INTRODUCTION
Thailand is placed ninth with a 10% share of global e-commerce sales in 2021, and 74% of its people between the ages of 16 and 64 have bought something online Boxme Global (2021).The Thai government came up with a two-step plan to grow e-commerce.They think that by 2027, e-commerce sales will bring in 7.1 trillion Baht Arunmas (2022).According to E-Marketer (2017), 188% of Thais use cell

RESEARCH QUESTIONS
These questions align with the study's objectives as following below: 1) What is web design, information quality, security, responsiveness, trust, and customer satisfaction that affect home products through e-Commerce? 2) Have web design, information quality, security, responsiveness, and trust affected customer satisfaction affect home products through e-Commerce?
This study can help home items e-commerce enterprises increase revenue and consumer satisfaction.Businesses can increase sales and profits by determining which aspects of a website's design affect client satisfaction.Improving customer satisfaction can lead to loyal consumers and positive word-of-mouth advertising, which can help e-commerce enterprises even more.Thus, this study improves more than only the user experience.It can also boost Thai home product e-commerce firms.

The study has flaws.First, the study will only examine the Thai home products business; therefore, its findings may not apply to other industries or regions.Second, online poll data may be biased or inaccurate.Third, the cross-sectional study will make linking independent variables to consumer satisfaction more challenging.Fourth, the study will only examine a few website design aspects, which may not cover all e-commerce customer satisfaction factors.The survey will examine consumer satisfaction.Customer loyalty and repeat purchases will not be considered.Despite its flaws, the study will teach us much about e-commerce customer satisfaction, particularly in Thailand's home products market.

LITERATURE REVIEW AND HYPOTHESES DEVELOPMENT 2.1. CUSTOMER SATISFACTION
Customers are happy when their expectations for the buying process and the service they receive after the sale are met, according to Zhang and Nuangjamnong, (2022).Because most things sold through e-Commerce-books, CDs, flowers, electronics, software, etc.-are standardized products, applying this approach to e-Commerce immediately can be challenging.However, with e-Commerce generally, the goods' usefulness and customers' expectations are well matched.According to Satornsantikul and Nuangjamnong (2022), consumers are more likely to be pleased with a product or service if they experience fairness and convenience during the ordering process.Customers are more likely to be dissatisfied with their purchases if they experience unfair treatment or anxiety during the ordering procedure.As a result, a customer's total satisfaction is significantly affected by how they feel about the ordering procedure.Business-to-business trade is something that Mitchev and Nuangjamnong (2021) investigates they claimed to have found a strong link between product satisfaction and customer contentment with the ordering procedure.

WEB DESIGN
One of the theories related to web design is the "Aesthetic-Usability Effect," which suggests that users perceive aesthetically pleasing designs as more usable and effective Tractinsky et al. (2000).Another theory is the "Perceived Credibility Theory," which suggests that website design features such as layout, typography, and color can influence users' perceptions of website credibility Fogg et al. (2001).Previous studies have shown that web design elements such as layout, color scheme, typography, and visual appeal can significantly affect user experience and satisfaction in e-commerce settings Chen and Li (2019), Kim and Moon (2018).These design elements can influence users' perception of website credibility and trustworthiness, which in turn affect their purchase intention and loyalty Hassanein and Head (2007), Kim and Moon (2018).Therefore, the researcher hypothesizes that: Hypothesis 1 (H1): Web design has no a significant positive effect on customer satisfaction in e-commerce settings.

INFORMATION QUALITY
One of the theories related to information quality is the "Expectation-Confirmation Theory," which suggests that users' satisfaction with information quality is influenced by their expectations of the information and their confirmation of those expectations through their experience with the information Bhattacherjee (2001).Information quality refers to the accuracy, completeness, and timeliness of information presented on e-commerce websites Wang and Emurian (2005).Customers rely heavily on product information and reviews when making purchase decisions in online shopping Gao et al. (2014).High-quality product information can reduce uncertainty and perceived risk, increase trust and satisfaction, and ultimately lead to repeat purchase and positive word-of-mouth (WOM) Gefen and Straub (2004), Wang and Emurian (2005).Therefore, the researcher hypothesizes that: Hypothesis 2 (H2): Information quality has no a significant positive effect on customer satisfaction in e-commerce settings.

SECURITY
Security is one of the most important concerns for online customers worldwide.Security credentials provided by an online store, privacy policy, and trust are only some parameters of web shopping security.The more these parameters are developed in a web store, the higher the level of customer satisfaction Corbitt et al. (2003).Most studies about security incorporate this in their research framework and test its influence on satisfaction, and trust Park and Kim (2003).The "Protection Motivation Theory" suggests that users' intention to engage in secure online behavior is influenced by their perceived vulnerability to threats and their perceived effectiveness of security measures Rogers (1975).Based on this, the researcher formed the hypothesis as follows: Hypothesis 3 (H3): Security has no a significant positive effect on customer satisfaction in e-commerce settings.

RESPONSIVENESS
According to the "Technology Acceptance Model," people are more likely to adopt new technologies if they find them useful and straightforward Davis (1989).Customers shopping online may find a responsive website more convenient and user-friendly.According to the "Trust Transfer Model," the credibility of a website is affected by the credibility of the entity with which it is associated, be it a brand or a firm Stewart and Pavlou (2002).The "Social Exchange Theory" is another popular explanation, and it proposes that factors like fairness and reciprocity in interactions shape people's willingness to trust one another Blau (1964).A user's trust in an online store may increase if they believe the site operates fairly and offers mutually beneficial services.Websites are considered more responsive if they provide timely and accurate feedback and support to users Flavián et al. (2006).Customer satisfaction and loyalty can rise or decrease depending on how quickly and effectively their questions and concerns are addressed Chen and Li (2019).Responding promptly to online shoppers' inquiries has increased their satisfaction and loyalty to a brand Flavián et al. (2006), Kim and Moon (2018).This leads the researcher to the following hypotheses: Hypothesis 4 (H4): Responsiveness has no a significant positive effect on customer satisfaction in e-commerce settings.

TRUST
A customer's level of trust in an online merchant indicates their conviction in the latter is dependability, honesty, and ability to deliver on their promises Kumar and Benbasat (2006).Site elements, including aesthetics, content, safety, and responsiveness, all play a role in establishing credibility Gefen (2002), Kim and Moon (2018).Trust has been found to improve e-commerce metrics like consumer satisfaction, loyalty, and conversion Gefen et al. (2003), Kim and Moon (2018).This leads us to the following hypotheses: Hypothesis 5 (H5): Trust has no a significant positive effect on customer satisfaction in e-commerce settings.

CONCEPTUAL FRAMEWORK
As can be seen in Figure 2.3, the conceptual framework has been adopted from the two theoretical frameworks by Lin (2007) framework and Saleem et al. (2022) framework.This study is based on posits that factors such as web design, information quality, security, responsiveness, and trust as independent variables have a substantial effect on customer satisfaction as a dependent variable that is measured through e-Commerce.

SAMPLE
This study used simple random selection to select a sample from a population where every person is equally likely to be determined.This study employed a simple random model to choose survey participants.This survey sampled Bangkok Home Products buyers.The formula for predicting sample size with a confidence level of 95% and a margin of error of 5% yielded 385.
An online questionnaire was used to recruit and target Thai online shoppers; also, this advertisement targets Thai online shoppers from the past year.Age, gender, income, education, employment, and marital status was conducted in the second part of the survey to explain general information about respondents.Because of online shopping has grown among a significant population.This may be owing to extensive internet access.Online consumer databases of popular ecommerce, social networking, and survey platforms can reach this audience.
Thai e-commerce sites.This study samples Thai online buying websites.Online directories, search engines, and other sources will build this list.Thai websites selling home products online are eligible for the sample frame.The list will determine the study's client sample.
• Lazada Thailand -https://www.lazada.co.th/ • Shopee Thailand -https://shopee.co.th/ 1) Obtain a list of online shopping websites in Thailand from a reputable source.2) Assign a unique identification number to each website on the list.3) Contact the selected websites and request permission to conduct the study among their customers.4) Wait for the responses to be returned.5) Use the collected data for analysis.

VALIDITY AND RELIABILITY 3.2.1. CONTENT VALIDITY (IOC)
Overall, the content validity of this study was ensured through a rigorous research design, systematic data collection, and relevant data analysis techniques.All items have greater than 0.5, which IOC weight by three experts shown in Table 1.

RELIABILITY TEST (PILOT TEST)
The reliability of the questionnaire was measured by Cronbach's Alpha coefficient, which indicates the internal consistency of the items.The minimum acceptable value of Cronbach's Alpha is 0.6 Sekaran (1992).Pilot Test -A pilot test will be conducted with a small group of participants before distributing the survey questionnaire to the sample population.The pilot test will help to identify any errors or discrepancies in the questionnaire.In this study, the researcher conducts a small group of 30 respondents for a pilot test, Cronbach's Alpha and internal consistency's rules, refer to Cronbach (1951), the reliability α > 0.9 = Excellent; 0.8 < α < 0.9 = Good; 0.7 < α < 0.8 = Acceptable; 0.6 < α < 0.7 = Questionable; 0.5 < α < 0.6 = Poor; and α < 0.5 Unacceptable.
From Table 2, the research can conclude that Cronbach's alpha of each variable is web design with α = 0.769, information quality with α = 0.775, security with α = 0.806, responsiveness with α = 0.779, trust with α = 0.745, and customer satisfaction with α = 0.748.All factors are above the threshold of 0.6, which means they are reliability.Table 2 presents a reliability test with Cronbach's Alpha results.

RELIABILITY TESTING
To ensure the reliability of the 385 respondents, the researcher conducted a reliability test using Cronbach's Alpha with all respondents.This test aimed to detect any discrepancies or inaccuracies in the items before performing statistical treatment data.
Table 3, the researcher used the statistical program to analyze Cronbach's Alpha to test the reliability of each group of the variables.There are altogether six variables in this study.The factors that affecting of e-Commerce websites on customer satisfaction: a case study of home products users contains six variables, consisting of web design, information quality, security, responsiveness, trust, and customer satisfaction.The results after testing of 385 respondents showed that the items values of each variable are all higher than 0.6, meaning the reliability of six variables are reliable.The variable of web design contains 5 items (α = 0.716), followed by information quality contains 4 items (α = 0.810), security contains 3 items (α = 0.814), responsiveness contains 3 items (α = 0.862), trust contains 3 items (α = 0.829), and customer satisfaction contains 3 items (α = 0.853).

HYPOTHESIS TESTING RESULTS
For this research, it consists of four parts of hypothesis testing which is as follows;

=
The unstandardized beta  = The standardized beta; Beta or β t = The t test statistic Variance Inflation Factor The variance inflation factor (VIF) has been used to determine the amount of multicollinearity in a series of multiple regression.As according to Team (2022), variance inflation factor is a value that reflects the mutual influence of predictors in the linear model.According to Akinwande et al. (2015), the variance inflation factor value would be better to be less than or equal to 5. R-square value uses to measures the performance resulting mathematical model whether it is consistent with the data.
Multiple linear regression was employed in this research framework to estimate the influence of web design, information quality, security, responsiveness, trust, on customer satisfaction regarding to e-Commerce websites of home products users.The information of the results is shown in Table 6.
Table 6 is shown the summary of multiple linear regression which used to analysis affecting of e-Commerce websites on customer satisfaction: a case study of home products users with web design (H 1 ), information quality (H 2 ), security (H 3 ), responsiveness (H 4 ), and trust (H 5 ) on customer satisfaction.R-square was 0.238 or 23.8%.VIFs of H 1 , H 2 , H 3 , H 4 , and H 5 were lower than 5 which means there was no multicollinearity problem.There are significant influence of web design (H 1 , p < 0.000), security (H 3 , p < 0.000), responsiveness (H 4 , p < 0.000), and trust (H 5 , p = 0.025) on customer satisfaction in e-Commerce websites of home products users as all p-value less than 0.05.Meanwhile, information quality (H 2 , p > 0.224) presented non-significant on customer satisfaction in e-Commerce websites of home products users, since p-value greater than 0.05.

DISCUSSIONS AND CONCLUSIONS
The findings of this study indicate that there are four significant factors that affect customer satisfaction, namely web design, security, responsiveneѕѕ, and trust.However, one factor, namely information quality, has been found to insignificantly affected customer satisfaction.Detail will be discussion below.

H1; WEB DESIGN AND CUSTOMER SATISFACTION
There was a significant affecting of web design on customer satisfaction in ecommerce settings as a p-value less than 0.5.This finding aligned with the study by Kidane and Sharma (2016).The e-Commerce website of home product users has a well-organized appearance for their developed home products websites.Also, the e-Commerce website of home product users is reliable for their developed home product websites.To improve web design, it suggests that the e-Commerce website of home product users should improve the visually appealing web design to make customers more interactive appearance.

H3; SECURITY AND CUSTOMER SATISFACTION
This study found a significant effect of security on customer satisfaction in ecommerce settings with a p-value less than 0.5.This finding aligned with the study by Zhang and Nuangjamnong (2022).The e-Commerce website of home product users makes payments for products on their website accurately and quickly.To improve the security of the e-Commerce website of home product users suggests that secure transactions should be the primary concern priority.

H4; RESPONSIVENEЅЅ AND CUSTOMER SATISFACTION
This study found a significant affecting of responsiveness on customer satisfaction in e-commerce settings as a p-value less than 0.5.This finding aligns with previous research by Sigala et al. (2006), in which responsiveneѕѕ positively affects customer satisfaction.The e-Commerce website of home product users gives prompt services and is willing to help customers.To responsiveness of the e-Commerce website of home product users, it is recommended that the customer service content page needs more channels to reach the customer requirement.

H5; TRUST AND CUSTOMER SATISFACTION
This study found a significant affecting of trust on customer satisfaction in ecommerce settings as a p-value less than 0.5.This finding aligns with previous research by Parker and Mathews (2001).Home product users' e-Commerce website builds customer commitment and instills confidence in customers.Meanwhile, to trust the e-Commerce website of home product users, it is recommended that the e-Commerce website needs more effort to develop the contents of home products to be accurate information and trustworthy for their customers.

H2; INFORMATION QUALITY AND CUSTOMER SATISFACTION
This study found an insignificant affecting of information quality on customer satisfaction in e-commerce settings as a p-value greater than 0.5.

CONCLUSION OF FINDING
The findings from the multiple linear regression analysis demonstrate the relative importance of various factors that affect customer satisfaction in Table 7.It is evident that web design, security, responsiveness and trust are the most crucial determinant of customer satisfaction.The ranking of the results from the hypothesis testing is presented in the table 8 below for summary.Table 8 displays the independent variables that affect customer satisfaction, ranked from the most to the least significant influence.The research findings indicate that responsiveness has the most substantial correlation with customer satisfaction, with a coefficient of 0.381.Web design is the second most influential factor, with a coefficient of 0.304, followed by security at 0.186 and trust at 0.175.On the other hand, information quality has no affected on customer satisfaction.

RECOMMENDATIONS
According to the findings of this study, "responsiveness" given at the top rank has a substantial impact on the level of customer satisfaction in e-commerce contexts that involve consumers of home products.When attention was focused on the questionnaire, it was discovered that the item with the lowest mean score was the one that stated, "I believe the online retailer of home product website is never too busy to respond to customer requests."When it comes to response, the consumer needs more attention from the customer care department of the e-commerce website.
According to the results of this research, "web design" comes in at the number two spot.When looking more closely at the questionnaire, it was discovered that the item with the lowest mean score was the one that asked if the online retailer had developed home product websites that were visually appealing.In terms of web design, it is recommended that web developers of e-commerce websites for home products should construct websites that present the product in a more appealing manner.This could include photographs of home items, layouts of contents, detail, price, and so on.
According to the results of this research, "security" comes in third place.When focusing on the questionnaire, it was discovered that the item with the lowest mean score was the one that stated "Generally speaking, making payments on the online retailer of home product website is secure."It was recommended that web developers of e-commerce websites for home products should design the security of ecommerce, cybersecurity, and e-payment transaction in order to instill confidence in customers so that they will shop for home items on e-commerce websites.
Last but not least, "trust" came in at number four on the list of findings from this survey.When we focused on the questionnaire, we discovered that the item "I believe the online retailer of home product website is trustworthy" had the lowest mean score.This was discovered when we focused on the questionnaire.Ecommerce of house products has to establish a website or platform for home products that are more confident and guarantees the quality of service, quality products, and reliable service throughout each stage of the purchasing process, whether it takes place online or offline.This is necessary in order to build trust.

FURTHER STUDIES
Within the context of e-Commerce Websites in Thailand, the current study studied how factors such as website design, information quality, security, timeliness, and trust all play a role in consumer satisfaction and how customer satisfaction influences other factors.In further studies, it may be possible to investigate the impact that the type of device used, such as a mobile phone as opposed to a desktop computer, has on the website design and the level of customer satisfaction.In addition, it would be beneficial to investigate the significance of wellknown online retail platforms in the Thai environment, such as HomePro, IKEA, DoHome, and others like them.In conclusion, the researchers could explore the association between demographic features and consumer satisfaction in various countries.
