The relationship between user trust in innovative website design and conversion of consumer response to green product purchase is notably strong (β = 0.203, p-value = 0.014), with user trust accounting for roughly 57.1 % of the variability in consumer conversion ( ). This substantial link suggests that in the broader context, enhancing elements that build trust within a website's design is crucial as it influences over half of the consumer's decision-making process related to green product purchases. Essentially, for industries and markets centered around eco-friendly products, investing in strategies to bolster user trust in their digital platforms could significantly drive consumer response and engagement.
