I want to establish credibility and create trust among my customers to complete their purchase on my ecommerce store. What affects their trust the most? How do I present myself as an authentic seller?
There could be many things affecting your customer's trust in you. You have to research and look at shopping cart abandonment statistics to know what influences their trust the most. For example, research suggests that customers trust an ecommerce website more when they see a PayPal Verified seal. You could add that on your ecommerce website and on your checkout page.
