certain categories of products (Rahman, 2015) . However, Saudi Arabia is still struggling with the growth of e-commerce comparing with its fast economy prosperity (Makki & Chang, 2014) . The limitations of e-commerce lead to lack of knowledge about IB and its advantages of e-commerce.
With regard to IB’s important role in consuming markets and market economy and results, and consuming market evaluation, there is a clear lack of awareness of retailers and sellers about IB, and tools of appropriate use of selling progress are clearly distinguishable by pushing buyers for more consumer market boom as a problem in consuming market especially retailers and sellers. Considering this reality, therefore, that IB is a high percentage of shop purchases, it is necessary to recognize and study effective variable on these purchases until the boom of consumer markets and market economy remains effective. This study will find IB factors for B2C that influence consumers to involve in IB. This study will propose a model, which combines IB factors that influence consumer to buy impulsively, and the result of this study could help marketers in Saudi Arabia to better understand IB factors that influence consumers to buy impulsively to increase their income.
Recent researches are more concentrating on IB in physical stores. While others are focusing on limited factors of IB, there is the need of IB factors in B2C e-commerce in Saudi Arabia. Therefore, this study attempts to propose impulse buying model for B2C e-commerce. The main research question for this study is How to develop an IB model of B2C e-commerce for Saudi Arabia?
Therefore, this research paper addresses the limitations of IB and determines the IB factors that affect customers to purchase impulsively in online shopping in Saudi Arabia. Also, this research paper studies a new model of IB for B2C e-commerce based on the identified IB factors and evaluates the effectiveness of the proposed model in Saudi Arabia.
2. Literature Review
E-commerce has made the reciprocity of goods and services more convenient for the market sector. It is considered important because it is adapting the current IT and communication. These days, e-commerce is dominating over the traditional commerce causing shopping malls and stores to shut down. Customers have the ability to choose and order products on websites wherever they are on virtual networks and get their purchases in front of their houses within a few days.
According to (Britannica, 2020) , the definition of E-commerce, in full electronic commerce, is “maintaining relationships and conducting business transactions that include selling information, services, and goods by means of computer telecommunications networks”. It has four major types: Business-to-Business (B2B), Business to Consumer (B2C), Consumer-to-Consumer (C2C) and Consumer to business (C2B). Business to Business deals between businesses or a transaction that occurs among companies to convey services and goods, such as online wholesaling. Consumer to Business is trading goods or services from individuals to businesses. Consumer-to-Consumer is involving two users or customers conducting transactions between each other. The last one is Business-to-Consumer. Other types of e-commerce include Business-to-Government (B2G), where businesses whose clients are governments or type of public administration, and Consumer-to-Government, where individuals pay taxes to the government or tuitions to colleges (DeMatas, 2019) .
The dominant type of e-commerce is Business-to-Consumer, which refers to transactions, including products and services, occur from the market to consumers. It also refers to online businesses and auctions, such as online stock trading markets, and online auction for different goods. B2C is an online business model where all the transactions happen online via the internet. The main advantage of B2C e-commerce is that it creates a virtual store for customers with minimal capital. Other advantages are providing flexibility, easy communication and fast delivery, and wide variety of items (Mirescu, 2010) . The following Figure 1 shows the relationship between consumers and Businesses in the B2C model (Abumalloh, Ibrahim, & Nilashi, 2020) .
3. Impulse Buying
Foremost, researchers were concerned in comprehending impulse buying. Researchers have put a lot of effort into defining this complex and interesting concept. Many researchers have suggest difference conceptual definitions of impulse buying, unplanned and sudden are the major key words in impulse buying definition (Harmancioglu et al., 2009) . IB is an unplanned buying decision, made unexpectedly before purchasing a product or service. Rook defined impulse buying as a sudden, usually potent and permanent impetus to purchase something instantly (Rook, 1987) . (Karbasivar & Yarahmadi, 2011) based on Rook, (1987) it is concluded that Individual buying impulses are less probably to take through account the consequences or think carefully before purchasing process.
In order to have more profits for businesses, the concept of impulse buying should be taken into consideration. Researchers have been defining that concept as unplanned or sudden purchases by the customers (Harmancioglu et al., 2009) . According to Rook, IB is also defined as “a sudden, usually potent and permanent impetus to purchase something instantly” (Rook, 1987) . This concept depends more on the excitement and emotions of the buyers rather than logic. IB eliminates the idea of thinking carefully before purchasing items and putting in the buyer’s mind that they need the item (Rook, 1987) . There are four different types of IB: Pure Impulse Buying, Reminder Impulse Buying, Suggestion Impulse Buying, and Planned Impulse Buying (Hosseini, Zadeh, Shafiee, & Hajipour, 2020) . The following Figure 2 shows the order of the four types in terms of emotional appeal (Altaf, Shamim, Yousaf, & Ghazali, 2013) .
Figure 1. B2C business model.
Figure 2. IB types from least to most level of emotional appeal.
4. Impulse Buying Classification
By identifying the different types of IB behaviour, the understanding of impulse buying has also been improved. Many factors influenced Impulse buying such as personality traits, website quality and promotion. (Amiri, Jasour, Shirpour, & Alizadeh, 2012) there are four categorizations of impulse buying according to (STERN, 1962) :
1) Pure Impulse Buying. The pure impulse purchase is the most easily eminent form of IB. This is impulsive purchasing, the purchase of novelty or escape that breaks a normal style of buying.
2) Reminder Impulse Buying. Reminder impulse buying happens when buyers see the products and recalls that the inventory is exhaustive at home. The main factor is remembered knowledge of the good that “sparks” the purchase of the impulse.
3) Suggestion Impulse Buying. Suggestion buying happens when customers first see goods and conceives a need for it, although they have no prior knowledge of the products. Item fineness, function, and the like should be evaluated at the moment of buying.
4) Planned Impulse Buying. It may imitate irregular, it is precise. Planned impulse buying happens when the buyers’ login to the web with some buying thoughts, but with the animus to do other buy that rely on offers, low cost and the desire.
All types mentioned previously are from cognitive of consumers about products. While suggestion impulse buying is completely without previous knowledge of the items and without any previous plan to buy, which is the researcher selection as criteria in this study, the planned impulse buying happen with pre plan to buy. Author focuses on the suggestion impulse buying as more type of IB is related to online IB. According to suggestion impulse buying definition, all factors that fall under this type could classify as an IB factors.
According to (Mathur, 2019; Muruganantham & Bhakat, 2013) , Pure impulse buying is escape purchase which a shopper breaks the trend of usual shopping, Reminder impulse buying is when the buyer is reminded of the need of the product during the shopping process, suggestion impulse purchase is the purchase of new products depending on self-suggestion but without any prior intention, and Planned impulse buying is partially planned but specific product or categories are not decided by the shopper (Mathur, 2019; Muruganantham & Bhakat, 2013) .
E-commerce in Saudi Arabia has been growing rapidly over the past few years (Alshehri, 2015) . In 2014, the online sales in the Middle East reached around 7 billion dollars, including $1.5 billion from Saudi Arabia. In 2017, the total e-commerce sales reached $3.076 billion in Saudi Arabia, and it is expected to grow to $9.41 billion by 2021 (Nordea, 2021) . There are several factors for predicting this growth; Saudi Arabia has a strong underlying economic growth, raise the concept of modern retailing, and change some of the cultural concepts like improving the position of women in society. According to (Rahman, 2016) , the Saudi buyers have shown the use of the IB when purchasing. They tend to buy impulsively and go to other products if their preference is not in stock (Rahman, 2015) .
However, the growth expected from researchers is still higher than the current one. According to (Statista, 2021) , the total revenue of e-commerce in Saudi Arabia in 2020 is $6.328 billion, and the expected revenue in 2021 is only $7.051 billion. There was a significant revenue increase from 2019, however it was only due to COVID pandemic (Statistia).
E-commerce in Kingdome of Saudi Arabia is developing and expanding quickly and B2C e-commerce grows rapidly. (Alshehri, 2015) expected that Saudi merchandising revenues will grow from $76.7 billion in 2011 to almost $117 billion in 2015. The main reasons for this predicted growth in Kingdome of Saudi Arabia’s 14 retail sales are: “strong underlying economic growth, rising disposable incomes, increasing acceptance of the concept of modern retailing, a youthful population and an enlarged consumer base created by the improved position of women in society”. The below chart Figure 3 shows the increase in the revenue of e-commerce and the predicted ones for the next 4 years (Statista, 2021) .
Researchers argue that the reason behind this decay is due to several factors that affect the e-commerce IB. There are two kinds of factors: External and Internal. Those factors can affect the people to buy online. For example, the needs for goods is one of the important factors to enhance the online buying. The following Figure 4 shows the relationship between those factors and how they trigger to buy impulsively (Wang, Tauni, Zhang, Ali, & Ali, 2020) .
Many research papers focus on emotions when talking about IB. Emotions have a major impact on the decision that the consumer makes in the shopping process. (Choudhary, 2014) came up with a theory that emotions have a major role in IB. Retailers are aware of that, and they try their best to accommodate the consumer’s feelings (Choudhary, 2014) . Buying helps customers to combat insecurity and give them a sense of completeness. According to (Chang, Eckman, & Yan, 2011) , Customers with more positive emotional reactions were more likely to do IB in the retail environment (Chang et al., 2011) . In addition to that, the mood of the consumer certainly affects their decision while shopping. Excitement and happiness certainly help in encouraging IB, and therefore, increase the revenue of e-commerce.
5. Potential Factors
There are several factors that can affect IB, and therefore, affecting the purchase decision of the consumers. Consumers with a high level of impulsiveness are influenced by the graphics and design of online shopping websites leading them to impulsively buy more items. The following Table 1 shows all the factors from previous studies that influence IB in the Business-to-Consumer type.
6. Extract Factor
According to Table 1, the factors of gender and age were used in 3 different studies, while the income factor was used in 4 studies. The other factors that were used in 4 studies were comments, advertisements, and customer’s impulsiveness. Furthermore, the promotion factor was used in five different studies. Therefore, the selected factors for this study are promotion, impulsiveness, advertisement, income, and comments. The following Table 2 shows in details the factors that affect IB and their definitions.
Table 1. List of IB factor with their definitions.
Table 2. External factors that affect IB.
7. Research Hypothesis
Most of the consumer traits as consumer impulsiveness associate with impulse buying. In both online and offline contexts, a consumer’s impulsiveness as an individual trait has received considerable attention. Past research found that Impulsiveness is greater driver of impulse buying because it is associated with loss of self-control, premeditation and perseverance, all the integral elements of impulse buying behavior (Piyush Sharma et al., 2009) . In an online context, (Wells et al., 2018) , (Chen & Wang, 2016) their research revealed that the individuals with high impulsiveness experience a stronger urge to buy impulsively online compared to individuals with low impulsiveness. Consistent with these findings, a similar relationship should exist between impulsiveness and the Impulse buying in an online context.
H1: Consumers’ impulsiveness has positive impact in impulse buying in e-commerce.
Advertisement plays a crucial role for any business to boost up its performance graph as it is a powerful strategy to attract customers toward particular product. Online and offline research showed the positive impact of advertisement in customers’ buying behaviour. (Malik et al., 2013) found that advertisement has positive impact on consumer buying behaviour and now day’s advertisement a big marketing weapon to attract your customers and to stay in customer’s mind. (Niazi et al, 2012) revealed that the advertisement play a vital role to attract customer’ attention toward the particular product which lead customer to involve in impulse buying. Consumers react to the advertisements are profitable for online shopping. For instance, customers will show more tendency and attention to products through the advertisement. From previous researches, there are good impact of advertisement in buying behaviour whether in offline or online, similar relationship should exist between advertisement and impulse buying in an online.
H2: Advertisement has positive impact in impulse buying in e-commerce.
Sales promotion expenditure is a significant basis of marketing spending that deserves more attention from marketers. The main purpose of sales pro-motion is to have an immediate impact on consumers’ purchase behaviour. The findings of the (Merugu & Vaddadi, 2017) study indicate that there is significantly relation between promotional signage and consumer impulsive buying behaviour. Supported previous findings, researcher (Liao et al., 2009) have found the immediate-reward promotion have strong positive impact on impulse buying. When the consumers face promotion situations, the impulse buying is affected and when online stores provide promotions as cash refund, consumers are affected more easily and it increases their continuous impulse buying (Chen & Wang, 2016) . According to previous findings, exist relationship between promotion and impulse buying online is possible.
H3: promotion has positive impact on impulse buying in e-commerce.
The availability of money is a facilitator in the impulse buying process, since it increases the purchasing power of the individual. The income is one of the factors, which play a vital role in influencing the purchasing behaviour of an individual (Figure 5). Many past researchers found that money availability increases the urge to buy impulsively as well as the likelihood of an individual indulging in impulsive purchase (Jyoti & Verma, 2015) found that money availability have significant positive effect on the construct “urge to buy impulsively” as well as on the construct impulsive buying behaviour. To support that result, (Awan & Abbas, 2015) found as consumers having more monthly income show more impulse buying behaviour and consumers with low income are less impulsive in their purchase decision. Strong impact of income on impulse buying leads to existence relation between income and impulse buying.
Figure 5 Factors that affect IB.
H4: Income of consumers has positive impact on impulse buying in e-commerce.
Online retailers can not only influence consumers by comments, but also can find their shortages and defects in all stages much more easily, and improve their services timely and effectively. Comments and recommendation system has become a part that cannot be missed by any successful online retailer. Some researchers suggest that online consumers can be influenced by comments and recommendation system (Chen, 2012) , (Chen et al., 2014) . By giving some related and fair information, comment and recommendation systems can give the shopper positive shopping experience and increase the level of purchasing satisfaction. This research provides additional evidence that comments and recommender systems do influence online shopping behaviours and can yield positive outcomes for the firms that implement them (Chen & Li, 2009) .
H5: Comment has positive impact on impulse buying in e-commerce.
There are two research approaches that are mostly used in IS research; quantitative and qualitative approaches. A quantitative approach is used to collate numerical data from an experiment or survey to analyses the concept under investigation. A quantitative approach is a suitable choice for deductive methods, when the study is seeking to generalize the results on a large population. This study used a questionnaire-based survey method in order to collect the data. This study used Partial Least Squares, based on structural equation modelling (PLS-SEM) technique to analyse collected data. PLS-SEM is a well-known multivariate analysis method in the IS research field. According to (Urbach & Ahlemann, 2010) there are many reasons to choose Smart PLS v3 such as the phenomenon to be investigated is relatively new and measurement models need to be newly developed, the research model is complex with a large number of factors and indicators and relationships between the indicators and factors. In order to develop the questionnaire, the author follows the next stages in the Table 3.
The targeted respondents for this study are purposive who are familiar with online shopping. Therefore, the respondents should know the meaning of IB and
Table 3. Survey development and validation phase.
if they buy any product in impulse before. According to the scope of research, the target respondents mostly have knowledge and experience in buying items via online shopping.
This study has selected non-probability sampling for following reasons. First, as the targeted respondent to perform this research was customers who have experience in shopping online and knowledge in the meaning of IB, the number of the population is unknown and cannot be individually identified. Second, access to public individually was not handy, since such procedure would be time consuming.
The researcher used G* power software to calculate the minimum sample size required by this study to ensure adequacy of the sample size in the current study. Using the setting proposed by (Dattalo, 2008) which includes ((α = 0.05 and β = 0.80) for error type one and two, effect size = 0.15) and the number of constructs used in the model (6 constructs), the results from G* power software showed that the minimum required number of sample for this study is 98. This means that the sample obtained in this study by the author was 290 exceeds the minimum sample size required. Therefore, the data collected were sufficient for this analysis to evaluate the model. Figure 6 presents the used of G*.
Next Table 4 present the item generation of the questionnaire which used in this study. It presents the construct, construct definition and reference.
Figure 6 G* power software result.
Table 4. Item generation.
9. Results and Discussion
This study will use SmartPLS2 to analyses the data. The demographic information implicates the information about the buyers, such as gender, age, income, if the customers have past experience in shopping online, if they know the meaning of IB and if they have been involved in IB before.
This study finds the demographic information of respondents. Demographic information implicates the information about the buyers, such as gender, age, income, if the customers have past experience in shopping online, if they know the meaning of IB and if they have been involved in IB before. The previous items are adopted from previous studies. The total number of respondents is 290, (81.9%) respondents were female and (18.1%) respondents were male. Next Table 5 describes the demographics of the participations.
The final data analysis consisted of two main steps to come with the results. These two steps are required to test the model and the hypotheses. The first step is measurement model. The second step is structural model (Hair, Sarstedt, Hopkins, & Kuppelwieser, 2014) .
9.1. Assessment of Measurement Model
The determination of how the constructs are evaluated and measured is in the measurement model assessment (Hair, Hult, Ringle, & Sarstedt, 2014) . To assess the measurement model, many tests used to evaluate the internal consistency and evaluate the convergent validity. Also, should see the results of average variance extracted (AVE). Based on the findings of (Hair et al., 2014) . Tables 6-8 will summarize all standards of each test to conduct the assessment of measurement model. Also, Figure 7 shows the results of measurement model.
9.2. Measurement of Structural Model
Assessment of structural model is the next stage after it has been confirmed that all constructs measures are reliable and valid. This study will evaluate the significance and relevance of the structural model. This stage can be done by assessment of the path coefficients (P value) and the calculation of error (T value) and both values can be found by means of bootstrapping. Table 9 present Criteria of Structural Model Assessment.
Figure 7 Measurement model results.
Table 5. Summarize of respondents demographics.
Table 6. Criteria of measurement model assessment.
Table 7. Internal consistency reliability.
Table 8. Convergent validity results based on outer loading and AVE.
Table 9. Criteria of structural model assessment.
9.3. Structural Model Path Assessment
Path assessment follows the collinearity assessment. Path coefficient aims to examine the hypothesized relationships between constructs in the structural model (Hair et al., 2014) . Study found that the standard for path coefficient value is between −1 and +1. If the path coefficient is close to +1, it means there is a strong relation between constructs and that this relation is statistically significant. On the other hand, if the value is close to 0, it means the relationship is very weak and considered not significant statistically. This study used one-tailed test, because all of the hypothesis relationships are directional and all hypotheses expected to be positive. There are critical values for one tailed based on (Hair et al., 2014) which are 1.28 is significant and significant level is 10%, 1.65 is significant relationship and significant level is 5% and 2.33 is significant and significant level is 1%. The T values and P values were obtained by using bootstrapping from Smart PLS. Figure 8 shows the results of path coefficient as presented by using Smart PLS v3.
9.4. Test of Hypotheses
This section will discuss the result of the relationship between the constructs. This study has 5 hypotheses. The results from the bootstrapping test show that 3 out of 5 hypotheses were significant. The results of study hypothesis will show in the next Table 10.
To summarize the hypothesis relationship, the final results showed that consumers’ impulsiveness, advertisement and promotion have a positive effect on Impulse buying in B2C e-commerce for Saudi Arabia. However, the income and comment do not have any effect on impulse buying because the constructs do not achieve the required value. Table 11 presents a summary of hypothesis results.
These results indicate that IB factors have positive effect on impulse buying in B2C e-commerce for Saudi Arabia. Figure 9 shows the final IB model.

Table 11. Evaluation of research hypothesis.
The main aim of this study was to find the IB factors for B2C in Saudi Arabia to increase the shopping online revenue develop the IB for B2C e-commerce model and finally evaluate the proposed model. In the first stage, the author tried to find the most factors influence the IB for B2C from the previous literature. Then, made filtering for factors based on many criteria. Finally, the author developed the model based on selected factors. The study applied a quantitative approach to achieve the proposed research objectives. This study is aimed at finding the IB factors for B2C e-commerce in Saudi Arabia. Consequently, the study did not consider investigating other indicators that influence IB for B2C in Saudi Arabia. The respondents of this study are familiar with online shopping and definition of the IB but most of them have little knowing about the roles of IB in influencing consumers shopping manners, as the result the feedback from the questionnaire may be affected. Besides that, almost more than 80% of the respondents are female which leads to result that are more related to female than male. There are some opportunities for future research in this domain. First, this study uses the IB factors for B2C e-commerce. This can support the B2C e-commerce users to identify more factors that influence online shoppers to buy. This study found the IB factors for B2C e-commerce, future work can be done in B2B or C2B e-commerce.
